The 1734-OW4 module provides four digital output channels. Each channel can be used to control an external device or actuator by switching the voltage applied to it. The module supports sourcing output type, meaning it can provide power to the external devices.

The 1734-OW4 module communicates with the PLC (Programmable Logic Controller) or other devices over the backplane of the POINT I/O system. It uses a digital communication protocol, typically EtherNet/IP or ControlNet, to exchange data and receive control signals.

The module is designed to offer flexibility and easy configuration through its removable terminal blocks, which simplify the wiring process. It also supports hot-swapping, allowing modules to be added or replaced without interrupting the operation of the system.
