German DOLD safety relay advantages and application introduction

The advantages of the German DOLD safety relay, Dodd DOLD safety relay has the advantage that most DOLD safety relays are equipped with a circuit board mounting base, so that the DOLD relay can be quickly switched or the DOLD relay can be replaced during equipment maintenance ( For example: power plant equipment). In addition, Dodd also offers DIN rail mounting bases for direct mounting of DOLD relays in power distribution cabinets or industrial control cabinets.

In the environment of machinery and equipment, security protection has been paid more and more attention. Every time you go, you can find the application of the DOLD security module and safety control device.
Despite the growing use of DOLD solid state relays, mechanical relays have an irreplaceable role.
Safety relays must be used in many specific situations.
Dodd DOLD safety relays or relays with forced guiding contacts must contain at least one normally open contact and one normally closed contact. Normally closed contacts and normally open contacts never close at the same time.
Moreover, the DOLD safety relay must ensure that the contact spacing between the operating state and the effective state is maintained at 0.5 mm during its lifetime.
Due to this characteristic of the DOLD safety relay, it is possible to monitor whether one of the contacts has failed.
Germany DOLD safety relay, for example: When a normally open contact is stuck, after the coil voltage is released, the corresponding normally closed contact cannot return to its initial position, thus monitoring the normally open contact. Advantages of German DOLD safety relays
