Description
The Allen Bradley 1771-OA is an AC Output Module. This module contains the circuitry needed to control the on/off status of eight user devices. The device can be a motor starter, indicator, and solenoid motor; its output can drive the Allen-Bradley Size 4 starter motor, providing that the supply voltage does not drop below 92 Volts of AC power. The maximum load current that this unit can provide is 1.5 A per channel, not more than 6 A total per module. A power supply connected to the I/O backplane chassis is required to power the unit; it requires a maximum current of 210 mA at 5 Volts of DC power. The total requirements of this module are currently with other modules in the I/O chassis to avoid oversupply or rear axis I/O chassis.
