The 2080-LC50-48QWB is a Micro 850 logic controller manufactured by Allen Bradley. The unit has 28 24-volt DC or AC inputs, as well as 20 output relays for a total of 48 I/ OS, plus 6 HSC supports. It consumes about 33 watts of power and should provide a power supply between approximately 20.4 and 26.4 volts of direct current (Class 2). The input channel of the controller operates in the 110 V AC voltage category with a maximum of 132 V AC (60 Hz). Its off state voltage is up to 20 volts AC. At 132 volts AC, it has a maximum off current of 1.5 mA and a maximum on current of 16 mA. For signal wiring, the controller wire size is required to be 0.2 to 2.5 square millimeters (or 24 to 12 AWG), using solid or stranded copper wire. Its signal, power, and communication ports do not exceed two (2) wires per port and must be strictly limited to copper wires. Its insulation is stripped up to 7 mm (or 0.28 in).
