HR6S-AK
Safety Relay Module
Connects to pressure-sensitive switches such as mat switches
• Protects both the operator and the machine by immediately stopping
dangerous movements when instructed to stop by the operator or or
when a failure in the safety circuit is detected.
• Connects to pressure-sensitive switches such as mat switches or edge switches.
• NC contact is availalabe for output.
