Allen-Bradley 1746-P2 SLC-500 PLC Processor Module

The Allen‑Bradley 1746-P2 is a SLC‑500 modular power supply for Allen‑Bradley 1746 backplanes, converting 120/240 VAC input to the DC rails that power the CPU and I/O modules in an SLC‑500 chassis. It accepts 120/240 VAC input at 50/60 Hz and delivers 24 V DC backplane power capable of up to about 70 watts of continuous output. The module provides two backplane rails: a 5 V rail rated to supply up to 5 A and a 24 V rail capable of about 0.96 A, supporting typical SLC‑500 configurations that include CPUs and I/O modules such as the 1746‑IB16. The P2 is a compact, rack‑mount power supply with dimensions roughly 5.5 in x 2.9 in x 5.7 in and an inrush current around 20 A, suitable for use in 10‑slot or larger 1746 chassis. It is designed to operate within standard room temperatures and is part of the Series 1 1746 family of SLC‑500 components, providing a reliable source of backplane power for automation tasks ranging from simple I/O to multi‑module control schemes.
