The solenoid interlock AZM400 has a high locking force of 10,000 newtons. Through its dual-channel release signal, it achieves PL e and SIL 3 safety performance levels for both its locking and interlock functions. Users can connect several AZM400s to a PROFINET/PROFIsafe node in a safety circuit when combined with Schmersal’s new Safety Fieldbox, which enables to avoid other equipment for each individual interlock with a PROFINET interface.
When the Safety Fieldbox is used, safety interlocks of different types (electronic and electro-mechanical) require just one device connection
Thanks to its universal device interface with an 8-pole M12 connector, the Safety Fieldbox can be used to connect an extensive variety of safety switchgears such as safety interlocks, switches, sensors, light curtains and operation panels. The Safety Fieldbox has also an additional digital input to ensure higher machine availability, as the diagnostic signals from all connected safety switchgears are transmitted to the controller via this digital input. This delivers status information for interlocks and error messages for evaluation; thus, preventive maintenance can help eliminate machine downtimes.
A simplified solution that does not need any additional installations for controlling the interlock or reading diagnostic information
The AZM400 has a new accessory: a lockout tag that protects users from being locked inside larger, walk-in systems and machines by mistake while they are performing servicing and repair work. The service personnel can attach a padlock to the lockout tag when entering the hazard zone, then the safety system door can no longer be closed, and the machine is prevented from starting up unintentionally. Up to six padlocks can be attached to the lockout tag, consequently, up to six people can enter the hazard zone at the same time.
