MeloAuto-Trusted PLC & DCS Parts Supplier
The GE IC660BBR101 provides isolated relay outputs for Genius distributed I/O networks. You can mount this block on a DIN rail or panel in remote locations. It switches AC or DC loads directly from PLC control signals. This block suits motor starters, solenoid valves, and heating elements.
Technical Specifications and Hardware Layout
This relay output block measures 210 mm in height. Its width reaches 160 mm, and the depth equals 55 mm. The GE IC660BBR101 weighs approximately 1.1 kilograms. A single internal PCB holds all relay driving and isolation circuits. The block contains no energy storage capacitors or batteries. One 20-pin removable terminal block handles all field wiring connections. Two 9-pin D-sub connectors provide the redundant Genius bus interface. Eight red LEDs display the output status for each channel.

Output Specifications and Electrical Ratings
The GE IC660BBR101 features eight form C relay output channels. Each relay switches 3 A at 250 V AC or 30 V DC maximum. The total output current per block reaches 10 A. Each channel provides both normally open and normally closed contacts. Consequently, this flexibility suits both energize-to-run and energize-to-stop applications. The block requires an external 24 V DC power supply for operation. Genius bus communication uses a redundant configuration for high reliability. Relay contacts include silver-cadmium oxide material for extended service life.
Installation and Communication Guidelines
You must mount this block on a DIN rail using the integral clips. Transitioning to wiring, use 0.5 mm² to 2.5 mm² stranded copper wire. Two rotary switches set the block address from 0 to 31 easily. The block supports Genius bus baud rates of 153.6 kbit/s. Eight front LEDs show output status and bus activity. The operating temperature range spans from -20°C to +70°C reliably.
