Description:

This instrument measures and controls (depending on the configuration) the pH value or redox potential of aqueous solutions.
The transmitter features two analogue and two logic inputs. The first analogue input is suitable for connecting a pH combination electrode, or a glass and reference electrode (also antimony), or a redox combination electrode, or a metal and reference electrode. The second analogue input can be used to connect RTD Pt100 or Pt1000 resistance thermometers.
The instrument features two 4-digit 7-segment displays for indicating the pH or redox potential process value (red) and the temperature (green).
During programming, the displays provide comments on the inputs.
A great variety of control tasks can be handled by the various output options (relay contacts and/or analogue outputs). The two relay "make" contacts that are provided on the instrument as standard can be configured as a limit controller and/or pulse width or pulse frequency controllers, or as a modulating controller. To obtain analogue (continuous) controller outputs, the optional analogue outputs must be configured accordingly.
All controller outputs can be configured for a P, PI, PD or PID control action.
In the entry-level version, the instrument provides two relay "make" contacts and one logic output (0/5V). Two additional outputs can, according to choice, be fitted with relay changeover contacts and/or analogue outputs (process value output or analogue controller output) or as a serial interface (Profibus-DP or Modbus/Jbus protocol).

Features:

  • Panel-mounting instrument, just 96 x 48 x 110 mm
  • Display pH or mV/ORP and temperature
  • Switchable from pH to mV/ORP (redox potential)
  • 2 relays as standard, freely programmable as limit controller or P, PI, PID, PD controller with pulse width/pulse frequency output or modulating controller
  • 2 electrically isolated analogue outputs 0(4) - 20 mA / 0(2) - 10 V freely configurable as process value output for pH, redox or temperature, or for continuous controllers (option)
  • 2 logic inputs
  • Temperature of medium can be monitored
  • Simple, step-by-step calibration procedure
  • OPTION: Profibus-DP or serial interface RS485/422 with Modbus/Jbus protocol
  • Panel-mounting housing to DIN 43 700, front protection IP65
  • Wall-mounting housing: IP67 protection
  • JUMO Datasheet; 20.2530
