The main input is used for sensors for measuring the pH value or the redox voltage. In addition to conventional glass sensors, ISFET sensors or sensors for ammonia concentration can be used. Resistance thermometers Pt100 or Pt1000, NTC/PTC or standard signals 0(4) to 20 mA or 0 to 10 V can be connected to the second analogue input (compensation input). The two binary inputs can be used both as initiators for actions (e.g. HOLD, keypad lock) and when connecting pulse transmitters (e.g. impeller sensors) for flow measurement. The high-contrast graphic display allows the input signals to be displayed with digits or as a bar graph. The display of the parameters in plain text makes operation easy to understand and safe. The controller can be used in a variety of ways by setting it as a two-point, three-point, three-point step controller or as a continuous controller. The controller software also includes parameter set switching and a maths module. A setup programme is available for convenient configuration via a PC. In addition to the standard inputs/outputs already described, the device also has an analogue output. Power is supplied via a switching power supply AC 110..240 V +10/-15 % 48..63 Hz. The electrical connection is made at the rear via screw terminals. EAN: 4053877005100.
