1 Module accepts four digital input signals and provides four digital outputs. It connects to a local bus that is interfaced to a Profibus-DP / PROFINET network by a Profibus Interface Unit (IC677PBI001) / PROFINET Interface Unit (IC677PNS001).

Connect FE using a mounting screw, or on a non-conductive surface using a cable connection to the FE connection point. Ensure IP67 Protection. Cover the unused sockets with protective caps (IC676ACC002 and ACC003). Avoid Damage to the Electronics. Supply the sensors with the appropriate voltage U S at the connection points. In general, the maximum current load of 4A per contact must not be exceeded. Avoid Polarity Reversal of supply voltages U L, U A and U S. Connect sensors to correct points (shown on next page).
