ATP168 - Analog to Potentiometer

Product Diagram

The ANALOG TO POTENTIOMETER isolating signal converter ATP168 can convert most process signals into a potentiometer output. The potentiometer consists of a series of true resistors that can be switched with 1 in 255 (8 bit) resolution.

Typical applications:

  • Replace mechanical pot used for control of existing machinery;
  • Automatic control of gain or offset in instrumentation;
  • Provide programmable adjustment for Delays, Filters or Time Constants.

The ATP168 provides true 3-way galvanic isolation up to 2000V r.m.s. between various input signal types to potentiometer output to power supply. Connection can be made as a 3-wire pot or 2-wire variable resistor.

The output signal level is indicated by a green L.E.D. on the front of the module, giving a clear indication of module function, signal presence and loop condition for current outputs. Various power supply choices are available ranging from 240Vac down to 8dc. All provide power isolation and surge protection.
