6.1.2 Wiring method
Leaky input: connect S/S terminal to +24V terminal. NPN sensors can
be connected in this way. The internal equivalent circuit and external
connection mode of leakage input mode are shown in the figure below.
Source input: Short connect S/S terminal to COM terminal. This way
can be connected to the PNP sensor. The internal equivalent circuit
and external connection mode of source input mode are shown in the

6.2 Switching output characteristics and signal
specifications
The output terminals of MCCD series are divided into several groups,
each group is electrically isolated, and the output contacts of different
groups are connected to different power circuits. The output can be
divided into two types: relay and transistor. Transistor output stages
can only be used in DC 24V load circuits with attention to power
polarity. The inductive load of DC circuit should be considered to
increase the continuation diode; For the inductive load of ac circuit, the
external circuit should consider the RC instantaneous voltage
absorption circuit. As shown in the figure below.
Special function of output port
The transistor output type main module contains three high-speed
output ports Y0,Y1 and Y2. The three channels can independently
output high-speed pulse. Provides high speed I/O instructions and
location instructions to manage high speed output channels. For high
speed output, it is recommended to use double stranded shielding wire
for the corresponding input port, and to ground the shielding layer
(connected with the terminal or connected to the signal ground) to
improve disturbance immunity.
