Overview
Output Configuration and Operation
The 1769-OW8 provides eight normally open relay output channels. Each channel uses a relay contact to switch an external load rather than generating an electronic output voltage directly. Therefore, the connected field circuit must have an appropriate external power supply.
The module supports AC and DC switching within its specified operating voltage ranges. Meanwhile, its 10 ms ON signal delay is an important consideration when evaluating output response requirements.
Wiring and Installation
The module features a replaceable terminal block, which provides access to field wiring connections. Its removable door label also allows technicians to record module specifications and terminal assignments for maintenance reference.
In addition, the 1769-OW8 supports DIN rail and panel mounting. It occupies one slot in the Compact I/O configuration and draws power from the system backplane.
