The new safe time control device SCB is a safety relay in a very compact design measuring only 22.5 mm, which offers a number of functions for the safe and time-delayed shutdown of machines and plants. It fulfils the highest safety requirements cat. 4 / PL e / SILCL 3 according to EN ISO 13849-1 and EN 62061 and is thus, ideal suited for machine tools and automatic machines.

Additionally, the SCB also applies furnaces and ancillary equipment in continuous operation according to EN 50156-1. It is available with different adjustable delays up to 0-99h and provides an accuracy of ≥ 0.1 sec.

The SCB series offers different types with 2 safe semiconductor and/or 2 safe relay contacts:

• SCB-04: The Safety Timer with 2 safe semiconductor and 2 safe relay outputs
• SCB-03: The Safety Timer with 3 safe semiconductor outputs
• SCB-02: The Safety Timer with 2 safe relay outputs

All these variants are available with the following adjustable delay times:

• up to 99 sec
• up to 99 min
• up to 99 h
