DOLD extension, delay and coupling modules

Extension modules

Extension modules can be used to multiply the output contacts of the basis modules. Also contact reinforcement by splitting into multiple control circuits is possible.

Delay modules

The emergency-stop of a dangerous movement can be accelerated by a controlled stop operation according to the stop category 1 by allowing motor brake functions or controlled drive speed reduction to run during the cutout delay.

Coupling modules

Coupling modules with positively driven contacts are used to switch safety-related functions as links between logic circuitry and load. The positively driven NC contacts can be used to monitor the closing contacts.
