Product information
Product information The software configurable Universal Transmitter ACT20M-UI-AO-S separates and converts standard analogue
signals. An analogue input signal (voltage, current, resistance, potentiometer, RTD, TC) is converted linear and
galvanic isolated into an analogue output signal. The input may also operate as an active current loop (the loop
current provided by the device). The power supply is galvanically isolated from input and output and happens
via a direct wiring or the Weidmüller DIN Rail Bus (3-way isolation).
