RS485 Modbus MODBUS RTU Single Channel Digital Intelligent PH/ ORP Controller

RS485 Modbus MODBUS RTU Single Channel Digital Intelligent PH/ ORP Controller

The single-channel digital intelligent controller of the DUC1 series is a small, compact and lightweight design, which is suitable for the panel installation of the cabinet.

The instrument is connected to and controls other equipment through a relay, and can also use 4~20mA current signal or RS485 digital signal to transmit instrument information.

Product Parameters

Brief introduction:

● Compatible with all DRFN digital pH sensors;
● Separately have a list of controller and sensor settings for quick and detailed parameter setting;
● The working status of the sensor can be queried, including reading the serial number;
● Support a variety of installation methods；
● Time and historical data recording function;
● 3.2-inch large LCD screen;
● User-friendly English language interface;
● Password can be set to prevent misoperation;
● 2 SPST multi-function and settable relays;
● Two way 0/4~20mA active current loop outputs;
● RS485 interface, Modbus RTU communication protocol;
● IP66 waterproof level, sealed enclosure can isolate pollution and corrosive gas;

●The meter has a self-diagnostic function.

It can diagnose the PH/ORP sensor during calibration and maintenance. If the operation is improper or the PH/ORP sensor has poor characteristics, the screen will display the image and the buzzer will prompt briefly. It is recommended that the user re-maintain or replace the sensor.

●The ORP PH controller can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real-time. When the working temperature of the instrument changes, the instrument will compensate for the hardware changes caused by the temperature drift accordingly, making the detection result more accurate, this is a patented technology of daruifuno.
