Product Description

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. 1746-OB16 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), 1746-OB16 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.

1746-OB16 features a compact structural design that fits the SLC system’s standard single-slot installation, with dimensions optimized for chassis space utilization. 1746-OB16 is not suitable for safety-related functions and is intended for general industrial control applications. 1746-OB16 operates stably in harsh industrial environments, with strong adaptability to temperature and humidity variations, ensuring reliable output signal transmission in typical factory settings.
