Universal standard signal isolating amplifier
1-channel signal isolating amplifier in 6.1 mm width with external power supply,
for transmitting and isolating analogue DC current signals 0/4...20 mA and voltage signals
0/2...10V // 0/1...5 V. I/O signals are configured with DIP switches.
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).
