The Allen-Bradley 1771-OA PLC-5 AC Discrete Output Module is a modular component of the 1771 I/O system, requiring a properly installed system chassis. The maximum adjacent slot power dissipation should be limited to 15W maximum. Connections to the module are made via the 1771-WA field wiring arm shipped with the module. The arm pivots on the chassis to connect with the 8 terminals on the front of the module. The wiring arm allows the module to be removed from the chassis without disconnecting wiring.
The 1771-OA contains the circuitry necessary to control the on/off status of eight user devices. The devices can be:
- AC motor starters
- Indicators
- Solenoids
An output can drive an Allen-Bradley Size 4 motor starter, provided its supply voltage does not drop below 92VAC. The maximum load current the module can deliver is 1.5A per channel, not to exceed 6A total per module.
