Two hand safety relays

Two-hand controls on machinery and plants are used to protect operators against injuries by dangerous closing movements. The control unit is located outside the dangerous area to prevent the operator from getting into this area before a dangerous movement is actually stopped. 

• Save cost by leaving out conventional contactor controls

• Type-tested circuits complying with the requirements from the employers’ liability insurance association

• Compact prewired rail-mounted modules
