Product Overview

The Omron NX-PF0730 is the NX-series I/O power feed unit, manufactured by Omron Corporation. Hengyixin Automation stocks this controller option board in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.

It injects a fresh 5 to 24 VDC power segment into an NX I/O rack at up to 10 A. The unit carries 4 IOV (V+) terminals and 4 IOG (V-) terminals on a detachable screwless push-in terminal block. The IOG terminals are internally bridged so the cable lands once and feeds the downstream segment.

Use it to break a long NX rack into separate I/O power segments so the downstream units do not share the CPU or Coupler Unit's I/O power budget. The body is 104.5 x 12 x 80.1 mm and weighs 65 g. Siblings are the NX-PF0630 (6 A) and the NX-PD1000 system PSU. For CP1L expansion look at the CP1W-EXT01.

Key Features

  • NX-series I/O power feed unit with screwless push-in connector and detachable 8-position terminal block, 12 mm wide
  • 5 to 24 VDC input, 10 A output current, 4 IOV (V+) terminals and 4 IOG (V-) terminals internally bridged
  • Inserts a fresh 24 VDC segment into a long NX I/O rack so downstream units do not share upstream I/O power budget
  • IP20, 104.5 (H) x 12 (W) x 80.1 (D) mm, 65 g, DIN-rail mount, CE and cULus approvals
  • SKU: NX-PF0730
  • Series: NX-series machine automation I/O, system unit family (NX-PF)
  • Voltage: 5 TO 24 VDC

Best-Fit Applications

  • Mid-rack I/O power feed on a 12-unit NX slice line where the upstream CPU budget is exhausted and a second 24 VDC segment is needed
  • Spare segment for a Sysmac NJ501 EtherCAT rack where the original NX-PF0730 was lost during a maintenance swap and the downstream NX-OD4256 needs isolated power
  • Spare replacement for a CJ1W-PA202 retrofit where the new NX rack needs an NX-PF0730 to share the same 24 VDC cabinet feed

Buying Checklist

  • Pick the NX-PF0730 when 10 A of fresh I/O power is needed in an NX rack segment and 12 mm of DIN width is acceptable.
  • Pick the NX-PF0630 instead when the segment only needs 6 A of I/O power and the same 12 mm form factor is preferred.
  • Pick the NX-PD1000 instead when the rack needs a dedicated 24 VDC system power supply feeding the NX bus itself, not just the I/O segment.

FAQ for NX-PF0730

What is the Omron NX-PF0730 used for?
It is the NX-series I/O power feed unit. It injects a fresh 5 to 24 VDC segment into a long NX I/O rack at up to 10 A, so downstream NX units do not share the upstream CPU or Coupler Unit's I/O power budget. Typical uses are mid-rack I/O power segments on a 12-unit slice line, spare segments on a Sysmac NJ501 EtherCAT rack, and CJ1W-PA202 retrofits that need to add isolated 24 VDC to a new NX rack.
NX-PF0730 vs NX-PF0630 - what is the difference?
Both are 12 mm wide NX I/O power feed units with the same terminal layout. The NX-PF0730 supplies up to 10 A; the NX-PF0630 supplies up to 6 A. Pick the NX-PF0730 when the downstream segment has high-current outputs (NX-OD4121 PNP at 0.5 A per point) or a stack of analog units; pick the NX-PF0630 when the segment only has a few low-current slices.
Does the NX-PF0730 supply the NX bus itself?
No. The NX-PF0730 supplies the I/O power segment only (4 IOV and 4 IOG terminals). The NX bus power is supplied by the System Unit such as the NX-PD1000. Use the NX-PF0730 to add a fresh I/O power segment; use the NX-PD1000 or NX-PF0630 if you also need to feed the NX bus itself.
