Product Description P/N: 1734-OW4
Description
The Allen-Bradley 1734-OW4 is a POINT I/O relay output module with four normally open (SPST) contacts. It provides discrete output switching for both AC and DC loads, supporting voltages of 5–30 VDC, 120 VAC, and 250 VAC. Designed for distributed I/O architectures, the module mounts on a DIN rail and connects through compatible POINT I/O terminal bases. It is widely used in industrial automation systems requiring compact, reliable, and flexible relay outputs.

Information About 1734-OW4
The 1734-OW4 is part of the Allen-Bradley POINT I/O family, developed to deliver modular and space-saving I/O expansion. This relay output module offers four isolated Form A contacts with ratings up to 240 VAC/2A or 30 VDC/2A. It has a POINTBus current draw of 80–90 mA at 5 VDC and dissipates 0.5 W of power. The module achieves isolation up to 250 V, tested at 2550 VDC for 60 seconds between field and system. Designed for use with terminal bases such as 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS, it enables flexible wiring and installation. Compatible with POINT I/O communication adapters, including EtherNet/IP, ControlNet, and Profibus, the 1734-OW4 integrates seamlessly with Allen-Bradley controllers such as CompactLogix and ControlLogix. With a rugged open-style enclosure and T4/T4A temperature rating, it ensures reliable performance in demanding industrial environments.
Key Features:
- Design: Compact POINT I/O relay output module for distributed control.
- Outputs: Four SPST normally open relay contacts.
- Voltage Range: Supports 5–30 VDC, 120 VAC, and 250 VAC loads.
- Current Rating: 2 A per contact (load dependent).
- Isolation: 250 V tested at 2550 VDC for 60 s between field and system.
- Performance: ON/OFF transition delay approx. 20–26 ms.
- Power Consumption: POINTBus current draw of 80–90 mA @ 5 VDC, 0.5 W dissipation.
- Durability: Contact life expectancy up to 100,000 operations (load dependent).
- Mounting: DIN rail installation with compatible terminal bases (1734-TB, TBS, TOP, TOPS).
- Environmental Ratings: Operating temperature –20…55 °C, shock 30G, vibration 5G, IP20 open-style enclosure.
The 1734-OW4 delivers the reliability and flexibility required for distributed automation and discrete control in industrial environments.
