Key features of the 1734-OB2 module include:

Two output channels: The module supports two digital output channels, each capable of providing a discrete signal to a connected device.

Isolation: The module offers channel-to-channel and channel-to-bus isolation, helping to protect the system from noise and interference.

High-current output: Each output channel is capable of sinking or sourcing up to 2.0 amps of current.

Configurability: The module can be configured using the programming software associated with the system it is connected to.

Diagnostic LEDs: The module includes diagnostic LEDs that provide status information about the module and its channels.

The 1734-OB2 module is commonly used in industrial automation applications, where it can be connected to a Programmable Logic Controller (PLC) or other types of control systems. It allows the control system to switch digital signals to various devices, such as solenoids, motors, valves, or indicator lights.
