PLC digital input wiring:
Port short connection: The S/S of the PLC input terminal is connected
to 24V, and the X terminal is connected to the power supply 0V, that is,
the input has a signal;
Two-wire system (magnetic control switch): PLC switch input is connected
to a two-wire magnetic control switch, the positive pole of the magnetic
control switch is connected to the X terminal, and the negative pole is
connected to 0V;
Three-wire system (photoelectric sensor or encoder): PLC switch is
connected to a three-wire photoelectric sensor or encoder, the power
supply of the sensor or encoder is connected to the positive power
supply, and the signal line is connected to the X terminal; the encoder
and photoelectric sensor are required to be of NPN type
(PNP needs special customization).
PLC digital output wiring:
Transistor: The output is NPN, COM is connected to the negative pole, and
Y is connected to the positive pole of the power supply after the load;

D8073 is the smoothing filter coefficient of all analog inputs, the setting range is 0~999.
The number of filter cycles=(R23600~R23607)*PLC scan time, the default is 100, the data cannot
be less than or equal to 0. If R23600=1, a PLC scan cycle is sampled once and the value in the
first analog input is changed once. The larger the value of R23600~R23607 is set, the more
stable the result value is.
Sampling of analog inputs
Note: The 5V driver must have a 2KΩ resistor in the DC24V string.

FROM instruction can read directly: FROM K0 K0 D400 K8, read out 8 analog inputs.
Register read directly: D[8030]~D[8037] is the input value of analog [AD0~AD7];
The constant scan time is changed to D8059, which is started by M8039 (this function is
available in version 26232 and above). When the analog input has a thermocouple type, only
7 channels can be used, and AD4 (D8034) is the ambient temperature of the thermocouple.
8 channels can be used when there is no thermocouple type.

The PLC input (X) is an externally powered DC24V sink type (passive NPN) with the input signal
isolated from the power supply. When using, connect S/S to 24V positive external power supply.
The equivalent circuit of the transistor output type PLC output part is shown in Diagram11. From the Diagram, the output
terminals are in several groups, and each group is electrically isolated. The output contacts of different groups can be
connected to different power circuits; the transistor output can only be used for DC 24V load circuits. The output wiring
mode is NPN, COM common cathode.
For the inductive load connected to the AC loop, the external circuit should consider the RC instantaneous voltage
absorption circuit; for the inductive load of the DC loop, consider adding a freewheeling diode, as shown in Diagram 12.
The wiring of stepper or servo motor is shown in Diagram 13. The default Y0-Y7 of 3G series PLC are
pulse points, and the direction can be customized.
PLC analog wiring
PLC anti-interference processing
1. Strong and weak power should be separately routed, not common; when there is strong electrical interference, add a
magnetic ring at the power supply end; and perform proper and effective grounding according to the type of casing.
2. When the analog quantity is disturbed, 104 ceramic capacitors can be added for filtering and correct and effective grounding.

Analog input register (AD means analog input, precision 12 bit); supports FROM instruction
or direct register reading
Note: For analog input range and register corresponding value, please refer to
"Coolmay CX3G&FX3GC Series PLC Programming Manual"
Analog output register (DA means analog output, precision 12 bits); support TO instruction or direct register
assignment operation
Register direct assignment operation: D[8050]~D[8055] correspond to the analog output value of [DA0~DA5],
which occupies 2DA when negative voltage output is selected, and the set value range is as follows:
FX3GC PLC's soft components are permanently maintained after power-off, that is, all soft components in the holding
area will not be lost after the module is powered off.
The real-time clock uses a rechargeable battery to ensure that the clock is the current time. All power-down retention
functions must ensure that the voltage of the DC24V power supply is
above 23V after loading, and the PLC power-on time is longer than 2 minutes, otherwise the power-down function
will be abnormal.

Two-wire system: the positive pole of the power supply is connected to the positive pole of the transmitter, the
negative pole of the transmitter is connected to the AD terminal, and the negative pole of the
power supply is connected to the GND terminal; generally the wiring mode of the 0~20mA/
4~20mA transmitter;
Three-wire system: the positive pole of the power supply is connected to the positive pole of the transmitter,
the negative pole of the power supply and the negative pole of the signal output are the
same terminal, and the signal output of the transmitter is connected to the AD terminal;
The temperature analog is connected to the AD terminal and the GND terminal respectively. If it is a
three-wire PT100, it needs to be connected in two lines. The GND common terminal of analog input and
output can be shared.
Four-wire system: the positive pole and negative pole of the power supply are respectively connected to the
positive and negative poles of the power supply of the transmitter, and the positive and
negative poles of the signal output of the transmitter are respectively connected to the
AD terminal and the GND terminal;

1. Please confirm the power supply voltage range of this product (Regular product
power supply is only 24V DC! The recommended output power of the power supply is
18W and above) and correct wiring before turning on the power to avoid damage.
2. When installing this product, please tighten the screws or clamp the guide rails
to avoid falling off.
3. Avoid wiring and plugging or unplugging the cable plug in a live state, otherwise
it is easy to cause electric shock or circuit damage. When the product emits peculiar
smell or abnormal sound, please turn off the power switch immediately. During screw
hole processing and wiring, do not drop metal chips and wire ends into the ventilation
holes of the controller, which may cause product failure and misoperation.
4. Please do not tie the power cord and the communication cable together or get too
close, keep a distance of more than 10cm. Strong current and weak current should be
separated and properly and effectively grounded. In severe interference situations,
shielded cables should be used for communication and high-frequency signal input and
output cables to improve anti-interference performance. The grounding terminal FG on
this machine must be grounded correctly to improve the anti-interference ability.
5. The digital input is external power supply DC24V drain type (passive NPN), and the
input signal is isolated from the power supply. When in use, connect S/S to the 24V
positive of the external power supply.
7. Please do not disassemble the product or modify the wiring at will. Otherwise it
may cause failure, malfunction, loss, or fire.
8. When installing and disassembling the product, please turn off all power supplies,
otherwise it will cause the equipment to malfunction or fault.
6. The COM of the digital output (transistor) is a common cathode.
