STB 55 LIMITER
STB 55 - temperature limiter, certified limiter SIL2, DIN EN 14597.
Certified stop SIL 2, DIN EN 14597 (interchangeable for DIN 3440). Intended for safety systems in thermal processes requiring certification, e.g. boilers, reactors.
It can be used as: temperature safety limiter (STB) - after exceeding min / max, a manual reset must be carried out, temperature limiter (ASTB) - operation as above, monitoring (STW) - outputs on / off, depending on the process value.
