GE Fanuc IC660EBA020 Genius I/O Analog Block Electronics Assembly

The GE Fanuc IC660EBA020 is an electronics assembly designed for the GE Genius I/O IC660BBA020 / IC66BBA020 voltage/current analog block. Positioned as the processing unit of the modular block assembly, the IC660EBA020 plugs into a compatible terminal assembly (such as the IC660TSA020) to handle signal conversion, processing, local data storage, and serial communication across the Genius I/O network.

Analog Signal Processing and I/O Capabilities

The unit contains four 12-bit analog input channels and two 12-bit analog output channels. It supports selectable signal ranges including 0–10 VDC, ±10 VDC, ±5 VDC, 0–5 VDC, 0–20 mA, and 4–20 mA (or 1–5 VDC). Analog inputs deliver an update time of 4 milliseconds with selectable software filtering up to 1024 milliseconds. The module maintains a maximum accuracy of ±0.5% full scale with a thermal drift rating of 40 ppm/deg C.

Power Requirements and Fault Management

Operating across an 18 to 56 VDC supply range with an 8.0-watt maximum power rating, the assembly provides high reliability under industrial operating conditions. Outputs can be configured to hold their last state or drop to zero upon loss of CPU communication. Two front-panel LEDs provide diagnostic feedback on module state and bus communications.

Frequently Asked Questions

Q: Which terminal base is required to mount the IC660EBA020 electronics assembly? A: The IC660EBA020 requires a compatible Genius I/O terminal assembly, such as the IC660TSA020, which provides physical field wiring terminals, serial bus taps, and mounting support.

Q: How do the analog outputs behave if communication with the host CPU fails? A: The two 12-bit analog outputs can be pre-configured during setup to hold their last valid state or default to zero in the event of a CPU communication loss.
