Allen Bradley 1746-OB16 SLC 500 Output Module

The 1746-OB16 is a 16-channel digital output module belonging to Allen-Bradley’s SLC™ system (compatible with SLC50X series controllers), designed for mid-range industrial control scenarios. It adopts a transistor output type and DC voltage drive, specializing in switching control of external DC-powered devices such as solenoids, relays, and small motors.

With a wide input voltage range (10–50V DC), the module offers flexibility for different industrial power supply configurations. Each digital output channel can provide a maximum current of 0.5A, while the overall module supports a total output current of 8A, meeting the drive requirements of multiple low-to-medium power devices simultaneously.

The module features a compact structural design that fits the SLC system’s standard single-slot installation, with dimensions optimized for chassis space utilization. It is not suitable for safety-related functions and is intended for general industrial control applications. The module operates stably in harsh industrial environments, with strong adaptability to temperature and humidity variations, ensuring reliable output signal transmission in typical factory settings.
