HR6S-AB
Safety Relay Module
PLc achieved with Category 1 configuration
• With a variety of common input devices, the HR6S-AB can monitor two-
hand control devices (IIIA) that are required to comply with ISO 13851.
• Suitable for use as a self-holding circuit for selecting a wide variety of
start functions for low-risk machines.
• Output cannot be expanded using expansion modules.
