Power logic components draw 165 mA directly from the 5 VDC chassis backplane supply. Integrated surge capability allows outputs to handle inrush currents up to 4.0 A for 1 millisecond intervals.\u003c\/p\u003e\n\u003ch3\u003eInterfacing and Installation Requirements\u003c\/h3\u003e\n\u003cp\u003eField wiring connects to the 1771-WA field wiring arm, enabling slot insertion and removal without disconnecting external field leads. The module supports direct connection to DC input modules (such as the 1771-IC) when sharing a common DC power source to maintain matching ground potentials across control loops.\u003c\/p\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What size wire is recommended for the 1771-WA wiring arm? A: Use 14 to 22 AWG stranded copper wire rated at 75 deg C or higher, adhering to a 7 to 9 lb-in terminal screw torque limit.\u003c\/p\u003e\n\u003cp\u003eQ: Can an output on the 1771-OC directly drive a 48 VDC input module? A: Yes, it can directly drive a 1771-IC 48 VDC input module, provided both modules share the exact same DC power supply to prevent ground potential differences.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53212507341080,"sku":"1771-OC","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1771-OWN_Cocoai_1_89c8a058-d94f-44b0-98bc-7e02d003d72c.jpg?v=1794277189","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1771-oc-plc-5-digital-dc-output-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
