Safety Timer
The SCB is a universally applicable safety timer, with which the moving parts of a machine or plant can be brought to a standstill quickly and safely. Depending upon the configuration, the safety outputs connect on-delay, off-delay or without delay independent of one another. A simple and accurate time parametrization is possible with a push/rotary button and the display.
Extensive monitoring measures are indicated on the display with detailed error messages. Thus, the SCB not only offers the clear and simple functionality of a safety relay, but also the advantages of safety control devices.
Additionally, the diverse outputs enable a safe shutdown of furnaces in continuous operation according to EN 50156-1 and EN 746-2.
The safe mini timer SCB replaces obsolete pneumatic time relays
Previously used pneumatic time relays usually no longer meet the state of the art. A standard-compliant protection of the system is therefore no longer possible.
The SCB ensures the current state of the art both in the case of a retrofit and when new burner systems are installed, thus ensuring conformity with the applicable standards.
No matter in which industry they are needed: we have the right type of safety time relay:

*We do have non safe timer in our portfolio
*Here you will also find our SR4C: The safe timing relay, which combines instantaneous and delayed contacts in an extremely compact housing
All these variants are available with the following adjustable delay times:
- up to 99 sec
- up to 99 min
- up to 99 h
NEW:
New switching function of the auxiliary outputs ease the retrofit
With the new variants of the mini safety timer SCB (e.g. SCB-02-01) you have the possibility to integrate the auxiliary outputs, analogue to the classic relay technique, inverted to the control concept. Especially in the case of a retrofit, it ease the exchange of an old, not state of the art pneumatic time relay.
New function for an automatic re-triggering leads to less system downtime as well as less intervention through the operating personal
The switch-off delay parameterised on the SCB can be used to filter a brief triggering of a limit monitor so that brief triggering of limit monitors, e.g. temperature, pressure or flow rate, must not lead to a switch-off.
New SCB function for a delayed reset signal for preventing accidental confirmations
With the new "delayed resetting" function, the danger of an accidental reset of the safety system can be prevented.
