GE IC660BBS101 Isolated I/O Block

This isolated I/O block provides high-density discrete control for Genius I/O networks. The GE IC660BBS101 combines input and output channels in a rugged field-mounted enclosure. Sixteen isolated channels serve as either inputs or outputs based on configuration. Consequently, automation engineers can adapt this block for mixed signal requirements without extra hardware.

Technical Specifications of the Isolated I/O Block

The GE IC660BBS101 measures 203 mm in height and 178 mm in width. Its depth reaches 89 mm for standard panel or DIN rail mounting. The block weighs approximately 1.8 kg including all terminal and isolation components. A single front panel LED array shows network status and per-channel fault conditions. The bottom side features two sealed conduit entries for field wiring. This design stores minimal energy in small filtering capacitors only. Therefore, the block contains no batteries or large energy storage elements.

Functional Features and Configuration Flexibility

The GE IC660BBS101 allows you to configure each channel independently from the bus controller. You can set any channel as an input or output without changing jumpers. The block automatically reports fault status for short circuits and overload conditions. Each channel includes built-in surge suppression for inductive load protection. Consequently, this isolated I/O block suits harsh industrial environments near motors and drives.

Installation and Network Integration

You must mount this I/O block on standard DIN rail or a flat panel. The GE IC660BBS101 requires a shielded twisted-pair cable for Genius bus connection. A single 24V DC power supply feeds both logic and field circuits. The block automatically assigns network addresses through rotary dials on the front panel. Always verify channel configurations before connecting field devices to the system.

Maintenance and Environmental Benefits

Because the GE IC660BBS101 stores no battery-backed data, it needs no periodic battery changes. Technicians can replace the block without losing any configuration settings. The sealed NEMA 4X enclosure resists water, dust, and corrosive atmospheres. Consequently, this I/O block provides reliable service in outdoor and washdown applications.
