This module provides sixteen (16) sinking DC outputs, allowing the PLC to control 24V DC to 48V DC loads. As a sinking module, it functions by completing the ground (negative) side of the circuit, providing a reliable path to the common return for connected field devices.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSixteen (16) independent sinking output channels.\u003c\/li\u003e\n\u003cli\u003eFast switching performance with a 0.1 ms ON-signal delay.\u003c\/li\u003e\n\u003cli\u003eTransistor-based output design for high-cycle, long-life operation.\u003c\/li\u003e\n\u003cli\u003eIntegrated surge current protection capable of handling 3.0 Amps for 10 ms per point.\u003c\/li\u003e\n\u003cli\u003eDesigned for seamless integration into the SLC 500 chassis backplane.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe 1746-OV16 is widely used in industrial automation environments for controlling DC-operated actuators, relays, solenoid valves, and indicator lamps.
