Overview
The Allen-Bradley 1746-OW16 Series C is a digital output module featuring 16 outputs designed for SLC 500 series systems. This module is a relay output module, sometimes referred to as a dry contact output module, making it ideal for controlling AC and DC loads in industrial automation applications.
Key Features
- 16 relay outputs with each section divided into groups of 8 points for common connections
- Operating voltages of 5–125V DC and 5–265V AC
- Operates under Normally Open conditions for versatile circuit configurations
- 10 ms signal delay in both ON and OFF states at maximum resistive load
- Removable color-coded terminal block that eliminates the need to disconnect wiring during replacement, with wiring barriers and self-lifting pressure plates for secure connections
- Ideal for mixed voltage applications where one group operates with DC voltage while the other operates with AC voltage
Technical Specifications
At 120VAC, the break rating is 15 A and make rating is 1.5 A; at 240VAC, the make rating is 7.5 A and break rating is 0.75 A, with continuous current for AC operation at 2.5 A.
