The 6ES7131-6FD01-0BB1: This module mounts on a BU type B1 BaseUnit, which handles the wiring interface for 1-wire, 2-wire, 3-wire, and 4-wire sensors. For 4-wire connections, you also need a potential distributor module. The module is 20 mm wide and 73 mm tall, fitting standard ET 200SP rail layouts. Shielded cable runs up to 1000 m; unshielded up to 600 m.
It requires a BU type B1 BaseUnit for 1-wire, 2-wire, and 3-wire connections. For 4-wire sensors, add a potential distributor module.
Signal "0" is 0 V AC to 40 V AC; signal "1" is 74 V AC to 264 V AC. Rated voltage is 230 V AC.
Minimum 1.5 ms, maximum 4 ms for 0-to-1 transition; 10 ms for 1-to-0 transition.
