RELAY TYPE INTERLOCKING SYSTEM WITH REMOTE CONTROL

摘要

An electronic type relay interlocking system with remote control is provided to be convenient for maintenance and repair by using a computer instead of a conventional control board in a mosaic manner. An electronic type relay interlocking system with remote control comprises a relay interlocking device(510), a control device, and a signal line(550). The relay interlocking device controls a field instrument(520) by serially operating a relay. The control device monitors and controls operation of the relay interlocking device. The signal line electrically connects the relay interlocking device and the control device. The control device has a machinery room control device(100) and a display control unit(200). The machinery room control device outputs a control order to the relay interlocking device by using a microprocessor by being directly connected to the relay interlocking device in a station. The display control unit electronically controls the machinery room control device.
