Terminal Assembly | GE Fanuc IC660TBA023 Genius I-O

The GE Fanuc IC660TBA023 is a modular plug-in terminal base assembly designed for the Genius I-O distributed automation system. It serves as the physical interface for field wiring, providing secure signal routing and isolation within 24 VDC or 48 VDC control loops. Featuring an operating voltage window of 18 VDC to 56 VDC, this terminal assembly allows for efficient field device connection and simplified module replacement.

Electrical Characteristics and Signal Handling

The IC660TBA023 features a 1500 V RMS isolation rating between control circuits and field signals, preventing high-voltage transients from affecting system backplanes. It maintains continuous operation through brief line disturbances, tolerating power dropouts up to 10 ms. The terminal base includes open-wire detection logic with a 5-second response time for timely diagnostic alerting, along with a 400 ms gate time frequency for signal sampling.

Environmental and Mounting Design

Designed for modular panel mounting, the assembly withstands industrial environments with up to 1 g vibration resistance and operational altitudes up to 2000 m. Heat dissipation is specified at 9 W. The unit operates reliably within a temperature range of 0°C to 60°C and copes with non-condensing relative humidity up to 95%.
