Abstract
An achieving method of a high compatibility relay interface board for detecting computer interlocking logical functions is characterized by adopting a relay board to control operation and release of 16 relays. Driving voltage of a coil of each relay is 24 volts direct current (VDC), and each relay is in parallel connection with a light-emitting diode and a rectifier. When no voltage is input into the relay board, dynamic contact points of the relays are closed with normal-closed static contact points. When 24-VDC voltage is input into the relay, the light-emitting diodes corresponding to the relays are lighted, the relays operate continuously, and the dynamic contact points of the relays are opened with the normal-close static contact points and closed with normal-open static connection points. Each relay has two groups of normal-open contact points and two groups of normal-closed contact points, the coils of the relays and the contact points are all controlled by a toggle switch, and different control and collecting circuits are simulated by operating the toggle switch. The achieving method achieves a plurality of interlocking simulation through a mode of allocating the toggle switch and different external connection wires matched with the toggle switch, and has the advantages of low cost, few working hours and less needed cost.
