Description

COMECO’s signal isolator TRIL is a compact 2-wire current-to-current transmitter providing optical isolation of 3750 VAC between the input and output current loops. It is designed for mounting on a 35 mm DIN rail according to EN 50022, and is available in 2 variants:

passive: an entirely passive device, which does not generate any supply voltages and does not need any additional supply to operate; the input part is powered by the input current loop (4…20 mA), and the output part is powered by the output current loop;
active: uses the energy of the output loop power supply (3-wire connection) to generate an isolated supply voltage for the input loop; provides an increased input over-voltage and over-current protection.
