The GE Fanuc VersaMax Micro PLC Expansion Unit, part number IC200UEX009, offers a robust solution for expanding control capabilities in automation systems. This unit supports eight AC inputs and provides six relay outputs, including two outputs rated at 10 Amps and four outputs rated at 2 Amps, requiring a nominal input power of 100VAC to 240VAC. The AC input circuits are designed for reactive (resistor/capacitor) loads, necessitating an AC power source for operation, as they are incompatible with DC power supplies. The input circuits are versatile and can interface with a variety of devices, including pushbuttons, limit switches, and electronic proximity switches, with the caveat that external power is required to operate these field devices. Additionally, the six normally-open relay outputs can actuate an array of devices, such as motor starters, solenoids, and indicators. The two 10 Amp relay outputs are provided individually, while the four 2 Amp relay outputs are grouped together. Power for the internal relay coils is sourced from the unit itself, but separate external AC or DC power must be supplied to energize the field output devices.
