SELF-MONITORING EMERGENCY-STOP CONTACT BLOCKS

Even redundant, secure emergency-stop chains are ineffective unless the contact block is accurately connected with the emergency-stop switch. The safety contact blocks for emergency-stop heads of SCHLEGEL are the response to this danger that may occur e.g. as a result of a negligent assembly or a mechanical damage. In such a situation, they ensure that the emergency signal is activated and the installation is switched off immediately. It can only be restarted after successful trouble-shouting.

The contact blocks are available as a one or two channel solution with screw or Faston terminals and do have positive opening contacts acc. to IEC60947-5-1. In combination with the emergency-stop head they are foolproof acc. to EN60947-5-5 und EN13850. The high-quality contact elements allow a reliable switching even in case of low currents (5 mA at 24 V or less). They are available as conventional contact blocks as well as for AS-Interface (Safety@Work).
