The PnOZ s9 series General Purpose Relay with 3 safety contacts and 1 auxiliary contact. Contact expander module for increasing the number of available contacts, pulse-ON timer relay for step-by-step control of movement sequences, delay-ON energization timer for unlocking an interlock with delay, shut-down of application with delay-ON de-energization and controlled stop. The delay-ON de-energization, not retriggerable and if the supply voltage at the input circuit is interrupted, the safety contacts will open once the set release time has elapsed, even if the safety function is cancelled during the delay time. The unit cannot be reactivated until the delay time has elapsed. If the supply voltage at the input circuit is interrupted, the safety contacts will open once the set release time has elapsed. If the safety function is cancelled during the delay time (safety gate closed), the unit will remain active.
● Switch-ON time, pulse time or delay-ON de-energization selectable
● The unit can also be used without a base unit as a pulse relay or safe timer
● The unit monitors its own output contacts
● The safety function remains effective in the case of a component failure
● Earth fault in the feedback loop is detected
● The unit has an electronic fuse
