Brief description

The safety temperature limiter JUMO safetyM STB and the safety temperature monitor JUMO

safetyM STW are used to reliably detect and avert hazards that could cause injuries to people,

that could be harmful to the environment, or that could cause destruction of production plants

and produced goods at an early stage.

Its primary task is to reliably monitor thermal processes and switch the systems to an operational

safe status in the event of malfunctions.

The measured value at the analog input can be recorded by various probes or standard signals.

The exceedance of the limit value is indicated by the installed LEDs K1 and K2 (red) for

each channel, and the safety relevant relay output alarm (terminal 14 and 16) switches the

system to an operational safe status (alarm range).

The high standards of DIN EN 61508 and DIN EN ISO 13849 are met by a device concept that

has a 1oo2D structure (2-channel structure with diagnostic channel) which ensures reliable detection

of errors. This device concept can also be used for applications that correspond to the

new machinery directive 2006/42/EC.

Other measured variables, such as pressure, can also be safely switched off via connection

variant 5.
