OMRON NJ-PD3001 Power Supply Unit

Omron NJ‑PD3001 is a DC power supply unit for the Sysmac NJ‑series controller platform. Converts 24 V DC input to stable 5 V DC and 24 V DC outputs for the CPU rack. Provides 30 W total output capacity (5 V DC, 6.0 A; 24 V DC, 1.0 A). Features a RUN output contact (SPST‑NO) to monitor CPU operation status. Screw terminal block, DIN rail mounting. Designed exclusively for NJ‑series CPU racks and expansion racks.

Applications:

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

• 24 V DC powered automation cabinets and control panels

• Machine automation and industrial control systems

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