Allen-Bradley 1734-IR2 – POINT I/O isolated relay module

The Allen-Bradley 1734-IR2 is a POINT I/O isolated relay module featuring two isolated form-A (SPST) relay outputs driven by a 24 V DC coil. It is intended for distributed I/O architectures where electrical isolation between control logic and field outputs is required. The module provides switching interfaces for discrete loads, allowing control of devices such as signal lamps, solenoid valves and low-power actuators through relay contacts.

Each relay output has an isolated contact set, providing electrical separation that protects the control system from load-side transients and noise. The 1734-IR2 mounts via the POINT I/O terminal base on a DIN rail mounting system and supports organized field wiring and module serviceability.
