Galvanic isolation barriers separate low-voltage Flexbus microprocessing logic from high-voltage field contact circuits, preventing electrical transients and voltage inductive spikes from corrupting internal bus registers. High-speed packet synchronization maintains deterministic communication latency across active network drops, ensuring predictable relay response times during sequential control execution.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 1793-OW4S require an external power source in addition to Flexbus backplane power?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module draws 5 VDC @ 70 mA from the internal Flexbus for logic processing and requires an external 24 VDC @ 125 mA field power supply to energize the internal relay coils.\u003c\/p\u003e\n\u003cp\u003eQ: What are the maximum continuous switching ratings for each relay output channel?\u003c\/p\u003e\n\u003cp\u003eA: Each relay contact is rated for a maximum continuous switching current of 2 A across operating voltages up to 125-240 VAC or 30 VDC.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eSnap the module firmly onto its compatible terminal base or mounting rail until the retention lock engages. Connect the external 24 VDC coil power supply terminals using properly sized conductors. Maintain a minimum physical separation of 100 mm between low-voltage Flexbus signal lines and high-voltage AC load wiring routed through panel wireways. Ensure inductive field loads (such as solenoid valves and motor starters) are equipped with external surge suppression devices across their coil terminals to prevent inductive arcing and extend contact life.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52783468806424,"sku":"1793-OW4S","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1793-OW4S_83553084-2e4e-4272-8e5f-4956be1afadd.png?v=1790584064","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1793-ow4s-flex-compact-digital-output-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
