Jumo pH transmitter

This pH measuring transmitter/controller in a panel housing is a compact and modular device that can solve a wide range of tasks due to its flexibility (including 3 slots for optional boards). The main input is designed for sensors measuring pH values or redox voltage. In addition to conventional glass sensors, ISFET sensors or sensors for ammonia concentration can be used. The second analog input (compensation input) can accommodate resistance thermometers Pt100 or Pt1000, NTC/PTC, or standard signals of 0(4) to 20 mA, or 0 to 10 V. The two binary inputs can be used both as initiators for actions (e.g., HOLD, keyboard lock) and for connecting pulse generators (e.g., paddle wheel sensors) for flow measurement. The high-contrast graphic display allows for the representation of input signals in digits or as a bar graph. The display of parameters in plain text makes operation easy to understand and secure. The device can be configured as a two-point, three-point, three-point step controller, or as a continuous controller, offering versatile applications. The controller's software also includes parameter set switching and a mathematics module. A setup program is available for convenient configuration via a PC. In addition to the standard inputs/outputs already described, the device also features an analog output and a relay (changeover). The power supply is provided via a switch-mode power supply AC 110..240 V +10/-15 % 48..63 Hz. Electrical connections are made at the rear via screw terminals.
