Allen-Bradley 1746-OA16 SLC 500 AC Output Module 16-Point
The Allen-Bradley 1746-OA16 is a robust digital AC output module for the SLC 500 controller family. This module provides sixteen discrete outputs for switching AC loads. It delivers a nominal output voltage of 120/240 VAC. The operating voltage range spans from 85 to 265 VAC. This flexibility makes it suitable for global applications. Engineers use this module to control motors, valves, and lights. It integrates seamlessly as a local or remote I/O module. The unit works with SLC 500, CompactLogix, and ControlLogix processors. This ensures broad compatibility across your automation architecture.
Technical Specifications for the 1746-OA16
The 1746-OA16 module offers sixteen outputs in two isolated groups. Each group contains eight channels for organized wiring. Each output delivers 0.50 A at 30 °C. At 60 °C, the current derates to 0.25 A per point. The maximum continuous current per module is 8.0 A at 30 °C. This value drops to 4.0 A at the higher temperature limit. The module draws only 370 milliamps from the 5.1V backplane. This low power consumption eases system power supply planning. The ON signal delay measures a fast 1.0 millisecond. The OFF signal delay is longer at 11.0 milliseconds. The OFF-state leakage current is a minimal 2 mA. This prevents unwanted load activation during the off state.

Expert Installation & User Guide for the 1746-OA16
Installing the 1746-OA16 module is a straightforward process. First, ensure the SLC 500 chassis power is off. Then, slide the module into a single slot. Secure it firmly using the top and bottom locking tabs. The module uses a 16-bit I/O memory space. You can access output values easily using Ladder Logic. The removable terminal blocks simplify wiring and future replacements. You do not need to disconnect wires when swapping modules. This design saves significant maintenance time. The module includes filter circuitry and optical coupling. These features reduce electrical signal noise effectively. The LED indicators on the front panel show each output status. This makes troubleshooting quick and intuitive. Always verify the load current does not exceed 10 mA minimum. The module operates reliably in temperatures from 0 to 60 °C. It also tolerates 5 to 95% noncondensing relative humidity. This environmental range covers most industrial floor conditions.
