Jumo Conductivity, TDS, resistance measuring transducer/controller 00550843

This conductivity transmitter / controller in the control panel housing is a compact, modular device, which can solve a wide range of tasks thanks to its flexibility with 3 slots for retrofit boards. The main input is used for sensors for measuring the electrolytic conductivity, the specific resistance or the TDS value. For this purpose, two-electrode and four-electrode measuring cells can be connected. The second analogue input (compensation input) is designed for resistance thermometers Pt100, or Pt1000, NTC/PTC or unit signals 0(4) to 20 mA or 0 to 10 V. The two binary inputs can be used as initiators for actions (such as HOLD, keyboard locking) as well as for connection of pulse sensors (such as 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. The device can be programmed as a two-point, three-point, three-point stepping controller or a constant controller. All controller outputs can be configured to P, PI, PD or PID behavior with a convenient setup program (available separately). The controller software also contains a parameter set changeover and a math module. In addition to the already described standard inputs/outputs, the device also has an analog output. The power supply is via a switched-mode power supply AC 110..240V +10/-15% 48..63Hz. The electrical connection is made at the rear via screw terminals.
