Detailed Feature Overview

GE IC660BBS102 provides 8 isolated inputs and 8 isolated outputs in one block. This design handles both AC and DC voltages without configuration changes. The unit accepts 115 V AC or 125 V DC on any channel. Consequently, you can mix AC sensors and DC actuators on the same block.

Each channel features 1500 V RMS optical isolation for safety. This isolation protects the Genius network from field wiring surges. The outputs handle 1.0 A continuously for small motors or valves. A 1000 µF capacitor stores energy for brief power interruptions. It holds output states steady for 15 milliseconds during dips.

Genius Network Integration

This block includes a built-in bus interface for direct Genius LAN connection. It communicates with the PLC without any separate adapter module. The unit transmits input status updates every 8 milliseconds. It receives output commands from the processor within 4 milliseconds. Dual bus ports support redundant cable connections for fault tolerance.

Installation and Wiring Guidelines

Mount the block on standard 35 mm DIN rail or use four M4 screws. The unit weighs 0.82 kg for secure mounting. Two removable terminal blocks simplify wiring replacements. Use 14–18 AWG stranded copper wire for all field connections. Strip wires to 8 mm before inserting into terminals. Operating temperature ranges from 0°C to 60°C reliably. Keep humidity below 95% without condensation for long life.
