DOLD Extension modules SAFEMASTER

DOLD Extension / Delay / Interface Modules.

Extension modules:
With extension modules the output contacts of the base modules can be multiplied. It is also possible to strengthen the contacts by dividing it into several control circuits.
Delay modules:
When triggering an emergency stop signal, delayed shutdown may be desired. For example, robots with dangerous movements can be driven into a safe state. The delay modules are available in the versions with release or response delay.
Interface modules:
Interface modules with forcibly guided contacts are used to switch safety-related functions as links between logic and load. The forcibly guided normally closed contacts enable monitoring of the normally open contacts.

Your advantages at a glance with DOLD.

Extension modules:
- Cost-effective contact multiplication universally connectable to the basic modules
- Monitoring of the output contacts via a feedback loop by the respective base module
- Connection of several expansion modules to one basic module
Delay modules:
- Targeted stopping of the drives, thereby reducing the risk of injury
- No loss of productivity, as a targeted restart is made possible
- High long-term stability due to digital time stage
Interface modules
- Particularly safe switching behaviour due to forcibly guided contacts
- Enables standard-compliant implementation of safety-related circuits
- In the event of an error, a new activation is prevented.
