MasTec Power Relays

 

 OEM only > Low Cost DIN Rail
Smart Power Control Modules

Three Model Types

230 VAC 10 Amp Relays or PNP or NPN Power Transistors

 

 Do you need to control AC or DC Power from your controller - Micro, Computer, PLC, PAC or ??

These No Progamming DIN Rail Smart Relays - AC or DC Power Switches, can control up to 50 outputs > Relays 10A 230VA or 80VDC 2A PNP or NPN power transistors.

Your Control voltages can be 3.3, 5, 12, 24 or you decide in the field the DC level.

There are several models and levels of this product.

First decision in purchase is what type of power do you want to run them on > AC (90-260VAC) or DC (12-24VDC).

This table has the various models with switching and control levels, plus adjustabliity.

From the table you can see there are four basic model types available >

Simple AC Control with 0 volts or less than 50%- Off and greater than 50% is on

Simple DC Control with 0 volts or less than 50% - Off and greater than 50% is on

Factory Preset DC Control with 0 volts or less than 1 volts - Off and Preset threshold for On level between 1 - 30VDC is On

Field Adjust DC Control with 0 volts or less than 1 volts - Off and FIled threshold for On level between 1 - 30VDC is On

With these base four models and variations on output types, there are 80+ different models to choose from.

Plus deciding on AC or DC power and output and input count.

You will not find a product as versatile as this with a lower price and more flexibility and options.

This technology can be applied in many situations > Building, Automation Control, Field Sites with linkage to PLCs, PACs, Embedded Computers and Micro Processor systems

Controlling almost anything such as motors, lamps, fans, pumps, irrigation valves, lights etc

 A more full discussion on MasTec Range

What makes them Smart ?

The AC controlled modules have

  • An invert logic input
  • A master input which releases all outputs

The DC controlled modules have

  • An invert logic input
  • A master input which releases all outputs
  • Digital input control
  • Additionally there are various models with Analog inputs that have adjustable On levels and Off levels

There are three categories of inputs in these DC products.

Each has a different levels for Input thresholds for deciding when to turn On and when to turn Off.

  • Simple Threshold set at the factory
  • Preset Threshold set and Flashed by MasTec at your ordering time
  • Adjustable Threshold set by you in the field or on the bench

Some examples of the models available :-

Simple model - Input threshold levels set at factory manufacture time

Typical cases:-

1/ You need to control power relays or power transistors with AC Input levels 0-110VAC or 0-240VAC.

Purchase a Simple AC Smart Power Controllers > control logic levels automatically adjusted correctly with hystersis for 90 to 250VAC, with no adjustments.

2/ You need to control power relays or power transistors with DC Input levels of 12 or 24 VDC?

Purchase a Simple DC Smart Power Controllers > control logic levels automatically adjusted correctly with hystersis for 12 to 24VDC,

 

Preset model -- we flash the input thresholds at your ordering time

You need to control power relays or transistors with non standard PLC, PAC, Computer Output Logic Levels

Typical Cases are

1/ You need to control power relays or power transistors use using any of these logic types - PC digital I/O system (TTL - 5VDC), a Micro (3.3 VDC), a Controller ( 9 VDC) or a PLC ( 12 VDC )?

Purchase a Preset DC Smart Power Controllers > We program the input thresholds you desire > Just connect and it will run correctly

 

Adjustable model -- adjustable by you in the field or on the bench

You need to control power relays or power transistors with DC Input levels in a range 0 -10 VDC, either using a logic control signal or a varying analog input like temperature or pressure.

Typical Cases are

1/ You need to control power relays or power transistors with a varying DC signal from a field gauge like a temperature transmitter, pressure gauge or flow meter etc

Purchase an Adjustable Smart Power Controller > just connect a varying 0-10 VDC input and adjust the Hi and Lo analog threshold levels inputs at setup time in the field and you can control power at the level you choose and have a hystersis level to get stable operation.

Additional Control Inputs:

  • Input line to "Invert Data", to allow correct control for inverted logic
  • Input line that does a "Master Release" on all outputs
  • Input line to "Invert the logic of the Master Release" line to allow correct control for inverted logic
  • Special models have > An Input line for "One Shot Timers Master Release"
  • Special models have > An Input line for "Latching Outputs Master Release"

Special models have > Additional Features and Models

  • One Shot Timer Models
  • LCD Display for I/O levels Models
  • Latching output Models

 The Extend Details for the MasTec Range

Spec -- MasTec has 80 +Power Controller models :-

  • On all models there is an "Invert input line" allow reversing the input data logic - allows either sinking or sourcing data inputs etc .
  • On all models there is a "Master Output release - input line" that allows the controller to release all outputs to open.
  • On all models there is an "Invert Master Output release - input line" that allows either a sinking or sourcing control line to release all the outputs. A sinking system can go Hi rather than Lo and release the outputs.
  • LCD Display option to show input and output states
  • One shot option Preset with a timer that makes the output go to ON for x Seconds/minutes/hours when a threshold is crossed and then off again. "Early reset OS input line".

 Technical Notes:-

Set Models - Factory Set Input thresholds Off/Open <=5VDC and On/Closed => 10VDC (none adjustable in the field)

Preset Models - At Buy Time the Preset Input levels are specified and flashed Off/Open 0-10VDC and On/Closed 0- 10VDC, You choose the level, Off must be less than On level -- of course. (none adjustable in the field)

Field Adjustable Models - Both On and Off Input levels are set in the field by connecting the required threshold voltage levels to specific threshold adjustable inputs using potentiometers or voltage dividers. Off/Open 0-10VDC and On/Closed 0- 10VDC, You choose the level in the field or on the bench, Off must be less than On level -- of course. (adjustable in the field)

Field Adjustable & Preset Models - The On Input levels is set in the field by connecting the required threshold voltage levels to specific threshold adjustable input using potentiometers or voltage dividers. (adjustable in the field)
Off/Open 0-10VDC. (none adjustable in the field)You choose the off level and tell us. Off must be less than On level -- of course.

Threshold and Hystersis Note:

The field adjustable thresholds allows the user to tune the relay or transistors power controller module in the field to give custom levels of hystersis for stable operation wiout chatter or over sensitivity to input changes.

It can also be used to allow analog levels, not necessarily logic level systems, to control the relays/transistors. This means controlling on a hi and lo level, temperature, pressure, humidity, level etc--- almost any analog industrial system 0-10VDC, even 4-20mA systems using shunt resistors.

For Logic Level systems, having adjustable input threshold levels, makes it possible to connect these relays /transistors power control modules to almost any digital logic level - 3.3 or 5 VDC for PC or micro outputs or any non standard systems

Some of the models available- there are 2 AC models and 21 DC models - add options - OS or Display or Latching = 80+ models

Options:-

Add -lcd --- for the LCD display function and module - LCD Displays Display of the input and output states.

Add -os --- for the One Shot function - this makes the output turn on for a Preset time using a timer in the power controller. At purchase time you will need to advise the OS time so it can be programmed in. An additional Set input allows all the OS timer to be reset.

Add -latch --- for the Latch Output function - this makes the output turn on when the input cross the on threshold and makes the output turn off again when the same input level goes below the off threshold level and back up to the on threshold level. In other words there has to be two cycles of the input from off to on to ff to on to turn the output on and off. An additional Set input allows all the Latching Outputs to be reset.
