GE Fanuc IC660BBA024 Current Source I/O Block

Description

The IC660BBA024 is a versatile current source I/O block from the GE Fanuc Genius I/O Series, designed for industrial automation. This module connects seamlessly with devices that generate 4-20 mA analog signals. It features 4 independent inputs and 2 outputs, both of which are factory-calibrated for precision. To enhance performance, the module includes linear scaling capabilities, which simplify the conversion of analog signals into engineering units.

Each input channel provides a 24 V current loop power supply, while the outputs handle 4-20 mA current loops efficiently. For reliable performance, all input and output circuits include diagnostic features such as underrange and overrange alarms. Additionally, the module’s robust design incorporates isolated channels, ensuring safety and durability in demanding environments.

To facilitate analog-to-digital conversion, the IC660BBA024 uses a voltage-to-frequency converter. Unlike many other modules, it powers directly through a 24-48 VDC supply, which connects to its DC terminals. Moreover, users can connect a compatible Bus Switching Module (BSM) for extended functionality.
