(5) Details of input/output signal wiring
1) Contact input signal
• Contact signals should be input through switches and relays. Figures (a) and (b)
below show wiring diagrams using an external power supply or internal interface
power supply.

(a) When using an external power supply
(b) When using the internal power supply
• Use an external power supply for devices requiring power for controlling a
contact output, such as a programmable controller output module. (Do not use
the internal interface power supply of the robot driver.) Figures (c) and (d) below
show examples for connecting the transistor output module (sink type or source
type) of a programmable controller.
