SCB safe time control

The SCB is a universally applicable, safe time control with which the moving parts of a machine or system can be shut down quickly and safely in the event of danger. Depending on the configuration, the safe outputs switch independently of one another with an on-delay, off-delay or instantaneous. A simple and precise time parameterization is made possible by a push button, rotary switch and the integrated display.

Comprehensive diagnostic measures are indicated by detailed error messages on the display. Thus, in addition to the clear and simple functionality of a safety relay, the SCB offers the advantages of safe controls.

The diverse outputs also enable safe shutdown of combustion systems in continuous operation according to EN 50156-1 and EN 746-2.

The safe mini time control SCB replaces outdated pneumatic time relays

The pneumatic timing relays used up to now mostly no longer meet the state of the art. A standard-compliant safeguarding of the system is not possible.

The SCB ensures the current state of the art, both in the event of a retro fit and when installing new burner systems, and thus conformity with the applicable standards.

Regardless of which industry you come from: We have the right safe timing relays.
