Description

The General Electric IC660BBS102 is an 8-circuit isolated input/output block designed for operation within Genius I/O distributed control architectures. Operating at a nominal 115 VAC or 125 VDC, this robust hardware module features four isolated groups of two I/O circuits each. It includes integrated diagnostic capabilities such as a Failed Switch feature that reports discrepancies between commanded output states and internal switch feedback.

Engineered for reliable industrial performance, the unit supports flexible configuration options including AC or DC circuit voltages, output pulse testing, selectable input filter times, and output power-up defaults. Its modular architecture consists of a terminal assembly and electronics assembly, enabling straightforward replacement and maintenance without disrupting existing field wiring.

Features

Supports AC or DC circuit voltage configurations (93-132VAC / 105-132VDC) Isolated I/O block featuring four groups of two circuits each with 1500V block-to-block isolation Failed Switch diagnostic monitoring for IC66*BBS102 variant Selectable input filter times ranging from 10ms to 10ms increments up to 100ms Output pulse test capability and configurable output hold last state or default options Built-in electronic fusing with automatic short-circuit shutdown and recovery Advanced diagnostic reporting for open wire, overtemperature, overload, no-load, and loss of I/O power

Applications

Distributed industrial automation and process control systems Discrete manufacturing lines requiring isolated AC or DC signal monitoring High-reliability PLC architectures utilizing Genius communications bus Harsh industrial environments requiring robust surge and transient protection

Technical Specifications

Connections / Interfaces

The module connects to the Genius serial bus via terminals 1 through 4 using recommended twinaxial cable types. Power connections support up to five separate power sources across the terminal assembly, allowing circuit power and block power to be configured independently as AC or DC. Field devices wire directly to terminal pairs (8, 9, 12, 13, 16, 17, 20, 21), accepting AWG #12 solid wire or dual AWG #14 wires.

Installation Guidelines

Mount the unit within a clean, protective enclosure ensuring at least 2 inches of clearance above and below for cooling airflow. Secure the block using 8-32 mounting hardware with star washers to guarantee structural and ground integrity. Connect the dedicated green ground screw to a reliable earth ground system using a minimum AWG #12 wire lead. Configuration is performed via a compatible Hand-held Monitor (such as IC66*HHM501) connected to the serial bus.
