Omron NJ-PA3001 NJ Series Power Supply Unit 100-240V AC 30W DIN Rail

Omron NJ‑PA3001 is a wide‑range AC power supply unit for NJ‑series and DX‑series machine automation controllers. Mounts to the left of the CPU unit on the CPU rack (first slot). Converts 100‑240 V AC input to regulated 5 V DC (6.0 A) and 24 V DC (1.0 A) backplane power, 30 W total output. Provides a RUN output contact (SPST‑NO) for external monitoring of CPU operation status. Screw terminal block. DIN rail mounting.

Applications:

• Rack power supply for Omron NJ‑series CPU racks and expansion racks

• 100‑240 V AC powered automation cabinets and control panels

• Machine automation and industrial control systems

• Power distribution for NJ‑series I/O and special units

• DX‑series controller racks
