Extension modules SAFEMASTER
With the expansion modules from DOLD, you can simply multiply the output contacts of the basic modules in order to be able to deactivate any number of control circuits safely. These are compact switching devices with forcibly guided safety relays that are controlled by the respective function module (basic module) and monitored via a return circuit. A cost-effective contact multiplication is made possible through the division into multiple control circuits.

DOLD Interface modules forcibly guided SAFEMASTER
Interface modules forcibly guided SAFEMASTER
Coupling modules from DOLD are constructed with forcibly guided contacts as per EN 50205. The forcibly guided opener allows the monitoring of the closing contacts. As a link between logic and load, they are used for the switching of safety-oriented functions. DOLD coupling modules are also used in the set up of self-monitoring safety switches. They are also the devices of choice for the adjustment of the control and power level as well as for the switching of safety-oriented functions.

DOLD Delay modules SAFEMASTER
Delay modules SAFEMASTER
Delay modules from DOLD allow the specific shut-down of the drives which reduces the risk of injury. A typical use is high-speed tools that continue to move after shut-down. Productivity is not affected as the machine can be immediately started again. The emergency stop of the dangerous movement can be accelerated through a specific shut-down in accordance with stop category 1 by allowing motor braking functions to be applied during the switch-off delay and/or the speed of the drive can be regulated.

Technical Information and Features

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.
