Analog 2-wire Transmitter for Potentiometer Input

DB537 is designed for input signal from potentiometers and has an adjustable measuring range from 100 Ω up to 100 kΩ. The unit has a very short response time, which makes it ideal for valve and actuator feed-back.

DB537 provides an output signal, 4-20 mA, that is easily matched to the end positions of a valve or an actuator.

  • Potentiometer input in 3-wire connection
  • Adjustable for measuring ranges from 100 Ω to 100 kΩ
  • 4-20 mA output
  • Ideal for valve and actuator feed-back due to short response time (~100 ms)
  • Front potentiometers for matching the output signal to the working range of the valve or actuator
  • Test output connection without breaking the loop
  • Plug-in terminals simplifies connection and disconnection
  • DIN-rail mounting
