Product Overview
The Omron CP1W-40EDT1 is a 40-point digital I/O expansion unit for the CP1 series PLC platform, 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 24 DC inputs (24 VDC, PNP or NPN configurable) and 16 PNP sourcing transistor outputs (0.3 A per point, 4.5 to 30 VDC permitted) to a CP1E, CP1L, or CP1H CPU. Input ON/OFF response is configurable from 0 to 32 ms in CX-Programmer; output ON response is 0.1 ms and OFF is 1 ms. Screw terminal block. The unit draws 0.16 A on the 5 VDC CP1 expansion bus and needs no external 24 V supply.
Up to three CP1W expansion units chain to the right of the CPU on the same bus; a CP1H host allows 160 I/O points maximum. The CP1W-40EDR sibling is the relay-output version of the same 24/16 body; the CP1W-20EDT1 is the 12-in / 8-out half-size.
Key Features
- CP1-series digital I/O expansion unit, 24 DC inputs (PNP / NPN configurable) and 16 PNP sourcing transistor outputs
- 0.3 A per output at 4.5 to 30 VDC, 0.1 ms ON / 1 ms OFF output response, photocoupler isolation, screw terminal block
- 0 to 32 ms configurable input filter via CX-Programmer, 20.4 to 26.4 VDC permitted input voltage, ON 14.4 VDC / OFF 5.0 VDC
- Bus-powered from the CP1E, CP1L, or CP1H CPU on 5 VDC 0.16 A; up to 3 units chain to 160 I/O points max on a CP1H host
- SKU: CP1W-40EDT1
- Series: Omron CP1-series digital I/O expansion (CP1W bus)
- Voltage: 20.4 TO 26.4 VDC
Best-Fit Applications
- I/O expansion on a CP1L-EM30DT-D controlled packaging machine that needs 24 sensor inputs and 16 solenoid outputs beyond the CPU's 30 built-in points
- Spare replacement on a CP1H-X40DR-A panel that previously had two CP1W-40EDR relay modules and now needs a faster transistor-output module on the same bus
- Remote expansion on a long conveyor where the CP1W-CN811 extension cable carries the CP1W-40EDT1 up to 8 m from the CP1E-N30DT-D CPU
Buying Checklist
- Pick the CP1W-40EDT1 for a 24-in / 16-PNP-out digital expansion unit that bus-mounts on a CP1E, CP1L, or CP1H CPU.
- Pick the CP1W-40EDR instead when the same 24-in / 16-out body is needed with mechanical relay outputs at 2 A switching.
- Pick the CP1W-20EDT1 instead when the cabinet only needs 12 DC inputs and 8 PNP outputs on a tighter bus-mount unit.

FAQ for CP1W-40EDT1
What is the Omron CP1W-40EDT1 used for?
It is the 40-point digital I/O expansion unit for the CP1 series PLC platform. It adds 24 DC inputs and 16 PNP sourcing transistor outputs to a CP1E, CP1L, or CP1H CPU on the CP1 expansion bus without needing a separate 24 V supply.
CP1W-40EDT1 vs CP1W-40EDR - what is the difference?
Both have 24 DC inputs and 16 outputs in the same 150 x 90 x 50 mm body. The CP1W-40EDT1 has 16 PNP sourcing transistor outputs at 0.3 A and 0.1 ms ON response; the CP1W-40EDR has 16 mechanical relay outputs at 2 A with 10 ms switching. Pick the EDT1 for fast solenoid switching and the EDR for high-current AC loads.
Does the CP1W-40EDT1 need a separate power supply?
No. The CP1W-40EDT1 draws 0.16 A on the 5 VDC CP1 expansion bus from the host CPU. There is no separate 24 VDC power input on the CP1W-40EDT1; field devices are powered from the same 24 VDC supply that feeds the CPU's input terminals.
How many CP1W-40EDT1 units can connect to a CP1L?
A CP1L CPU hosts one CP1W expansion unit directly. If more I/O is needed, an additional CP1W unit can be chained off the first via the CP1W-CN811 extension cable, for up to two CP1W expansion units per CP1L. A CP1H CPU hosts up to three CP1W expansion units for 160 I/O points maximum.
What is the input filter range on the CP1W-40EDT1?
0 to 32 ms, configured per input in CX-Programmer under the PLC Setup. The default is 8 ms; bump it to 16 or 32 ms on noisy long-cable inputs to stop contact-bounce and EMI false triggers. The filter adds to a 16 ms hardware delay.
