Semiconductor solid control relay

It is a hybrid product that combines power semiconductor device and sealed-type relay by converting the LCP (Local Control Panel) function of 25.8kV GIS (Gas Insulated Switchgear) into a high-speed PLC (Programmable Logic Controller). The kit has improved upon the disadvantages of auxiliary relay used in existing gas insulated switchgears.

A hybrid type device that combines a power semiconductor device and a sealed-type relay by converting the controller of the 154/345kV ILC (Interlock) panel into a high-speed PLC (Programmable Logic Controller). A logic product of keep-type relay.

As a multifunctional auxiliary relay, it is a non-heating structure that uses instantaneous excitation by the usual method of existing auxiliary relay. It maximizes user convenience such as selection of monitoring power (AC, DC) and contact composition (‘4a’, ‘2a2b’, and ‘4b’) and time delay using the front select switch.
