Extention modules feed


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.

Advantages

 

Extension modules

  • 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

  • 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

Coupling modules

  • Very safe switching behaviour by positively driven contacts
  • Allow a regulation-compliant implementation of safety-related circuits
  • Prevent retriggering in the case of an error

Technology

 

Extension modules

Compact module with positively-driven safety relays which is triggered by the associated function module (basis module) and monitored via a feedback loop. An extension module can only reach the basis module’s safety category acc. to EN 954-1 as a maximum.

Delay modules

Delay-release time-delay relay with or without auxiliary voltage and adjustable or fixed time setting. High long-term stability thanks to digital timer. Two time circuits working independent of each other to implement a cutoff redundancy. Positively driven release contacts.

Coupling modules

Coupling modules feature safety relays with positively driven contacts according to EN 50205. Positive-action is present if the contacts are mechanically linked to each other so that NC and NO contacts can never be closed at the same time. For this it must be ensured that a contact gap of at least 0.5 mm is present over the whole service life, even in fault condition.

Applications

Extension modules

Multiplication of release circuits of a basis module to cut off any number of control circuits in a safety-related manner.

Delay modules

Quick stopping of a dangerous movement of drives with masses.
A typical example are tools rotating with high speed, which still coast after cutoff for a longer time.

Coupling module

Used, for example, for self-monitoring safety circuits, for the adjustment of control and power levels and for switching safety-related functions.
