CCM223/LIQUISYS-M Spare Parts List Overview
The CCM223 and LIQUISYS-M series transmitters are widely used in water quality analysis applications such as pH, conductivity, chlorine, and oxygen. This article compiles the ordering information for commonly used spare parts and upgrade kits for this series, facilitating engineering maintenance and procurement selection.
All spare parts are divided by function into five major categories: relay output modules, main modules, terminal blocks, power supply and housing accessories, and software upgrade packages. The following sections explain the order numbers, specifications, and applicable scenarios for each category.
Relay Output Modules and Circuit Boards
Relay modules are used to expand the digital output capability of the LIQUISYS-M basic version. Common configurations include 2-channel or 4-channel floating changeover contacts, and some models also integrate 4-20mA current inputs.

| 51502498 | Kit CCM2X3 Main Module | Central module Profibus DP |
| 71134731 | Kit CCM2x3 Central Processing Unit | Central processing unit |
If HART or Profibus communication is used on site, please select the corresponding model with the appropriate protocol to avoid communication incompatibility.
Terminal Blocks and Connection Kits
Terminal block kits are used to match different signal types and communication protocols, ensuring reliable wiring and interference resistance.
- 51502463: Kit CCM223 Terminal Block, mA + HART
- 51502490: Kit CCM223 Terminal Block, Profibus DP
- 51502464: Kit CCM223 Terminal Block, Profibus PA
- 51501078: KIT CXM223 Terminal Block
When purchasing, please verify that the transmitter communication protocol matches the terminal block model to prevent signal mismatch.
Power Supply, Housing, and Mechanical Accessories
Power supply and housing accessories are used for powering and installing the transmitter, including AC/DC power supply kits, housing components, side panels, bottom covers, and mounting brackets.
Power Supply and Housing Accessories List
| Order Number | Name | Specification Description |
|---|---|---|
| 51500317 | CXM2X3 AC Power Supply | KIT CXM2X3 power supply AC |
| 51500318 | CXM2X3 DC Power Supply | KIT CxM2x3 power supply DC |
| 51501075 | CXM223 Housing Accessories | Kit CXM223 housing assembly |
| 51501076 | CXM223 Mechanical Housing Parts | KIT CXM223 Mechanical housing parts |
| 51502124 | CXM223 Side Panel | Kit CXM223 side wall |
| 51502513 | CXM223 Profibus DP Bottom Cover | Kit CXM223 End frame Profibus DP |
| 71071440 | Kit CxM223 Front Panel | Front foil + 6 key lifters |
| 50047795 | Housing Mounting Bracket | For fixed housing installation |
Mounting brackets and housing accessories should be selected according to the on-site installation method to ensure protection rating and mechanical strength meet requirements.
Transmitters and Upgrade Software Packages
In addition to hardware spare parts, LIQUISYS-M also offers various software upgrade packages to expand measurement parameters and functions.
Transmitter Kits
- 51502466: KIT MKC1 MEK Transmitter Cl wo pH non Ex
- 51502465: Kit MKC1 MEK Transmitter Cl+pH non Ex
Upgrade Software Packages
- 51500385: Extended software upgrade package, upgrades LIQUISYS-M basic version to S version (plus-package), supports pH, conductivity, temperature, chlorine, oxygen, and other parameters. Instrument serial number required.
- 51500963: Cleaning function upgrade package (Chemoclean), instrument serial number required; if the 4-relay board is not yet installed, 51500321 must be ordered separately.
- 51502460: pH measurement upgrade package, used to upgrade basic version Liquisys S CCM2X3-EK to pH or ORP measurement. Instrument serial number required.
- 51503526: pH measurement upgrade package, used to upgrade Liquisys S CCM2X3-ES to pH or ORP measurement.
When ordering upgrade packages, the instrument serial number must be provided to ensure software and hardware version compatibility.
Selection and Procurement Notes
- Confirm the transmitter basic version and hardware version, especially the Profibus DP module which requires hardware 2.10 or higher.
- Select the corresponding main module and terminal block according to the communication protocol to avoid mixing HART, Profibus PA/DP.
- Upgrade software packages require the instrument serial number; some upgrades require additional ordering of the relay board.
- Power supply kits are divided into AC and DC; please verify the on-site power supply method when purchasing.
- Housing and mounting accessories must match the on-site installation conditions to ensure the protection rating.
The above spare parts list can serve as a quick reference for maintenance and expansion of CCM223/LIQUISYS-M transmitters. It is recommended to confirm compatibility with the latest official documentation.
