Sockets for the PCB mouning are available for mostly all safety relays. This allows a fast exchange between the relays at preventive machine care which is often prescribed regularly (eg power station) or in case of service. We provice sockets for DIN- rail mounting.

Customer- specific solutions

We are able to realise customer- specific solutions very fast due to a high production depth here in Furtwangen. We can supply relays with mixed contact types and materials.

Two different types of safety relays are available:

• type A: all contacts are connected mechanically
• type B: relays which have mechanic connected contacts as well as non- mechanic connected contacts. Also change- over contacts belong to this.

Emergency stop monitors

• DIN EN 61810 basic relays
• DIN EN 60255 electrical relays
• DIN EN 50205 relays with positive guided contacts
• DIN IEC 60664 insulation coordination for electrical equipment in low voltage systems

Emergency Stop Modules

Emergency stop modules with semiconductor output are checking periodical the outputs by switching off the output voltage. Controls, frequency converters or servo drives note this and switch off. This is not necessary with emergency stop modules or safety relays from Dold. Therefore, a trouble- free working is guaranteed. In addition, the emergency stop modules have potential free outputs and in most cases contactors won’t be used anymore for higher loads.

Lift Controls

In lift controls Dold safety relays provide that the lift starts only when doors are closed.

Railway Applications

Dold safety relays build a safe and reliable interface between control level and periphery so that the trains do not stop on free road.
