1771-OAD
IN STOCK NEW SEALED
1771-OAD Allen-Bradley PLC-5 Digital Output Module, (16) 120V AC Digital Outputs, 2A/each, Fused, Operating Voltage: 10-138V AC; Wiring Arm: 1771-WH.
1771-OAD Pre-installation Considerations.
The module is compatible with all chassis except 1771-A1, 1771-A2 and 1771-A4 chassis. Any discrete input module may be used within the same module group.
1771-OAD Power Requirements.
Your module receives its power through the 1771 I/O chassis backplane from the chassis power supply. The module requires 295mA from the output of this supply. Add this to the requirements of all other modules in the I/O chassis to prevent overloading the chassis backplane and/or chassis power supply.
