ProMinent Controller DULCOMETER® diaLog DACa


Intelligent measuring and controlling

The diaLog DACa controller uses intelligent controller functions to close the control circuit between ProMinent® DULCOTEST® sensors and ProMinent® metering pumps. The multi-parameter measurement and control device offers special functions for water treatment, such as the processing of variables and control parameter changeover. The new controller platform from ProMinent® was developed to continually measure and control the parameters required and can be configured for one or two measuring channels depending on application.

Sensors from 14 freely selectable measured variables can be connected per channel. The measurement and control device can communicate with analog or digital* sensors and actuators. The following will be available in the future for communication* with the control level: Profibus® DP, Modbus RTU, OPC and web server via LAN and WLAN.

Features & Benefits

  • Two measuring channels (via mV and mA inputs)
  • Free combination of 14 selectable measured variables
  • Two 2-way PID controllers with 4 metering pump relays
  • Sensor monitoring of pH
  • Control variables monitored by time to avoid incorrect metering
  • Data logger for measured values, control variables, calibration data and events with storage on SD card and depiction on the controller display
  • Storage and transfer of device setup via SD card
  • The pH influence on the chlorine disinfection parameter is compensated
  • Remote setpoint operation available
  • Measured variables and menu language are initialized during commissioning
  • Temperature compensation of measured variables pH, conductivity, chlorine dioxide and fluoride
  • Subsequent extension of software function via activation key or firmware update
  • LAN/Ethernet connectivity
  • Two analog outputs for measured value, correction value or control variable (depending on optional equipment)
  • Five digital inputs for sample water error detection, pause and parameter changeover, chemicals level warning
  • Two relays with limit value function, timer and discontinuous control, 3-point step control (depending on optional equipment)
