Interface modules with forcibly guided contacts


DOLD interface modules with forced contact, available from ELTRON, are specialised components designed for use in safety systems where reliable status signalling and signal separation are crucial. These devices meet the requirements of the EN 50205 standard, guaranteeing safe switching even in high-risk environments.

Forced contact guidance means that a normally closed (NC) contact and a normally open (NO) contact cannot be closed at the same time, which allows contact blocking to be detected and prevents potential errors in the safety system. This makes DOLD interface modules the ideal solution for monitoring safety relay contacts, fault signalling and checking the correct operation of output circuits.

These modules also enable galvanic isolation of signals, voltage level conversion and signal conversion between different logic systems. Thanks to their compact housing and standard DIN rail mounting, they are easy to install and integrate into existing systems.

ELTRON, as an authorised DOLD partner in Poland, offers full technical support, availability of modules from stock and assistance in selecting the right solution for a given industrial automation or safety system application.
