Solid State Relays available in DIN rail mount

DIN rail mount is one of the main mounting styles for industrial devices

DIN rail has become very common on industrial panels and cabinets, which makes DIN rail mount one of the main mounting styles for industrial devices. DIN rails are the long metal strips that are used for mounting industrial process control devices, such as Solid State Relays. These DIN rails make a fundamental component of industrial equipment cabinet racks and are used for mounting process control products.
As the name implies, DIN rail mount solid state relays are designed to be mounted on a DIN rail. These are mostly used in industrial and commercial applications and have lots of advantages.

Advantages of using DIN Rails In your applications

The following benefits of DIN rails make them suitable for several applications.

DIN rails save space, time, and efforts of mounting each device or component separately.
The limited space requirement is an important benefit as it links internal and external cabling circuits together.
They are cost convenient, and feature universally accepted connection protocols and also offer organized system layout.
The advantage of this type of SSR is that it can be easily installed and removed from the DIN rail.

Now that the importance of DIN rails are discussed, let us introduce you celduc®’s range of DIN Rail Mount Solid State Relays.

Grounding and Safety precautions

DIN-Rail adaptor can be used without a ground wire if the support on which it is mounted is itself connected to the ground.

The mounting and dismounting of SSRs mounted on DIN Rail adaptor should be done when the voltage is off. Some cautions have to be taken by operator to protect himself against injuries from pinch points, cuts, impacts with head, eyes or feet. The operator must be qualified.

Conclusion

In terms of mechanical layout and dimensions of solid state relays, there are several housing that have become industry standard, the most popular one is the hockey puck style housing. Now you can find different package styles allowing the SSRs to be mounted in several different ways, depending on the preferences and the space availability of the user, such as: panel mount, DIN Rail mount and PCB mount. celduc® offers a wide range of products covering all market needs.
