Safety time control device

SAFETY TIME CONTROL DEVICE Safe and time-delayed shutdown of machines and plants 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 / SIL 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. 2 safety relay outputs for...

Variable function Artikel-Nr. depending on the variant, the SCB has up to four independent safe outputs, which switch on or off timedelayed or non-time-delayed. cat. 4 / Pl e / Silcl 3 according en iSo 13849-1 and en 62061 will always be achieved. 1 zweikanaliger Eingang DC 24 V On-delay safety contacts: depending on the variant, the outputs of the SCB will switch on immediately or time-delayed if the safety circuit i11-i21 and i12-i22 are closed. Off-delay safety contacts: When a safety requirement (e-Stop) prevails, the non- delayed safety contacts will switch off immediately and the time-delayed...

SAFETY TIME CONTROL DEVICE Economical, because … … detailed and clear monitoring. The SCB has an detailed monitoring. Errors such as faulty sensors, short circuits or wrong wiring will be detected and indicated with an error number on the LED-display and via the auxiliary output. This means: Avoiding downtime during troubleshooting Eliminates tedious process of troubleshooting Quick commissioning … complete overview during every operating status! … easy and accurate time setting The SCB can be operated quickly and easily via the push/ rotary button on the front of the housing. By simply turning...

… developed for furnaces and ancillary equipment in continuous operation. the SCB has been specially developed for furnaces and ancillary equipment in continuous operation, for which regular proof-tests cannot be conducted at sufficiently short intervals according to en 50156-1. Thanks to the internal structure of the SCB, the use of diverse contactor groups for connecting the safety-related actuators can be dispensed with. this means • Less downtime for your plant because of proof-test intervals as per en 50156-1 More place in the switch cabinet and reduced wiring effort … ideally suited for...

SAFETY TIME CONTROL DEVICE The right variant for your application. The safety outputs of the SCB can connect in versatile combinations. Time-delayed or non-time-delayed and with on-delay or off-delay. You can decide the configuration of your SCB by selecting one of the standard configurations saved in the device via the menu control. We can also parametrise for you other combinations, like mixed on-delay and off-delay outputs or delayed auxillary outputs. Order Number 474460/1/2 SCB-04 non-inverted switching auxiliary outputs SCB-04-01 inverted switching auxiliary outputs SCB-03 non-inverted...
