Detailed Feature Overview

GE IC660TBD024 combines 12 DC inputs and 12 DC outputs in one block. This design saves space compared to separate terminal blocks. All inputs and outputs use sink-type wiring configuration. The common terminal connects to the positive supply voltage. Consequently, field devices switch the negative side to ground.

Each output handles 0.5 A continuously for small actuators. The total current per common group cannot exceed 4 A. A 470 µF capacitor stores enough energy for brief power interruptions. It holds output states for 10 milliseconds during dips. Therefore, the block prevents nuisance tripping of critical outputs.

Genius Network Communication

This terminal block communicates via the Genius LAN protocol. It requires a separate bus interface module for network connection. The block receives output commands from the PLC processor. It sends input status updates every 10 milliseconds. Four diagnostic LEDs show network health and block status clearly.

Installation and Wiring Guidelines

Mount the block on standard 35 mm DIN rail or use four M4 screws. The unit weighs only 0.54 kg for easy handling. Two removable terminal blocks simplify wiring replacements without rewiring. Use 16–22 AWG stranded copper wire for all field connections. Strip wires to 7 mm before inserting into terminals. Operating temperature ranges from 0°C to 60°C reliably. Keep humidity below 95% without condensation for long life.
