NOTE 1: When an output intelligent terminal is used, be sure to install a surge absorbing
diode in parallel with the relay (RY). Otherwise, the surge voltage created when
the relay (RY) goes ON or OFF may damage the output intelligent terminal cir-
cuit.
NOTE 2: Use a twisted and shielded wire for the signal line, and cut the shielded covering
as shown in the diagram below. Make sure that the length of the signal line is 20
meters or less.
