1. Product Overview
IC660TBA026 is the wiring terminal base assembly for GE Genius 6-channel current analog input module IC660EBA026; the complete assembled unit model is IC660BBA026. It is a modular distributed I/O base under the GE Fanuc Genius fieldbus system, installed on standard DIN rail, acting as the physical wiring bridge between field 4~20mA pressure/temperature/flow transmitters and the internal analog sampling electronic core IC660EBA026.
Equipped with 24 compression screw terminals, it provides dedicated wiring points for 6 groups of 4–20mA two-wire transmitters, distributes 24/48VDC field sensor power, and integrates Genius bus communication wiring terminals for data interaction with the main PLC via Genius serial bus. A dedicated HHM handheld monitor port is reserved on the front panel for on-site module parameter configuration, signal calibration and fault diagnosis without upper computer software.
Built-in multi-stage RC filter and surge absorption circuits suppress industrial electromagnetic interference; each analog channel supports open-circuit wire break detection, over-range / under-range signal alarm, and uploads fault codes to the PLC control system. Onboard EEPROM solidifies channel scaling, fault reporting enable/disable and redundant CPU configuration parameters, supporting output last-value hold function during communication failure.
Adopts explosion-proof Class1 Div2 hazardous area certification, full industrial anti-corrosion plastic shell, suitable for long-term stable operation in high-dust, high-EMI power plant, petrochemical and oil & gas automation cabinet environments. It cannot operate independently and must be paired with IC660EBA026 analog electronic core to form a complete 6-channel analog input Genius I/O station.
This model is classic legacy spare hardware for GE Genius distributed control systems, widely used for DCS cabinet transformation, transmitter signal channel maintenance and fault replacement.
