Abstract

PURPOSE:To make unnecessary the power supply terminals and ground at the master station and relay station side and to enable to transmit the information with 3 items at maximum, by trasmitting one control of the master station to the relay station, and one information of the relay station and other information to the master station, via the loop including parallel lines. CONSTITUTION:The closed relay contact 1 at the master station flows a current to a relay 6 via power supply terminal 9, relay contact 7-3, parallel line 5-1, make contact of relay contact 1, parallel line 5-1, relay contacts 7-2, 7-1. With this loop, one control of the master station is delivered to the relay station. Next, one information of the relay station is delivered to the master station via the loop including the lines 5-2 and 5-1. Further, other information of the relay station closes the relay contacts 7-2, 7-3 at the same time to operate the relay 2-1 for the delivery to the master station. Thus, the power supply terminals and ground are not required at the master and relay stations, and 3 items at maximum can be delivered.
