NewElec relays facilitate the automation of older plants
October 2014Operator Interfaces, Switches & Relays
The older a manufacturing plant is the more difficult and costly it is to run efficiently, therefore automating the plant can only prove beneficial. NewElec’s MA or NewCode motor protection relays make it easy to adjust the operations of an older plant for maximum productivity. The advantage in automating an older plant can be found if the motor protection and control relays used can accommodate digital inputs that operate on the same auxiliary supply voltage as the existing hard-wired plant. When this is possible, automating such a plant would only require a PLC of sufficient capacity to meet the plant’s demands.
By automating an existing plant, considerable savings can be made, and by converting it to modern monitoring methods, personnel would be familiar with the existing equipment. Training of operations personnel will be kept to an absolute minimum as very little will have been altered in the system.
Introducing the solution is very simple. The NewElec MA or NewCode range of motor protection and control relays may be used to achieve this goal as both facilitate utilising the existing control voltage of the plant/MCC (24 to 220 volts AC or DC). All that is required to achieve the desired automation is a minor manipulation of the existing control circuit layout and the acquisition of a suitable PLC. To achieve this end NewElec will also render the necessary expertise. The existing plant can be transformed into a modernised, automated and well controlled operation.
