Ensure backplane current draw is within chassis capacity. Use signal wires no larger than 2 mm² (14 AWG) to maintain proper terminal connection. No additional mounting hardware is required.\u003c\/p\u003e\u003cp\u003eAfter insertion, connect the DC power supply (20.4–26.4 VDC) to the module’s output terminals. The module automatically resets after a fault once power is cycled and the error source is corrected.\u003c\/p\u003e\u003ch2\u003eTroubleshooting \u0026amp; Common Issues\u003c\/h2\u003e\u003cp\u003eThe front panel \u003cstrong\u003eE-FEUSE\u003c\/strong\u003e LED illuminates when a channel experiences a short circuit or overload. If lit, remove system power, correct the fault, and reapply power. The module will automatically recover and resume normal output.\u003c\/p\u003e\u003cp\u003eFor fuse replacement, use Littelfuse #322010 or #332010 (10A). The \u003cstrong\u003e1746-F8\u003c\/strong\u003e kit from Allen-Bradley contains five spare fuses. Always replace the fuse with the module powered off and removed from the chassis.\u003c\/p\u003e\u003cp\u003eIf multiple channels trigger the E-FEUSE simultaneously, verify the external load and wiring. The module’s individual channel protection ensures other outputs remain operational during a single-channel fault.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing, confirm the \u003cstrong\u003e1746-OBP16\u003c\/strong\u003e matches your SLC 500 system’s backplane current requirements (250 mA at 5V). Verify the output voltage range matches your load specifications. For high-current applications, this module supports up to 1.5 A per output (derated to 1 A under certain conditions).\u003c\/p\u003e\u003cp\u003eUBEST Automation (ubest101) stocks genuine \u003cstrong\u003eAllen-Bradley 1746-OBP16\u003c\/strong\u003e modules with fast worldwide shipping.
