Description
Allen-Bradley 1734-OW4 POINT I/O Relay Output Module
The Allen-Bradley 1734-OW4 serves as the primary 1734-OW4 Relay Output Module utilized to execute electromechanical relay switching of field loads across POINT I/O distributed I/O platforms. The module provides four normally-open isolated relay outputs, communicates through the POINT I/O backplane, and supports control of AC or DC field circuits through dry-contact relay interfaces.
Suffix Breakdown & Model Matrix
The supplied documentation identifies a single catalog number, 1734-OW4. No official suffix variants or ordering matrix information are provided in the source material.

Backplane Communication and I/O Density Scaling
The 1734-OW4 exchanges control data through the POINT I/O backplane and occupies a compact distributed I/O footprint. Within POINT I/O architectures, relay output modules can be combined with digital, analog, and specialty modules on the same backplane segment, allowing I/O density expansion without altering controller logic structure. Backplane communication manages output state transfer while field-side relay contacts provide galvanic separation between the control system and connected loads.
Frequently Asked Questions
Q: Does the 1734-OW4 use solid-state outputs or mechanical relay contacts?
A: The module uses four normally-open isolated electromechanical relay outputs rather than transistor-based outputs.
Q: Can the module switch outputs at high frequency?
A: No. The specified maximum switching frequency is one operation every 3 seconds at rated load, reflecting the characteristics of mechanical relay contacts.
Q: What backplane load does the module place on the POINT I/O system?
A: The module draws 90 mA from the 5 VDC POINT I/O backplane supply.
Field Installation Guidelines
-
Install the module inside a protective industrial enclosure because the unit is specified as an open-style device.
-
Verify that terminal conductors and connected loads remain within the relay contact ratings specified by the system documentation.
-
Route relay output wiring separately from low-level analog signal wiring to reduce electromagnetic interference.
-
Ensure adequate cabinet ventilation when multiple relay modules are installed in adjacent slots.
-
Follow POINT I/O keying and terminal-base installation procedures before energizing field circuits.
-
Inspect relay-controlled inductive loads and apply appropriate suppression devices where required by the load manufacturer.
