EL200 Mono & Multi-Channel Water Controller


The EL200 is a configurable water controller that can adapt to many different probes and configurations, mono or multi-channel, among pH, ORP, dissolved oxygen, conductivity, chlorine, turbidity, total suspended solid (TSS) and temperature.
A user-friendly interface can display all the values as well as graphs of the recorded measurements over the last 24 hours. A USB port allows to transfer the recorded measurement that may be imported to Excel for treatments or graphs. The USB port can also be used to save the configuration or to update the internal software. A web-based interface allows the control and the troubleshooting at distance with an internet browser on a computer, tablet or smart phone.

EL200 controller includes basically:

  • one Ph/ORP input
  • two 4-20 mA inputs for analogic probes (dissolved oxygen, chlorine turbidity)
  • one RS485 port for up to 4 digit probes (dissolved oxygen, turbidity, pH, ORP)
  • two 4-20 mA outputs
  • four relays contacts for high/low alarms, multiplexing or probe default
  • one RS232 port for Modbus communication or web serve with an Ethernet or Wi-Fi interface
  • one RS485 port for Modbus communication

one or two modules can be added for conductivity probe, additional 4-20 mA inputs or additional 4-20 mA outputs.

EL200 Controller With Probes

Designed for rugged environment with lightning protection

The EL200 controller is designed to be use outside if necessary thanks to an aluminum casted IP65 enclosure. Special protection against lightning are installed on each probe inputs as well as on the power input and communication ports. The touch screen is protected by an acid resistant protection film to assume a efficient long term protection.

Auto-cleaning probes

The EL200 delivers a free potential contact to drove solenoid value on compressed air to clean the probes equipped with air cleaning. The period and cleaning time are adjustable to adapt to different applications

User-Friendly Interface

The colour touch screen and intuitive interface available in 8 different languages (Chinese, English, French, Germen, Italian, Portuguese, Spanish, Turkish) makes very easy to test or configure the analyser. A number of test functions allows to test and troubleshoot each element of the controller to setup quickly a maintenance diagnostic. The complete configuration can be saved on a USB key and reload if necessary.
