JUMO safetyM STB/STW Ex
Safety Temperature Limiter and
Safety Temperature Monitor According
to DIN EN 14597
Brief description
The compact and freely configurable JUMO safetyM STB/STW Ex can now also enable early
and reliable detection of risks in Ex-areas which could potentially result in personal injuries, en-
vironmental damage, or destruction of the production plant and production materials.
The devices are marked as follows:
The primary task of safety temperature limiters is to reliably monitor thermal processes and to
switch plants to a safe operational state in the event of malfunctions. Along with the existing ap-
provals according to DIN 14597, SIL3, PL e (Performance Level), GL, the device also has ap-
proval according to ATEX and can therefore also be used in Ex-areas. The inputs are intrinsically
safe [Ex ia] so that relevant probes can be connected directly.
Barriers are no longer required. The device is also certified according to DIN EN 50495 and DIN
EN 13463-6 as a monitoring device for potential ignition sources (iPL 2) as specified in the ATEX
directive and can be used to monitor potentially explosive atmospheres containing gas or dust.
The device concept also meets the stringent requirements of DIN EN 61508 and DIN EN 13849.
The 1oo2D structure ensures reliable detection of faults, meaning that the device concept can
also be used for applications subject to the new Machinery Directive 2006/42/EC.
Along with the keypad, the clear and well structured back-lit display with plain text provides
quick and straight-forward configuration directly on the device. The clear menu structure en-
sures easy operation, which in turn shortens commissioning time. All safety-relevant process
values are displayed and the most important functions are represented by simple icons.
