Integration

Mounts on a BU type U0 base unit, supporting 2-, 3-, and 4-wire sensors. For 3- or 4-wire sensors, a potential distributor module is required. 1- and 2-wire connections work directly through the base unit. Unshielded cable runs up to 600 m; shielded up to 1 000 m. Response time from '0' to '1' is 15 ms max, and 20 ms max from '1' to '0'. Rated voltage is 48 V AC (also 24/48 V AC at 50/60 Hz) or 48 V DC. Isolation tested at 1 200 V DC between supply and backplane. Typical power loss is 1.5 W.
