2) Open collector output signal

• Connect a relay coil or the input module of a programmable controller as shown

in Figures (a) and (b) below. When using a relay, connect a diode as a surge

absorber in parallel with the coil. Connect that diode as shown in Figure (a) so

that the current flow direction of the diode is opposite the direction that voltage is

applied to the coil.

• Prepare an external power supply for output signals. Do not use the internal

interface power supply (P24-CM1) of the robot driver. The robot driver may fail.

• Electrical specifications for contact output signals are shown in the following
