FAQ
FAQ
Q1: What is the primary function of the 1756-PA75/B?
The 1756-PA75/B provides backplane power for ControlLogix chassis systems and installed modules.
Q2: What AC input range does the power supply support?
It supports 85…265V AC input power at 47…63 Hz.
Q3: What output capacities are available?
The unit provides 1.5A @ 1.2V DC, 4A @ 3.3V DC, 13A @ 5.1V DC, and 2.8A @ 24V DC with a total maximum output of 75W.
Q4: What are the physical dimensions of the module?
The dimensions are approximately 140 mm (H) × 112 mm (W) × 145 mm (D).
Q5: Where is the module installed in the chassis?
It mounts on the far left side of a 1756 ControlLogix chassis.
Q6: Does the 1756-PA75/B provide field 24V DC power?
No. The internal 24V DC output is intended for chassis backplane operation, not external field device power. PLC community discussions also confirm separate field power supplies are normally required.
Q7: What is the difference between the 1756-PA72 and 1756-PA75?
The 1756-PA75 provides higher 5.1V DC backplane current capacity (13A vs 10A) and higher overall chassis power capability.
Q8: Is the 1756-PA75/B still supported?
Yes. The 1756-PA75 family remains widely supported and commonly used in ControlLogix chassis systems.
