How to Split and Rescale Signals


Split one signal into two signals?...and rescale it too? One interface does it all.

You can do it with the ARM2.

Input a signal to ARM2 and output 2 current signals!

 

Use it to:

  1. Shrink or expand a signal range.
  2. Convert a resistance signal into two current signals.
  3. Convert a voltage signal into two current signals.
  4. Reverse the action of a signal

ARM2 offers convenient features like:

  1. Top adjust pots for gain and offset
  2. Jumper selectable input ranges to make setup easy

ARM2 can also be ordered calibrated to your specifications for a modest charge.

Signal Current Booster

Here's the answer to a signal power problem - a current booster.
The AS A outputs 2.05 amps (up to 30 watts). You can use the ASA's"beefy" current output to control M/MR series of MaxitrolTM modulating gas valves (yes they are usually operating in cold temperatures)...ASA is now operable to minus 40 OF or 40 OC.
AS A can be used for control of dimming ballasts.
The AS A will also re-scale a voltage or current signal, or convert a resistance signal to a voltage output.
AS A offers convenient features like:
  1. Top adjust pots for gain and offset
  2. Jumper selectable input signal ranges
  3. Jumper selectable zero, positive or negative offset
  4. A replaceable fuse
This is a real problem solver if you need flexibility and power in making your signal transition.

Introducing the new TEC3000 COLOR Thermostat

The TEC3000 Color Series Thermostat Controllers are wireless, stand-alone, and field-selectable BACnet® MS/TP or N2 networked devices that provide on/off, floating, and proportional control of the following:

  • Local hydronic reheat valves
  • Pressure-dependent VAV equipment with or without local reheat
  • Two- or four-pipe fan coils
  • Cabinet unit heaters
  • Other zoning equipment using an on/off, floating, or 0 to 10 VDC proportional control input
  • Single- or two-stage control of unitary rooftop units (RTUs)
  • Single- or two-stage control of RTUs with economizers
  • Single- or two-stage control of heat pumps
  • Single- or two-stage control of heat pumps with economizers

With the upcoming release of the color TEC3000 models, the monochrome TEC3000 models will be discontinued. All monochrome TEC3000 models have an equivalent color TEC3000 replacement model. The attached cross reference sheet lists the discontinued monochrome TEC3000 product numbers and their replacement products.

The final date to accept monochrome TEC3000 orders is July 31, 2019, unless stock runs out earlier. The Buy America models are set to discontinue whenever stock runs out.

What’s new:

  • JCI Global Product Design Language Standards provide modern design, impactful use of color, and enclosures in black and white design themes.
  • Bright, high-definition capacitive touchscreen display provides responsive feedback and improved readability of text and icons.
  • Improved temperature compensation and protections against installation variability.
  • Auto/Heat/Cool Override Available from Home Screens.
  • All models include integrated humidity sensor.
  • TEC3x10, TEC3x11, TEC3x20, and TEC3x21 monochrome models will no longer be available. Reference models with humidity sensor instead.
  • Dehumidification control is currently not available with the RTU/Heat Pump models, but will be made available very soon.
  • Configurable Hi/Low incremental actuator capability added to the TEC3x1x models.

What stays the same:

  • All applications, communication options, and features will carry-over from the current TEC3000 models.
  • Identical footprint and mounting to monochrome TEC3000
  • Menu navigation and settings are consistent with current models.
  • Default firmware language – English, French, Spanish
