Question

Answer

What is the purpose of the 1756-PSCA2?

It is the interface between the redundant power supplies and the chassis. It receives power from one or two external power supplies (like the 1756-PA75R or 1756-PB75R) and delivers it to the chassis backplane through a single connection .

Can I mix AC and DC power supplies with this adapter?

Yes, the redundant power supply system allows you to mix or match AC (e.g., 1756-PA75R) and DC (e.g., 1756-PB75R) power supplies when used in tandem with the 1756-PSCA2.

Does the 1756-PSCA2 require its own power source?

No. It is a passive device. It does not have its own power input and does not consume power to operate. It simply channels power from the connected redundant supplies to the chassis.
