APCS RT124 Resistance Transmitter

The APCS RT124 Resistance Transmitter converts resistance to a DC signal with a slidewire or potentiometer input up to 10k ohms. It features 2000Vrms isolation, link-selectable output ranges, and front span/zero adjustments. Suitable for actuator feedback, process signal adjustment, and system checks.

The APCS RT124 is a DIN-rail signal conditioning transmitter that converts a resistance input into a DC signal. It accepts a 3-wire slidewire or potentiometer up to 10 kohm and produces an output up to 18 V DC or 50 mA DC, with 2000 Vrms isolation between input, output and supply.

Output ranges are link-selectable, zero and span are adjusted from the front, and it runs from all common AC or DC supplies. It is typically used to send valve or damper actuator position feedback to a PLC, re-transmit position for remote indication, or modernise older slidewire instruments. See the RT124 datasheet.

Applications

The APCS RT124 Resistance Transmitter is suitable for actuator feedback, process signal adjustment, and system checks:

  • Converting valve/damper actuator position feedback (slidewire) to a DC signal
  • Interfacing potentiometer-based position sensors with PLC analogue inputs
  • Process signal scaling and adjustment between field devices and control systems
  • System commissioning checks and loop verification
  • Retransmitting actuator position for remote indication
  • Isolating resistance-based feedback signals from control system earths
  • Converting legacy slidewire transmitters for modern 4-20mA style systems
  • Providing calibrated span/zero adjustment for actuator feedback loops
