GE IC660BBD110 I/O Module

Input Architecture and Field Device Compatibility

The GE IC660BBD110 functions as a Genius I/O block with 16 input circuits for field device connectivity. It accepts 115 VAC signals from both 2-wire and 3-wire switch inputs. This module provides reliable interface between field sensors and the Genius bus system. It supports applications requiring high-density AC input monitoring in industrial environments.

Each input circuit features optical isolation to protect the Genius bus from field-side electrical noise. The module automatically detects the presence of 2-wire or 3-wire devices without configuration changes. Consequently, engineers can deploy this block in mixed input scenarios with minimal setup effort.

Physical Specifications and Environmental Ratings

The IC660BBD110 measures 18.0 cm in height, 11.5 cm in width, and 5.2 cm in depth. It weighs approximately 0.85 kg, providing robust construction for harsh industrial settings. This module features a sealed housing that protects internal components from dust and moisture. It carries a NEMA Type 4X rating for indoor and outdoor applications requiring washdown capability.

A removable terminal strip accommodates field wiring for all 16 input connections. This terminal strip accepts wire sizes ranging from 0.2 to 2.5 mm² (24 to 14 AWG). The module includes integral mounting feet for panel or DIN rail installation without additional hardware.

Power Requirements and Energy Storage

This Genius block draws 25 VA from the 115 VAC input power source for internal operation. It incorporates energy storage capacitors that maintain input status during brief power interruptions. These capacitors provide approximately 20 milliseconds of hold-up time to prevent nuisance fault reporting. The module also features transient protection circuits that suppress voltage spikes from inductive field devices.

Technical Specifications

System Integration and Genius Network Communication

The IC660BBD110 connects directly to the Genius bus for seamless integration with GE PLC systems. It communicates with Series 90-30, Series 90-70, and other Genius-compatible controllers. Users can configure the module using hand-held monitors or programming software for address assignment and diagnostic monitoring. This block supports hot insertion for maintenance without disrupting network communication.
