Product Overview
The Omron NX-PF0630 is an Additional I/O Power Supply unit for the NX-series I/O bus, manufactured by Omron Corporation. Hengyixin Automation stocks this power supply in Xiamen and ships within 3-5 business days in original Omron packaging. Specifications on this page were checked against Omron's NX-series System Unit datasheet.
The unit injects extra current into the I/O power rail of an NX rack. Input voltage is 5 to 24 VDC (operating 4.5 to 28.8 VDC). The I/O power feed max current is 4 A. This raises the available I/O power above what the CPU or EtherCAT coupler can deliver, or splits the rack into two isolated power groups for E-stop zoning.
The screwless push-in 8-terminal connector takes two IOV (+) and two IOG (-) pairs plus through-wiring for the next unit. The 12 x 100 x 71 mm body weighs 65 g and slots onto the NX bus like any other NX unit. Operating temperature is 0 to 55 degC. For a 10 A version on the same body, pick the NX-PF0730. For the NX-bus (unit) power supply role, use NX-PD1000.
Key Features
- NX-series Additional I/O Power Supply unit, 5-24 VDC input
- I/O power feed up to 4 A, 4.5 to 28.8 VDC operating range
- Screwless push-in 8-terminal connector, 12 x 100 x 71 mm
- Splits the I/O power supply into two groups along the NX bus
- SKU: NX-PF0630
- Series: Omron NX-series System Unit (Additional I/O Power Supply)
- Voltage: 5 TO 24 VDC
- I/O: 4 I/O
Best-Fit Applications
- Splitting a 32-station NX I/O rack into a hot zone (24 V always on) and a cold zone (dropped on E-stop) without a second CPU
- Adding 4 A of I/O current to a CX-series NX-ECC201 coupler whose 4 A internal limit has been reached by the digital output modules
- Spare replacement on a machine retrofit where the original NX-PF0630 failed and the new unit drops onto the same DIN-rail slot with no rewiring
Buying Checklist
- Pick the NX-PF0630 for a 4 A I/O power feed on an NX rack with a screwless push-in connector.
- Pick the NX-PF0730 instead when the I/O power feed needs 10 A on the same body.
- Pick the NX-PD1000 instead when the unit needs to feed the NX-bus (unit) 5 VDC rail rather than the I/O 24 VDC rail.

FAQ for NX-PF0630
Where do I place the NX-PF0630 in the rack?
Anywhere after the CPU or EtherCAT coupler. The NX-PF0630 has no address of its own; it sits on the bus as a power unit. Place it between two I/O groups when you want to split the I/O power.
Does the NX-PF0630 add EtherCAT nodes?
No. The unit has no EtherCAT slave interface. It is invisible on the network configuration. The I/O modules on either side count as one rack on the network.
Can I parallel two NX-PF0630 units?
Not for current sharing on the same group. Use two NX-PF0630 units only when you want to split the rack into two isolated power groups.
