Retrofit Solutions

Rising costs and increasing legislation in industry means completely replacing older control and instrumentation systems is not always financially viable. JK Controls Ltd is able to offer a range of retrofit solutions, from full system to component level sub-assemblies, to upgrade systems at a lower cost.

SCADA Retrofit
JK Controls replaced an obsolete control system for a power station's generator/grid switchgear within a two day outage. This was achieved by the manufacture of custom interfacing equipment which was plug compatible with the original system I/O connectors, thereby providing considerable cost benefits to the station in terms of downtime and future reliability.

Virtual Chart Recorders
Ageing and obsolete control room chart recorders at a power station in Kent had become unreliable and expensive to maintain. JK Controls designed and built a virtual recorder system based upon PLC input equipment and three SCADA PC's driving twelve TFT liquid crystal monitors. Each display emulated four multipen chart recorders and was mounted in an add-on section of control desk designed by JK Controls, which integrated with the operators original desk. The resulting flexible data display system was provided at low cost compared to replacement costs for the existing recorders.

Legacy Alarm System Renewal
A power station's ageing alarm system had become obsolete due to the original manufacturer no longer being in business. JK Controls provided a cost effective solution by analysing the existing system and then designing and building new solid-state based circuit boards to electrically emulate and be physically plug compatible with the original.
