If you use this module with a DC load, the output will turn on but will stay \"latched\" on indefinitely, potentially damaging the module or the connected equipment. Use a 1734-OB or 1734-OV module for DC applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this module require a specific keyswitch position on the terminal base?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. You must set the terminal base keyswitch to the correct position specified in the 1734-OA4 installation manual (typically Position 8 for AC modules) to prevent the accidental insertion of low-voltage DC modules into a high-voltage AC wired base.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many outputs can I use at full capacity simultaneously?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach channel supports up to 0.75 A, but you must ensure the total module current does not exceed the thermal dissipation limits of your specific cabinet configuration. Always verify the aggregate current draw against the POINT I\/O power supply capacity.\u003c\/p\u003e","brand":"Allen Bradley","offers":[{"title":"Default Title","offer_id":43353711018074,"sku":"1734-OA4","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/485._77f82d59-26e6-4ccb-8053-cca56670fa05.jpg?v=1778571404","url":"https:\/\/www.spareoil.com\/products\/digital-ac-output-module-brand-new-allen-bradley-1734-oa4","provider":"SpareOil Automation","version":"1.0","type":"link"}
