As shown, the circuit consists of TX315B1 type transmitter / receiver components to receive decoder circuit of four high output control signal. Driving through the transistor connected to four self-locking relay to AC power. Receive Groups pieces of the output of the A ~ D access VT1 ~ VT4 four relay driver tubes, each drive tube drives a self-locking relay output Io K. VT5 is formed by the emitter of VT1 ~ VT4 channel controller. Only when Io output signal decoding effective after the VT5 conduction, VT1 ~ VT4 are possible to conduct.
