Wired connection
Imagine the controller as your personal laptop. Connect it to the internet by plugging in a live Ethernet cable from your local network.
Simply insert the Ethernet cable into the Network socket of the controller and you are now connected to the Internet.
- No extra hardware cost – All network components embedded.
- No annual subscription fee.
Seamless, stable solution with reliable internet connection.
Wireless connection using a router
Connect your controller through a compatible 4G or 5G wireless router.
Install our router within the controller’s cabinet and use a sim-card from a local Internet provider to establish a web connection.
- Seamless and stable solution, ensuring a reliable internet connection.
- Wireless router installation required.
- Annual sim-card subscription applies.
Wireless connection
If you have an active router on site, you can use your CHEMTROL® controller to establish an internet connection.
In order to use this option our WIFI electronics module has to be installed. The controller then communicates with the router using the exiting username and password.
- WIFI electronics module installation required.
- No annual fee subscription.
- Check WIFI connectivity reception on-site.
Shared wireless access & control
A unique feature enabling multiple controllers in close proximity to share a WIFI signal. With this, a single Sim-card subscription connects all controllers, offering full connectivity and control.
Here’s how it works: The main controller, connected to a 4G or 5G wireless router, accesses the internet. Other controllers nearby use a WiFi device to piggyback on the main controller’s WiFi signal.
This allows adding multiple controllers without the cost of multiple subscriptions.
- Main controller: Wireless router installation required.
- Secondary controller: WIFI electronics module installation required.
- Annual sim-card subscription applies only to the main controller/wireless router.
- Seamless and stable solution with a reliable internet connection.
- No annual sim-card subscription for secondary controllers.
4–20 mA Output Module
The CHEMTROL® controller can be equipped with an optional 4–20 mA analog output module, allowing seamless integration with external control and monitoring systems.
This module enables real-time transmission of sensor measurements (such as pH, chlorine, conductivity, and other parameters) directly to:
- PLC systems
- SCADA platforms
- Building Management Systems (BMS)
- Remote monitoring systems
The 4–20 mA signal is the industry-standard method for reliable, long-distance analog communication in industrial environments, ensuring accurate and stable data transfer.
This option is ideal for facilities requiring centralized monitoring, automation integration, or compliance reporting.
Building Management System (BMS) and SCADA communication protocols
The CHEMTROL® programmable controller range is adaptable for communication using various open protocol languages.
The most commonly used protocols include:
- Modbus IP, Modbus RTU
- BACnet IP, BACnet MSTP
- LonWorks
The controller can be configured to operate with any of the above communication protocols. To enable this functionality, a dedicated BMS electronics module must be installed inside the controller cabinet.
This smart module converts the controller’s internal digital signals into the selected protocol language, allowing seamless integration with PLC, SCADA, or Building Management Systems (BMS).
