Product Overview

The Omron CP1W-20EDT1 is a 20-point I/O expansion unit for the CP1E, CP1L and CP1H PLC families It is 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. Specifications on this page were checked against Omron's CP-series I/O Unit documentation.

The unit adds 12 24 VDC inputs and 8 PNP (sourcing) transistor outputs to a CP1-series CPU. Inputs are 24 VDC +10/-15 percent with 5 mA typical input current.

For a 20-point expansion with NPN (sinking) outputs instead, pick the CP1W-20EDT. Key specs: I/O Points 20 points total: 12 inputs + 8 outputs; Input Voltage / Current 24 VDC +10/-15%; 5 mA typical; Input ON / OFF Delay 0 to 32 ms (default 8 ms); Output Type PNP (sourcing) transistor, 4.5-30 VDC; Output Rating 0.3 A per point, 0.9 A per common; Output ON / OFF Delay 0.1 ms max ON / 1 ms max OFF; Connector Fixed screw terminal block (not removable), M3 screws - Omron's CP-series catalogue specifies a fixed block for this unit; Compatible CPUs CP1E N30/N40/N60/NA20, CP1L, CP1H, CP2E.

Key Features

  • CP1W 20-point I/O expansion: 12 24 VDC inputs + 8 PNP (sourcing) transistor outputs
  • Outputs 4.5 to 30 VDC at 0.3 A per point, 0.9 A per common, 0.1 ms ON delay
  • Screw terminal block, 5 V supplied from the backplane bus, 86 x 90 x 50 mm, 300 g
  • Compatible with CP1E N30 / N40 / N60 / NA20, CP1L, CP1H and CP2E CPUs
  • SKU: CP1W-20EDT1
  • Series: Omron CP1W-series Expansion I/O Unit
  • Voltage: 24 VDC
  • I/O: 20 points

Best-Fit Applications

  • Mid-size packaging line where the CP1L CPU is wired to PNP sensors and needs 12 inputs plus 8 sourcing outputs
  • European-style cabinet where the field wiring is PNP and the existing expansion is CP1W-20EDT, ready to swap to PNP
  • Conveyor control panel using a CP1W-20EDT1 plus a CP1W-8ET1 output unit for the diverter solenoids

Buying Checklist

  • Pick the CP1W-20EDT1 for a 20-point CP1W expansion with PNP (sourcing) transistor outputs.
  • Pick the CP1W-20EDT instead when the cabinet calls for NPN (sinking) outputs to match an NPN sensor field.
  • Pick the CP1W-20EDR1 instead when the load is a relay coil or a small solenoid and contact outputs are wanted.

FAQ for CP1W-20EDT1

What is the difference between CP1W-20EDT1 and CP1W-20EDT?
The CP1W-20EDT1 has PNP (sourcing) outputs and the CP1W-20EDT has NPN (sinking) outputs. Both have 12 24 VDC inputs and 8 0.3 A outputs. Pick the output polarity that matches the field wiring.
How many CP1W-20EDT1 units can a CP1L CPU host?
Up to three CP1W expansion units in total on a CP1L CPU. The CP1L CPU also allows one CJ-series Special I/O or CPU Bus Unit through the CP1W-EXT01 adapter.
Does the CP1W-20EDT1 need a separate 24 VDC supply?
Inputs and outputs share the field 24 VDC. The unit's 5 V logic comes from the CP1-series backplane; the unit does not draw 24 V from the bus.
