1746-P1 Advantages
The Allen‑Bradley 1746-P1 Power Supply Module stands out from comparable PLC power supplies in several key areas.
Auto-ranging 120/240V AC input design. The Allen‑Bradley 1746-P1 Power Supply Module supports automatic AC voltage range selection, adapting to different mains voltage standards in various countries and regions without manual jumper adjustment.
5A 5V DC high capacity backplane output. The Allen‑Bradley 1746-P1 Power Supply Module provides up to 5A 5V DC backplane current, enough to support a full complement of SLC‑500 I/O and communication modules in the chassis.
Built-in multi-layer fault protection. The Allen‑Bradley 1746-P1 Power Supply Module integrates overvoltage, overcurrent and short-circuit protection functions, cutting off power output automatically when faults occur to protect the SLC‑500 CPU and other modules on the backplane.
Native Allen‑Bradley SLC‑500 system integration. As a factory‑original SLC‑500 series component, the Allen‑Bradley 1746-P1 Power Supply Module can be directly inserted into any standard SLC‑500 chassis slot without conversion adapters or mechanical modification.
Power status visual indication. The Allen‑Bradley 1746-P1 Power Supply Module is equipped with power OK indicator light for quick visual judgment of power supply health status during commissioning and routine maintenance.
Compact form factor matching SLC rack layout. The Allen‑Bradley 1746-P1 Power Supply Module adopts the same form factor as other SLC‑500 I/O modules, occupying only one slot of the chassis and keeping cabinet layout neat and unified.
