This module is engineered to provide reliable power to the chassis backplane, converting an 18-32V DC input into the necessary logic voltages (1.2V, 3.3V, 5.1V, and 24V DC) required by ControlLogix I\/O and processor modules. With a maximum output power rating of 75W, it is capable of supporting fully populated chassis configurations in demanding industrial environments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e75W maximum output power at 60 degC.\u003c\/li\u003e\n\u003cli\u003eDesigned for dedicated mounting on the far-left slot of a 1756 chassis.\u003c\/li\u003e\n\u003cli\u003eWide input voltage range: 18-32V DC (24V DC nominal).\u003c\/li\u003e\n\u003cli\u003eIntegrated overcurrent and overvoltage protection for backplane safety.\u003c\/li\u003e\n\u003cli\u003e250V continuous galvanic isolation between the power source and backplane logic.\u003c\/li\u003e\n\u003cli\u003eCompatible with standard 1756 Series B and C chassis (1756-A4, A7, A10, A13, A17).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Model\u003c\/td\u003e\n\u003ctd\u003e1756-PB75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eStandard DC Power Supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24V DC (Nominal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Range\u003c\/td\u003e\n\u003ctd\u003e18-32V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Power\u003c\/td\u003e\n\u003ctd\u003e75W at 60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Power\u003c\/td\u003e\n\u003ctd\u003e95W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eControlLogix Chassis (Leftmost Slot)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.98 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWater and Wastewater Treatment: Powering controllers for dosing pumps and flow valves.\u003c\/li\u003e\n\u003cli\u003eFood and Beverage Production: Supporting automation for pasteurization and bottling lines.\u003c\/li\u003e\n\u003cli\u003eChemical and Petrochemical: Providing stable power for high-precision PID control loops.\u003c\/li\u003e\n\u003cli\u003eHVAC and Climate Control: Managing industrial cooling towers and damper systems.\u003c\/li\u003e\n\u003cli\u003eMetals and Mining: Supporting hydraulic press control and position monitoring.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the power supply is installed in the dedicated leftmost slot of the 1756 chassis.\u003c\/li\u003e\n\u003cli\u003eAlways disconnect the main power source before inserting or removing the module from the chassis.\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding of the chassis to minimize EMI and protect against electrical surges.\u003c\/li\u003e\n\u003cli\u003eMaintain adequate clearance around the chassis to allow for proper airflow and cooling, as the unit is rated for operation up to 60 degC.\u003c\/li\u003e\n\u003cli\u003eUse appropriately sized wiring for the 24V DC input to prevent voltage drop.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch3\u003eWhat is the difference between the 1756-PA75 and 1756-PB75?\u003c\/h3\u003e\n\u003cp\u003eThe 1756-PA75 is designed for AC power input (85-264V AC), whereas the 1756-PB75 is designed for DC power input (18-32V DC).\u003c\/p\u003e\n\u003ch3\u003eWhich chassis are compatible with this power supply?\u003c\/h3\u003e\n\u003cp\u003eThe 1756-PB75 is compatible with standard 1756 Series B and C chassis, including models 1756-A4, A7, A10, A13, and A17.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":50827420958972,"sku":"1756-PB75","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_74e24911-3a62-460a-b537-be8d42c0d122.jpg?v=1785545079","url":"https:\/\/www.electronicplc.com\/es\/products\/allen-bradley-1756-pb75-dc-power-supply","provider":"Electronic PLC","version":"1.0","type":"link"}
