The IC660BBS102 is a versatile Isolated I/O Block designed for industrial automation applications by GE Fanuc, operating within a voltage range of 115 VAC and 125 VDC. This unit features eight output circuits organized into four groups of two, each capable of handling a load current of 2.0 Amps. Built with robust diagnostics capabilities, the IC660BBS102 continuously withstands voltage levels of up to 250 VAC/VDC between any group or ground, and offers a transient rating of 2000V peak for 10 seconds. Key features include configurable AC/DC circuit voltage settings, selectable input filter types ranging from 10ms to 100ms, and output pulse testing capabilities. The block is equipped with diagnostics for overload detection, power loss, over-temperature protection, and open wire detection on tristate inputs. An OVERTEMPERATURE message is triggered when operating temperatures exceed 100°C, automatically shutting off the circuit to protect internal electronics. It supports easy field wiring, accommodating one AWG #12 or two AWG #14 wires per terminal, with terminals labeled 1 to 4 suitable for ring terminals up to 0.27 inches in size. The recommended torque for all terminal connections is 6 inches/lb. The IC660BBS102 is fully compatible with the GE Fanuc handheld monitor IC660HHM501 and other GE Fanuc bus controllers, while offering backward compatibility with earlier versions of Genius I/O blocks. It must be installed in a protective enclosure to avoid airborne contaminants and ensure proper cooling. Mounting options include both right side up and upside down installations, with a minimum spacing of 2 inches between blocks. Technical specifications include an operating temperature range of 32 to 140 degrees Fahrenheit, a storage temperature range of -40 to 212 degrees Fahrenheit, and a weight of 4 pounds. The dimensions of this output block are 8.8 x 3.3 x 3.9 inches.
