Providing channel-to-backplane isolation rated at 250 V continuous with reinforced insulation, the power supply isolates incoming 125 VDC field supply transients from sensitive backplane logic circuitry. Firmware flash compatibility across ControlLogix racks is supported while delivering multi-rail power outputs (1.2 VDC, 3.3 VDC, 5.1 VDC, and 24 VDC) necessary for high-density I\/O density scaling.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Where must the 1756-PH75 power supply be installed within a ControlLogix chassis?\u003c\/p\u003e\n\u003cp\u003eA: The 1756-PH75 must be installed exclusively in the dedicated power supply slot located on the far left side of compatible Series B ControlLogix chassis (such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, or 1756-A17).\u003c\/p\u003e\n\u003cp\u003eQ: What are the backplane current output capabilities for each voltage rail of the 1756-PH75?\u003c\/p\u003e\n\u003cp\u003eA: The module supplies maximum load-dependent currents of 1.5 A at 1.2 VDC, 4.0 A at 3.3 VDC, 13.0 A at 5.1 VDC, and 2.8 A at 24 VDC, up to a total combined maximum output power of 75 W at 60 deg C.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize the main 125 VDC supply line before mounting or wiring the power supply module.\u003c\/li\u003e\n\u003cli\u003eMount the 1756-PH75 directly into the leftmost position of the target ControlLogix chassis, ensuring top and bottom chassis latches engage fully.\u003c\/li\u003e\n\u003cli\u003eStrip 2.5 mm squared (14 AWG) stranded or solid copper wire with 90 deg C rated insulation for incoming DC power connections.\u003c\/li\u003e\n\u003cli\u003eTighten the power input screw terminals to a torque specification of 0.8 N m (7 lb in).\u003c\/li\u003e\n\u003cli\u003eVerify chassis grounding by connecting a dedicated low-impedance copper ground conductor from the enclosure earth point to the chassis grounding stud.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":48784600465598,"sku":"1756-PH75","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/1756-PH75_bd593c80-3478-43bc-9027-5fa07b36067c.png?v=1787650734","url":"https:\/\/www.autooiltech.com\/products\/allen-bradley-1756-ph75-controllogix-power-supply-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
