General
Acrel BM800-RPSI/I-11 is a 6.2 mm thick signal isolator mountable on DIN 35 mm rails. It adopts a 1-in-1-out channel configuration with galvanic isolation among the input, output and power supply terminals. It isolates and transmits 0–20 mA or 4–20 mA current signals from the input to the output. The input side is compatible with 2-wire, 3-wire and 4-wire transmitters, and the device operates on a 24 V DC power supply.
