Product Summary
The Allen-Bradley 1746-OV8 delivers eight robust sinking output channels for your SLC 500 system. This module controls high-current DC loads with a wide 10-50VDC operating range. Its single-slot design installs directly into any SLC 500 chassis. Engineers trust it for reliable discrete control in demanding industrial environments.
Expert Technical Evaluation & Performance Review
Output Power and Current Handling
The 1746-OV8 provides a continuous output current of 1.0 A per point at 30 °C. This rating drops to 0.50 A at 60 °C. The module delivers a total of 8.0 A at 30 °C. It handles 4.0 A at the maximum operating temperature. Each channel withstands a surge current of 3.0 A for 10 milliseconds. This capability supports high inrush loads like solenoids and contactors.
Signal Response and Switching Dynamics
This module achieves an Off-to-On signal delay of just 0.1 milliseconds. The On-to-Off delay measures 1.0 millisecond with a resistive load. These fast transitions enable precise timing in your control sequence. The maximum Off-state leakage current stays at 1 mA. The minimum load current requirement is also 1 mA. This ensures clean switching without false triggering.
Environmental and Regulatory Compliance
The unit operates reliably in temperatures from 0 to 60 °C. It survives storage conditions from -40 to 85 °C. The module handles 5 to 95% relative humidity without condensation. It carries UL and C-UL listings for Class I, Division 2 areas. The CE and C-Tick marks confirm compliance with international standards. It withstands a 30g operating shock for rugged industrial use.
Installation and Wiring Features
The module occupies a single slot in any SLC 500 chassis. Its backplane draws only 135 mA at 5 Volts DC. Self-lifting pressure plates accept up to two 14 AWG wires each. Color-coded removable terminal blocks simplify wiring and troubleshooting. Front panel LEDs display the real-time status of each I/O point. You can use pre-wired cables or a 1492 interface module for connections.
