PURPOSE:To miniaturize a controlled unit, and to simplify a circuit by holding a control timing signal by a common controller. CONSTITUTION:Channel controller SPC receiving 1st synchronizing signal ST from common controller CC and a signal through an information signal, gate G2 sets contents of information lines 8 to 15 to register R0 as device assignment information of the relay or switch. After the reception of 2nd signal ST from CC and a signal through information line O, gata G0 allows gate GRL to open and driver circuit DV is controlled by timing signal strings of lines 8 to 15. Here, the timing signal string is held in the buffer register inside CC. |
