Jumo 202551 Surface Mount Controller, 96 x 48mm 4 Input Relay Controller

The Jumo pH transmitter 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) 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 either as initiators for actions (e.g. HOLD, keyboard inhibit) or when connecting pulse generators for flow rate measurement. 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. In addition to the standard inputs/outputs already described, the unit also has an analogue output and a relay (changeover contact).
