Efficient Control Cabinet Wiring with Daisy Chains

Posted by Sonja Armbruster on Fri, Oct 14, 2016

Conventional wiring of hardware components inside a control cabinet can be a complex task: Establishing separate connections of single modules eats up time and precious cabinet space. An effective way to minimize the effort is to interconnect multiple modules using a cable with pre-configured wiring links.

If no power supply is available via the DIN rail, this problem can easily be tackled using a daisy chain—a cost-effective connection technology consisting of a single cable with 25 pre-configured links that can be connected to control cabinet modules with screw terminals. This ensures a constant signal transmission between separate modules. As a universal solution, a daisy chain can be used to connect K-System, SC-System, or AS-Interface hardware components, for example.

Used with multi-purpose twist-on connectors, you can easily adapt your module wiring to your specific application.

Here are the three functions possible with a daisy chain:

 1. Connecting

Connecting daisy chainsChoose the required number of connection points and cut the daisy chain to the needed length right at the switch cabinet. This saves time and space, since no more connections than necessary are placed in the cabinet. By using the twist-on connectors, you can isolate non-connected points and stripped wire ends without having to use tools. The removed cable segment can then be easily reused for other connections.



2. Cascading/Daisy-Chaining

Combine two or more daisy chains In case a longer connection is needed, conveniently combine two or more daisy chains via the twist-on connectors. The stripped cable ends of two segments get safely wired inside the connectors.




3. Isolating

Isolating a daisy chain

When a module needs to be removed for maintenance, the serial design of the daisy chain still ensures a reliable signal connection (i.e. power supply) to the remaining modules. If you do not substitute the module with a spare part immediately, you can isolate the open points with the twist-on connectors.
