Product Overview

The Omron CP1W-30ET1 is a 30-point expansion I/O unit for the CP1E and CP1L PLC families, manufactured by Omron Corporation. Hengyixin Automation stocks this I/O expansion unit in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.

The unit adds 18 digital inputs (24 VDC) and 12 PNP sourcing transistor outputs (12-24 VDC, 0.3 A per point) on a removable terminal block. The ET1 suffix marks PNP sourcing (the ET suffix is NPN sinking). The module draws 5 V at 0.13 A from the CPU via the CP1W-CN811 I/O connecting cable.

Compatible CPUs are CP1E E30 / E40 / E60, N30 / N40 / N60 and NA20, plus all CP1L and CP1H. The body is 130 x 90 x 85 mm in a 30-point form factor. For a 20-point PNP I/O expansion, pick the CP1W-20EDT1. For a 40-point PNP I/O expansion, pick the CP1W-40EDT1. For 32 PNP-only outputs on the same width, pick the CP1W-32ET1.

Key Features

  • CP1W 30-point expansion I/O, 18 DC inputs + 12 PNP sourcing transistor outputs
  • PNP sourcing outputs at 12-24 VDC, 0.3 A per point, 0.5 ms ON delay
  • 5 V 0.13 A current consumption from the CPU via CP1W-CN811 cable
  • Compatible with CP1E E30/40/60 + N30/40/60 + NA20, CP1L and CP1H
  • SKU: CP1W-30ET1
  • Series: Omron CP1W-series expansion I/O unit
  • I/O: 30 I/O

Best-Fit Applications

  • Adding 30 PNP outputs to a CP1E-N30DR-A or CP1L-M30DR-A cell that has run out of CPU outputs for a new divert arm and stack light
  • Existing 30-point field replacement where the prior CP1W-30ET1 unit (PNP sourcing) has failed and the wiring colour code matches
  • Spare expansion module for a CP1H-X40DR-A cabinet where the new I/O needs to land on PNP sourcing outputs to drive 24 VDC indicator stacks

Buying Checklist

  • Pick the CP1W-30ET1 for a 30-point CP1W expansion I/O with 18 DC inputs and 12 PNP sourcing transistor outputs.
  • Pick the CP1W-20EDT1 instead when the cabinet only adds 20 points (12 in / 8 out) on the same PNP sourcing form factor.
  • Pick the CP1W-32ET1 instead when the cabinet needs 32 PNP sourcing outputs (no additional inputs).

FAQ for CP1W-30ET1

What is the difference between CP1W-30ET and CP1W-30ET1?
CP1W-30ET is NPN sinking (load on the high side). CP1W-30ET1 is PNP sourcing (load on the low side). The two are NOT interchangeable. Always match the output polarity to the field wiring; swapping ET for ET1 without rewiring will short 24 VDC to ground through the load.
Does the CP1W-30ET1 need a separate 24 VDC supply?
Yes. The transistor outputs need an external 24 VDC field power supply to drive the loads. The unit itself draws 5 V logic power from the CPU via the CP1W-CN811 I/O cable.
How many CP1W-30ET1 units can I add to one PLC?
Up to 3 CP1W expansion units total per CP1E N30 / N40 / N60 / NA20 or CP1L PLC. On the CP1H the limit is 7 CP1W expansion units (plus 2 CJ-series via the CP1W-EXT01 adapter). Mix and match 30ET1 with 20EDT1 and 40EDT1 in any combination.
