Allen-Bradley |1771-OW16| Electromechanical Relay Contact Output Module
Description
The 1771-OW16 Series B is a modular component of the 1771 I/O system, designed for use with a properly installed system chassis. It features 16 electromechanical relay contact outputs that can drive inputs of 1771-ac/dc input modules to indicate statuses such as motor starter activation. The module includes status indicators for each output, showing when the corresponding relay is energized.
Features
- 16 output relays with status indicators.
- Supports ac/dc (240V ac/150V dc) input modules.
- Provides channel-to-channel isolation for operating voltages over 125V.
- Includes a field wiring arm for easy installation and removal without disconnecting wiring.
