Dosing Control Relay And Current Output PH/ORP Controller For Sewage Or Drinking Water
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.
