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.

• Cost-saving contact multiplication, universal connectivity to all basis modules

• Monitor output contacts via a feedback loop through the relevant basis module
 
• Connect multiple extension modules to a single basis module by cascading

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.

• Controlled stop operation of drives minimizes the risk of injuries
 
• No adverse effects on productivity as immediate restarting is possible
 
• High long-term stability by digital timer
