Deterministic network performance is sustained by processing 4 discrete AC channels with high scanning throughput while drawing only 75 mA from the internal POINTBus. Firmware flash compatibility enables consistent I\/O synchronization across Point I\/O mounting assemblies, supporting scalable channel density while maintaining strict AC switching profiles.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the backplane current draw of the 1734-OA4 module?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 75 mA at 5 VDC directly from the POINTBus logic backplane.\u003c\/p\u003e\n\u003cp\u003eQ: How does ambient temperature affect the output current capacity of the 1734-OA4?\u003c\/p\u003e\n\u003cp\u003eA: The module delivers a full 2 A total rating up to 113 deg F (45 deg C), after which it derates uniformly down to 1.4 A at temperatures above 131 deg F (55 deg C).\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAlign the 1734-OA4 module over the mounting base assembly and push firmly into the slot until the lock mechanism latches onto the DIN rail.\u003c\/li\u003e\n\u003cli\u003eWire field AC loads to the terminal block, verifying output current does not exceed 0.75 A per channel and total module current stays within thermal derating limits.\u003c\/li\u003e\n\u003cli\u003eEnsure power distribution wiring matches the specified 120 to 240 VAC operational limits (264 VAC maximum) to prevent component overvoltage stress.\u003c\/li\u003e\n\u003cli\u003eMaintain separation between high-voltage AC load lines and low-voltage network bus connections to prevent electro-magnetic interference on the POINTBus communication backplane.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48793751519422,"sku":"1734-OA4","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1734-OB8E_1200x1200_3132ca44-5d93-4511-b7f0-3cbccd33bee9.jpg?v=1787881173","url":"https:\/\/www.autooiltech.com\/ar\/products\/allen-bradley-1734-oa4-point-i-o-digital-ac-output-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
