Overview
The Allen-Bradley 1746-OW16 is a discrete relay output module engineered for the SLC 500 family of programmable controllers. This digital output module features 16 outputs to facilitate a variety of control applications. This module is a relay output module or sometimes referred as dry contact output module. The modular design with removable terminal blocks enables fast installation and maintenance without full system rewiring.
Key Features
- 16 outputs with each section divided into groups of 8 points for common connections.
- Two input groups with One common terminal per group, allowing one group to operate with a DC voltage while the other group with an AC voltage.
- Removable terminal block which is color-coded for easy identification, eliminating the concern of having to disconnect wiring to replace a module.
- 120VAC break rating of 15 A, 240VAC make rating of 7.5 A, and continuous AC current of 2.5 A.
- Normally Open relay contacts for general-purpose industrial switching

- Backplane Current Consumption: 0.17A backplane current consumption at 5V DC and 0.18A at 24V DC
- Common Configuration: Two input groups with One common terminal per group
Typical Applications
Designed for SLC 500 series systems, it offers both Normally Open operation and flexibility with multiple common points for a broad range of automation tasks. SLC 500 programmable controllers provide excellent value with extensive capabilities to address a broad range of applications including material handling, HVAC control, high speed assembly operations, small process control, simple motion control, and SCADA.
The dual-voltage configuration makes this module ideal for systems requiring both AC and DC relay switching without interposing relays or external circuits.
