Important note:

• Product information:
• The non-adjustable DC isolating amplifier ACT20M-CI-CO-S isolates analogue standard current signals.
• An analogue input current signal is linearly converted to an analogue output current signal and is galvanically isolated.
• 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 non-adjustable DC isolation amplifier ACT20M CI-2CO-S offers the same functionality but has 2 galvanically isolated outputs (4-way isolation).
