The IC660BBA100 is a high-performance analog I/O block from the GE Genius series, designed for robust industrial automation applications. This module operates at a rated voltage of 115 VAC and features four independent input circuits alongside two independent output circuits, accommodating a broad spectrum of analog I/O devices. Each input circuit is capable of handling a range of signals, including -5 volts DC to +5 volts DC, -10 volts DC to +10 volts DC, 0-5 volts DC, and 4-20 mA/1-5 volts DC, as well as 0-10 volts DC. The four input circuits share a single 12-bit analog-to-digital (A/D) converter, converting incoming analog signals into digital count values that are subsequently expressed in engineering units. The two output circuits employ a 12-bit digital-to-analog (D/A) converter to transform the processor's output signal back into an analog format.

Accuracy specifications indicate a tolerance of 50 mV on the 10V range, 5 mV on the 5V range, and 100 µA on the 4-20 mA range. An internal power supply supports current-mode output for loads up to 300 ohms, while external power supplies of 24 VDC or 48 VDC are required for higher loads up to 2,000 ohms. The IC660BBA100 includes several advanced features such as independent scaling for each input and output, programmable fault reporting capabilities, and alarm detection with configurable low and high limits. Additionally, outputs can be set to maintain their last state or revert to default conditions if communication with the processor is interrupted. This versatile block is compatible with any handheld monitor, though special configuration is required when interfacing with the IC66HHM501 model.

Technical specifications include a weight of 4 pounds, heat dissipation of 6 watts, and strong isolation of up to 1500 volts between blocks, making the IC660BBA100 a reliable choice for various industrial applications.
