JUMO 568079 pH-Messumformer/-Regler, inklusiv

This pH transmitter/controller in a panel case is a compact and also a modular device, which can solve the most diverse tasks due to its flexibility (including 3 slots for optional boards). The main input is for sensors to measure the pH value or the redox voltage. Resistance thermometers Pt100 and Pt1000, NTC/PTC or standard signals 0(4) - 20 mA or 0 - 10 V can be connected to the second analog input (compensation input). The two binary inputs can be used either as initiators for actions (e.g. HOLD, keyboard inhibit) or when connecting pulse generators (for example impeller sensors) for flow-rate measurement. The high-contrast graphic display allows for several options including display of input signal with numbers or as bar graph. Parameters are displayed in plain text for easily comprehensible and reliable operation. It can be used as a two-point or three-point controller, three-point modulating controller or continuous controller. The software includes parameter set selection and a math module. A setup program is available for convenient configuration via PC. In addition to the standard inputs/outputs already described, the unit also has an analog output and a relay (changeover contact). The power supply is provided by a switch-mode PSU AC/DC 20..30 V 48..63 Hz. The electrical connection is on the back via screw terminals.
