Acrel BM800-TC/VI-11 Signal Isolator
Acrel BM800-TC/VI-11 Signal Isolator
General
Acrel BM800-TC/VI-11 is a 6.2 mm thick signal isolator for DIN 35 mm rail mounting. It features 1-channel input and 1-channel output with galvanic isolation between the input, output and power supply circuits. This device converts thermocouple signals at the input side into isolated DC signals including 0/4-20 mA, 0/1-5 V and 0/2-10 V at the output. The measuring range and output signal type can be configured via DIP switches. It supports Type K and Type J thermocouple inputs, and the rated supply voltage is 24 V DC.
