EL200
Mono & Muti-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, UV254, Ammonia, dissolved oxygen, conductivity, chlorine, turbidity, total suspended solids (TSS) and temperature.
It includes by default:- one pH/ORP input
- two 4-20 mA inputs for analogic probes (chlorine, turbidity)
- one RS485 port for up to 4 digital probes (dissolved oxygen, turbidity, UV254, Ammonia, TSS).
- two 4-20 mA outputs
- four relays contacts for high/low alarms, multiplexing or probe default
- one RS232 port for Modbus communication or web server with an Ethernet or Wi-Fi interface
- one RS485 port for Modbus communication
Key Features
- Multichannel : Up to 7 probes connected in single EL200
- 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 measurements 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.
- The EL200 controller is designed to be used outside if necessary, thanks to an aluminium casted 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 ensure an efficient long term protection.
