The hardware establishes multi-channel output current generation across standard 0-20 mA and 4-20 mA industrial field control loops. Each channel offers complete channel-to-channel galvanic isolation, preventing ground loop potential differences and common-mode noise propagation between independent field circuits. The module interfaces directly with the ControlLogix backplane system for bus power distribution, module status monitoring, and deterministic command execution without requiring external signal isolation barriers for individual field loops.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1756-OF6CI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.60 lbs (0.27 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eControlLogix Single-Slot Standard Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e4.5 W (Backplane dependent)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e6 points individually isolated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal Range\u003c\/td\u003e\n\u003ctd\u003e0-20 mA \/ 4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Connector\u003c\/td\u003e\n\u003ctd\u003e20-Pin Removable Terminal Block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Configuration\u003c\/td\u003e\n\u003ctd\u003eChassis Mount (1756 ControlLogix I\/O Chassis)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRemovable Terminal Block\u003c\/td\u003e\n\u003ctd\u003e1756-TBSA or 1756-TBSH (20-Pin)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eControlLogix System Architecture \u0026amp; Backplane Protocol Features\u003c\/h3\u003e\n\u003cp\u003eThe module communicates over the local ControlLogix backplane bus utilizing high-velocity CIP (Common Industrial Protocol) framing. Backplane bus communication velocity guarantees low deterministic latency during field analog updates. High-density I\/O routing protocols ensure synchronous cyclic data transmission to the system controller, matching configured Requested Packet Interval (RPI) rates down to sub-millisecond thresholds. Firmware flash compatibility enables online maintenance through Studio 5000 Logix Designer without physically dismounting the chassis assembly.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1756-OF6CI module be removed or inserted under power (RIUP)?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module supports Removal and Insertion Under Power (RIUP) within ControlLogix chassis. However, external 24 VDC field loop power connected to the 20-pin Removable Terminal Block (RTB) should be de-energized prior to disconnecting the RTB connector to prevent unintended field actuator switching.\u003c\/p\u003e\n\u003cp\u003eQ: Does each channel on the 1756-OF6CI require a separate loop power source?\u003c\/p\u003e\n\u003cp\u003eA: Each channel features individual channel-to-channel galvanic isolation. Channels can be powered from independent external 24 VDC field supplies or shared power sources, provided channel continuous voltage differential limits are maintained within specified isolation boundaries.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure backplane chassis grounding complies with IEEE 1100 standards; ground wire connection to the enclosure star ground point must maintain low impedance using copper conductors.\u003c\/li\u003e\n\u003cli\u003eTorque standard 20-pin Removable Terminal Block (RTB) wiring terminals to manufacturer specifications to maintain solid low-resistance physical contact.\u003c\/li\u003e\n\u003cli\u003eMaintain dedicated wiring separation between analog current loop cables and high-voltage AC power lines inside system wiring trunks.\u003c\/li\u003e\n\u003cli\u003eUtilize twisted-pair shielded instrumentation cables for 4-20 mA signals, grounding the cable shield at a single cabinet point to minimize electromagnetic noise pickup.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48786277728446,"sku":"1756-OF6CI","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1756-OX8I_64566758-2814-423f-b0f7-a47d9af7e84b.png?v=1787710332","url":"https:\/\/www.autooiltech.com\/ar\/products\/allen-bradley-1756-of6ci-controllogix-analog-output-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
