Jumo STB/STW Temperature Limiter, 84 x 45mm 2 (Analogue) Input, 2 Output 2 Change-Over Contacts, Relay, 20 → 30

The Jumo STB/STW series temperature controller has supply voltage ranging from 20VAC/DC to 30VAC/DC. This controller has a width of 45mm and a height of 85mm device. It has two universal analogue inputs, two relay outputs (pre and limit alarm) and a universal analogue output. It has two pt100 programmable measuring input in a 3-wire circuit. This safety temperature limiter (STB) and the safety temperature monitor (STW) detect and avert hazards that are harmful to the environment or cause destruction of production plants and produced goods, or even cause injuries, at an early stage. Its primary task is to reliably monitor thermal processes and switch the systems to operational safe status in the event of malfunctions.
