Internal solid-state driver circuits update all 32 transistor sourcing outputs in real time while maintaining deterministic EtherNet\/IP communications with CompactLogix and MicroLogix 1500 controllers. High I\/O density scaling allows total module output loads up to 16 A continuous across expansion banks, remaining within specified power supply distance limits of 8 modules without compromising firmware flash compatibility or backplane bus communication velocity.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the integrated electronic protection manage overcurrent faults on individual channels?\u003c\/p\u003e\n\u003cp\u003eA: The onboard electronic short-circuit protection detects excessive current conditions across the transistor output drivers and trips the faulted channel, automatically resetting once the fault clears and junction temperatures normalize.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum allowable distance between this 32-point output module and the system power supply?\u003c\/p\u003e\n\u003cp\u003eA: The 1769-OB32T features a power supply distance rating of 8, requiring installation within 8 module slots of a 1769 expansion power supply to guarantee valid backplane voltage levels.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eIsolate system backplane power and field-side VDC voltage sources before installing or servicing the module assembly. Latch the housing onto a standard 35 mm DIN rail or panel backplate, verifying that the backplane interconnect slides securely into the adjacent module connector. Terminate field output wiring to the 1769-RTBN18 removable terminal block using 22 to 16 AWG stranded copper wire rated for 90 deg C. Route DC signal conductors separately from high-voltage AC lines and drive cables to prevent inductive noise pickup and preserve channel switching isolation.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52902661751096,"sku":"1769-OB32T","price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/284.1.jpg?v=1788427364","url":"https:\/\/www.automodulexpert.com\/products\/allen-bradley-1769-ob32t-compactlogix-dc-output-module","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
