Multi-loop Temp & Process Controllers

When should you use a multi-loop controller?

If you have more than one control loop within a single system then a multi-loop controller can be used. In simplified terms a multi-loop controller can be thought of as having multiple temperature controllers within a single instrument.

 

 

Typical Usage and Benefits

Multi-loop controllers are generally mounted behind the panel as opposed to single loop controllers which are often front panel mounted. The controllers are typically programmed using a proprietary software program on a PC which downloads settings to the multi-loop temperature controller using communications.

 

Using a multi-loop controller rather than multiple single loop controllers can have many benefits. Installation costs can be reduced due to having one common connection point, resulting in less wiring and minimising panel cut outs. Another advantage is controllers can be changed without powering down the system. This process, known as hot-swapping, it significantly reduces machine downtime.
