HR6S-AB
Safety Module
HR6S-S
Safety Relay Module
• Monitors two-hand control devices (IIIA or IIIC) that are required to comply
with International Standard ISO 13851.
• IIIC can monitor two-hand pushbuttons for synchronization within 0.5
seconds.
• If one of the two buttons is released during operation, the control
sequence is canceled.
• Connects up to two input devices in parallel (except for two-hand control
devices (IIIC)). (Outputs are enabled when all inputs are enabled.)
