756-PA75-B Power module

Description

The 1756-PA75-B is a standard power module primarily used to provide the necessary backplane power for the ControlLogix chassis.
This power module is installed in a dedicated power socket, usually on the far left side of the ControlLogix case.
Here are some of the main features and specifications of the 1756-PA75-B:
Protection: If the working input power supply is suddenly interrupted, this standard power supply will provide a limited hold time, depending on the input voltage. For example, it is 2 cycles at 85 V AC, 6 cycles at 120 V AC, and 20 cycles at 220 V AC.
Isolation and safety: The power supply has a 250 V (continuous) isolation voltage, enhanced insulation type, from the power input to the backplane. In addition, it was tested at 3500 V DC for 60 seconds.
Purpose: The main purpose of the PSU is to provide the backplane power supply for each module installed in the chassis to make it run.
Compatibility: The 1756-PA75-B is compatible with a variety of ControlLogix cases, such as 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17, etc., especially B Series and C Series cases.
Power Specifications: The power module is compatible with a voltage range of 85-264 VAC and a frequency of 47-63 Hz. Nominal input voltage is 120 VAC / 240 VAC. At 0… +60 °C (+32… At +140 °F), its rated output power is 75 W.
Current capacity: At 3.3 VDC, the current capacity of the power supply is 4 A; 13 A at 5.1 VDC; It is 2.8 A at 24 VDC.
Installation and configuration: The 1756-PA75-B must be installed on the left side of the ControlLogix case and comes with a non-replaceable fuse designed to prevent fire hazards caused by short circuits. In addition, it requires hardware configuration.
