Product Overview
The Omron CP1W-MAD42 is a mixed analog I/O expansion unit for the CP1-series compact PLCs, 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 adds 4 analog inputs and 2 analog outputs to a CP1L, CP1H, CP1E N-series, or CP2E CPU via the CP1W expansion bus. Each channel supports -10 to 10 V, 0 to 10 V, 0 to 5 V, 1 to 5 V, 0 to 20 mA, and 4 to 20 mA ranges. Resolution is 1/12000 (full scale) on every input and output. Conversion takes 1 ms per point, or 6 ms for all six points.
Photocoupler isolation separates the analog terminals from the internal logic. For a matched 4-in / 4-out analog combo, pick the CP1W-MAD44. For analog input only, pick the CP1W-AD042. For analog output only, pick the CP1W-DA021. Configuration runs in CX-Programmer under the CX-One suite; no extra option board is needed.
Key Features
- 4 analog inputs and 2 analog outputs in one CP1W expansion module, voltage and current ranges per channel
- 14-bit resolution (1/12000 full scale), 1 ms per point conversion time, overall accuracy 0.3 percent at 25 C
- Photocoupler isolation between analog terminals and internal logic, 18-point detachable M3 screw terminal block
- Compatible with CP1L, CP1H, CP1E N-series, and CP2E N-series CPUs that accept CP1W expansion I/O
- SKU: CP1W-MAD42
- Series: CP1W-series analog I/O expansion units for the CP1 compact PLC family
Best-Fit Applications
- Temperature and pressure loop on a CP1L-EM30DT1-D driven by four Pt100-to-4-20 mA transmitters wired into the four CP1W-MAD42 inputs
- Speed reference on a packaging line where two CP1W-MAD42 outputs command variable-frequency drives with 4-20 mA setpoints updated every 100 ms
- Spare replacement on a water-treatment skid where the original CP1W-AD042 + CP1W-DA021 pair is replaced by one CP1W-MAD42 to save panel space
Buying Checklist
- Pick the CP1W-MAD42 for a 4-input / 2-output mixed analog I/O expansion on a CP1L, CP1H, CP1E N, or CP2E N CPU.
- Pick the CP1W-MAD44 instead when the cell needs 4 analog inputs and 4 analog outputs in one module on the same CP1W bus.
- Pick the CP1W-AD042 + CP1W-DA021 pair instead when the cabinet needs input-only and output-only modules in separate slots for serviceability.

FAQ for CP1W-MAD42
What is the Omron CP1W-MAD42 used for?
It is a mixed analog I/O expansion module for the CP1-series compact PLCs. It adds 4 analog inputs and 2 analog outputs to a CP1L, CP1H, CP1E N, or CP2E CPU via the CP1W expansion bus. Each channel accepts voltage or current signals at 14-bit resolution and updates in 1 ms per point. Typical uses are temperature and pressure loops, variable-frequency drive references, and load-cell weighing with a 4-20 mA transmitter.
CP1W-MAD42 vs CP1W-MAD44 - what is the difference?
Both are CP1W mixed analog I/O expansion modules with 14-bit resolution and the same voltage and current ranges. The -MAD42 has 4 inputs and 2 outputs; the -MAD44 has 4 inputs and 4 outputs. Pick the -42 when the cabinet only needs 2 outputs; pick the -44 when 4 outputs are required on the same CP1W bus.
Does the CP1W-MAD42 work with the CP1E E-series CPUs?
No. The CP1E E-series (economy) does not support CP1W expansion I/O. The CP1W-MAD42 works with the CP1E N-series (standard), the CP1L, the CP1H, and the CP2E N-series. Pick a CP1E-NA20DR-A CPU with a CP1W option board if analog I/O is needed on an E-series panel.
Does the CP1W-MAD42 need an external power supply?
No. The CP1W-MAD42 draws its 5 VDC and 24 VDC from the CP1W expansion bus on the CPU Rack. The 24 V analog loop power for 4-20 mA transmitters must come from an external 24 VDC supply. No separate power terminal is needed for the module itself.
