ACT20M-CI-CO-OLP-S Details

The ACT20M-CI-CO-OLP, WAS/WAZ5 OLP signal isolator/splitter (2-wire system) is supplied via the output current loop and has an analogue DC current input. The 1- and 2-channel signal isolators are supplied from the current loop. They are available in the 6.1 mm (ACT20M series) or 17.5 mm (WAVESERIES) housings.

The input and output circuits are electrically isolated from each other. 

The power is supplied via the 4–20 mA current loop on the output side.

The devices come optionally in a splitter version with two loop-fed outputs.

The devices can be mounted on a DIN rail and consume minimal power. 

International approvals (such as ATEX Zone 2, UL C1D2 and FM Div2) permit use in explosion-risk zones. 

Signal converters with output-loop power supplies are used in a variety of application processes as signal isolators and signal multipliers (splitters) and signal amplifiers. They can be used to eliminate measurement errors caused by differences in earth potentials.
