As operating temperatures rise toward the maximum limit of 60 °C (140 °F), continuous current ratings undergo a linear derating down to 1 A per point and 4 A total per module to protect internal circuitry from overheating. Total module current is capped at a maximum of 5 A at 30 °C.\u003c\/p\u003e\n\u003ch3\u003eWiring and Termination\u003c\/h3\u003e\n\u003cp\u003eField side connections are established via compatible Removable Terminal Blocks (RTB), specifically the \u003cstrong\u003e1756-TBCH\u003c\/strong\u003e or \u003cstrong\u003e1756-TBS6H\u003c\/strong\u003e. Because the sixteen outputs are individually isolated, each channel can interface with independent AC load circuits operating at separate phases or potential levels, provided they remain within the 74–265 VAC operational threshold.\u003c\/p\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: Can the 1756-OA16I module drive inductive loads such as AC solenoids and motor starters? A: Yes, AC output modules can drive inductive loads, but appropriate surge suppressors (such as MOV or RC networks) should be installed across inductive device terminals to limit voltage transients and extend contact life.\u003c\/p\u003e\n\u003cp\u003eQ: Are the 16 output channels sharing a common return? A: No, the 1756-OA16I features sixteen individually isolated outputs, meaning each point has dedicated isolated terminals allowing connection to completely separate AC supply circuits.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":53255974715672,"sku":"1756-OA16I","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1756-OX8I_1__Cocoai_2716ae19-00e2-45b7-9db9-ace340079bba.jpg?v=1794448125","url":"https:\/\/www.innoplcsync.com\/products\/output-module-allen-bradley-1756-oa16i","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
