This pH transmitter/controller in the control panel housing is a compact yet modular device which, thanks to its flexibility (including 3 slots for optional boards) can solve a wide range of tasks. The main input serves for sensors to measure the pH-value or the redox voltage. In addition to conventional glass sensors, ISFET sensors or ammonia concentration sensors can be used. At the second analogue input (compensation input) resistance thermometers Pt100 or Pt1000, NTC/PTC or unit signals 0(4) to 20 mA, or 0 to 10 V can be connected. The two binary inputs can be used as initiators for actions (e.g. B. HOLD, keyboard locking) as well as with the connection of pulse sensors (e. B. Impeller sensors) for flow measurement. The high-contrast graphic display allows the display of the input signals with digits or as a bar graph. The display of the parameters in plain text makes the operation easy to understand and safe. It can be used in many different ways by using it as a two-point, three-point, three-point stepping controller or constant controller. The controller software also contains a parameter set changeover and a math module. A setup program is available for convenient configuration from a PC. In addition to the already described standard inputs / outputs, the device additionally has an analog output and a relay (changer). Power is supplied by a switched-mode power supply AC 110..240 V +10/-15% 48..63 Hz. The electrical connection is made at the rear via screw terminals.This text is machine translated.
