GE IC660EBA100 Genius I/O Module | 16 Inputs 12 Outputs

The IC660EBA100 functions as a Genius I/O module for GE distributed control systems. This unit provides discrete input and output capabilities on a single device. It communicates directly with a Genius bus controller over twisted-pair cable. Therefore, this module eliminates the need for a separate PLC rack at remote locations.

Input Characteristics and Processing

The IC660EBA100 provides sixteen discrete inputs for field device connections. These inputs accept both sink and source wiring configurations automatically. Each input includes optical isolation from the internal logic circuits. Consequently, electrical noise on field wiring does not affect module operation.

Output Design and Load Handling

This Genius I/O module features twelve sourcing DC outputs for actuator control. Each output uses MOSFET technology for fast, wear-free switching. Individual outputs handle up to 0.5 amperes at 24V DC continuously. The module provides flyback diode suppression for inductive loads internally.

Genius Bus Communication

The IC660EBA100 connects to the Genius LAN through two independent ports. Port A and Port B support daisy-chain or redundant cable configurations. The module transmits input data to the bus controller every bus scan. It simultaneously receives output data from the controller for its twelve points.

Diagnostic Capabilities

This I/O module includes eight LED indicators for comprehensive status reporting. A green Power LED confirms the presence of 24V DC supply. The Bus OK LED lights when communication with the controller works properly. I/O LEDs show the real-time status of each input and output point. Therefore, maintenance personnel can diagnose faults without any test equipment.

Energy Storage and Power Interruption

The IC660EBA100 contains internal capacitors for brief power ride-through. These capacitors maintain operation for up to 20 milliseconds during voltage dips. The module does not include any battery for data retention. All output states return to a user-configured safe state upon power loss.

Installation and Bus Wiring

Mount the IC660EBA100 onto a standard DIN rail using the integral clips. Connect 24V DC power to the dedicated input terminals on the module. Wire the Genius bus cable to Port A and Port B terminals as needed. Terminate both ends of the bus segment with 100-ohm resistors. Set the bus address using the rotary switches before applying power. Always verify the address matches your controller’s configuration.
