Important note
Product information The configurable DC isolating amplifier ACT20M-AI-AO-S isolates and converts analogue standard signals. An
analogue input signal is linearly converted into an analogue output signal and galvanically isolated. The input
can also be operated as an active current loop (the loop current is supplied by the device). The power supply is
galvanically isolated from the input and output (3-way isolation) by means of direct wiring or the Weidmüller rail
bus.
The configurable DC isolation amplifier ACT20M-AI-2AO-S offers the same functionality, but has 2 galvanically
isolated outputs (4-way isolation).
