When selecting, confirm the number of contacts, whether current input is included, and the installation position to avoid conflicts with existing modules.
CCM2x3 Central Module and Main Module Kits
The central module is the core processing unit of the transmitter, and different communication protocols require corresponding kits. Below are the ordering numbers and specifications of main module kits.
| Ordering Number | Specification | Description |
|---|---|---|
| 51502467 | Kit CCM2x3 Central Module I1 | Basic central module |
| 51502497 | Kit CCM2x3 Central Module I1 HART | Supports HART communication |
| 51502468 | Kit CCM2x3 Central Module I2 | Enhanced central module |
| 51502496 | Kit CCM2x3 Central Module I2 HART | Supports HART communication |
| 51502495 | Kit CCM2X3 Central Module Profibus PA | Profibus PA protocol |
| 51502498 | Kit CCM2X3 Central Module Profibus DP | Profibus DP protocol |
| 71134731 | Kit CCM2x3 Central Processor | Central processor unit |
When selecting the central module, determine the model based on the fieldbus type (HART, Profibus PA/DP) and I/O requirements.
Power Supply and Transmitter Kits
Power supply kits provide stable power to the transmitter, while transmitter kits are used to connect pH, chlorine, and other sensors.
- 51500317: CXM2X3 AC power supply kit, suitable for AC power supply applications.
- 51500318: CXM2X3 DC power supply kit, suitable for DC power supply applications.
- 51502466: KIT MKC1 MEK transmitter, Cl without pH, non-explosion-proof.
- 51502465: Kit MKC1 MEK transmitter, Cl+pH, non-explosion-proof.
- 71134732: Relay module, including 1 Profibus DP relay module, 2 relays, 1 current input DP connection, compliant with H/W 2.10 standard.
Power supply selection must match the on-site power supply system, and transmitter kits should be selected based on measurement parameters (such as residual chlorine, pH).
CXM253 Housing and Installation Accessories
Housing and installation accessories are used for mechanical installation and protection of the transmitter, ensuring reliable on-site operation.
- 51501068: KIT CXM253 instrument panel, kit CXM253 housing cover.
- 71071446: Kit CxM253 front foil + 6 key lifters.
- 51501073: CXM253 internal mounting parts, KIT CXM253 internal housing parts.
- 51502184: Transmitter connection head.
- 51501072: CXM253 mounting base plate, kit CXM253 housing bottom.
- 51501069: Mounting hinge, kit hinge.
- 51501079: CXM223 terminal block power supply, KIT CXM253 terminal block power supply.
- 51501074: CXM253 flat cable, KIT CXM253 ribbon cable.
- 50086842: LIQUISYS transmitter column mounting part, used to install the field transmitter on horizontal or vertical pipes (maximum diameter 60mm), material is stainless steel V2A.
Installation accessory selection requires confirmation of pipe diameter, material, and protection class requirements.
Software Upgrade Packages and Function Expansion
Upgrade packages can expand the functions of the LIQUISYS-M basic version, such as adding measurement parameters, cleaning functions, etc. Upgrades usually require the instrument serial number.
- 51500385: Extended software upgrade package, upgrades LIQUISYS-M basic version to S version (plus-package), supports pH, conductivity, temperature, chlorine, oxygen, and other parameters (WX to WS). Instrument serial number required.
- 51500963: Cleaning function upgrade package, adds Chemoclean cleaning function to LIQUISYS-M basic version. Instrument serial number required. If the 4-relay board is not installed, order 51500321 separately.
- 51502460: pH measurement upgrade package, used to upgrade the basic version Liquisys S CCM2X3-EK to pH or ORP measurement and add additional functions. Order must include instrument serial number.
- 51503526: pH measurement upgrade package, used to upgrade Liquisys S CCM2X3-ES to pH or ORP measurement and add additional functions.
Before upgrading, confirm the current instrument version and hardware configuration, and install the required relay board first if necessary.
Selection and Ordering Precautions
To ensure correct matching of spare parts, please pay attention to the following points when ordering:
- Confirm the transmitter model and version (e.g., LIQUISYS-M basic version, S version).
- Verify the communication protocol (HART, Profibus PA/DP) and central module model.
- Check the number of relay contacts and whether current input is required.
- Software upgrade packages require the instrument serial number.
- Installation accessories must match pipe size and material.
It is recommended to keep a complete ordering number list for future maintenance and procurement.
