from the power supply. Connect COM to positive 24V of external power supply while using.
Figure 7 shows the equivalent circuit diagram of the relay output module. The output terminals are several
groups and each group is electrically isolated. Different groups of output contacts are connected to different
power circuits.

* Analog input is AD0-AD15 and output is DA0-DA7. Negative
terminals are connected to GND of input and output respectively.
One negative voltage output will occupy 2 DA and max 4 negative
voltage outputs can be optional. (Only connect DAx and GND.
Please be subject to the test report in your package. )
The equivalent circuit of the transistor PLC output is shown in Figure 8. Seen from the figure, the output
terminals are several groups, and each group is electrically isolated, and different groups of output contacts can
be connected to different power circuits. The transistor output can only be used for DC 24V load circuits. Output
wiring is NPN, COM cathode.
For the inductive load connected to the AC circuit, the RC transient voltage absorption circuit should be
considered on the external circuit. For the inductive load of the DC loop, adding a freewheeling diode should be
considered, as shown in Figure 9.
Stepping or servo motor wiring is shown in Figure 10. 5V drive must connect a 2KΩ resistor on DC24V.
4-channel pulse are Y0, Y1, Y6, Y7, and customized 5-channel are Y0, Y1, Y6, Y7 and Y10.
PLC anti-jamming processing
1. Strong electricity and weak electricity should be separated wiring and not common ground. When there is
strong electric interference, add magnetic ring on the power supply. And do correct and effective grounding
according to the type of the chassis.
2. When the analog is disturbed, 104 ceramic capacitors can be added for filtering, and a correct and effective
grounding can be performed.
More details please refer to Methods of Coolmay PLC anti jamming processing

PLC analog wiring
Two-wire system: The positive pole of the power supply is connected to that of the transmitter, and the negative
pole of the transmitter is connected to the AD side, and the negative pole of the power supply
is connected to the GND. Generally it is the wiring method of the 4-20MA/0-20MA transmitter.
Three-wire system: The positive pole of the power supply is connected to that of the transmitter. The negative of
the power supply and that of the signal output are the same terminal. The transmitter signal
output is connected to the AD terminal.
Four-wire system: The positive and negative terminals of the power supply are connected to those of the
transmitter respectively, and the positive and negative of the transmitter signal outputs are
connected to the AD and the GND terminal respectively.
The two wires of the temperature analog are connected to the AD 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 the analog input and
output can be shared.

TIPS Please read carefully the related manuals before using our
products, and use this product under the environmental
conditions specified in this manual.
1. Power on after confirmed the voltage (24VDC, >18W) and right wiring to avoid damage.
2. Tighten the screws or the rail while mounting the product to avoid falling off.
3. Avoid wiring or plug the cable with electricity, or it is easy to cause electric shock or circuit
damage. When the product emits odor or abnormal sound, please immediately switch off the
power. While processing screw holes or wiring, do not drop the metal chips and wire head into
the ventilation hole of the controller, which may cause product failure and disoperation.
4. Do not tie power cables and communication cables together or close and keep them at a
distance of 10cm or more. Strong and weak currents need to be separated and correctly
grounded. In severe interference situations, input and output cables of the communication and
high-frequency signals should use shielded cables to improve anti-jamming performance. The
grounding terminal FG on this unit must be properly grounded to improve the anti-interference
ability.
5. DI is an externally powered DC24V sinker (passive NPN), and the input signal is isolated from
the power supply. Connect S/S to 24V of external power supply while using.
6. DO (transistor) COM is common cathode.
7. Please do not disassemble the product or change the wiring. Or it will possible to cause
breakdown, malfunction, loss, or fire.
8. While installing or disassembling the product, ensure to turn off all power. Or it may cause
malfunction and breakdown.

PLC: compatible with Mitsubishi PLC programming software GX WORKS 2.
HMI: Coolmay HMI programming software

The soft elements power retentive of HMI PLC all-in-one is permanently retentive, i.e., all the soft
elements in the holding area are not lost if the module is powered off. The real-time clock uses a
rechargeable battery to ensure that the clock is the current time. All power retentive functions must ensure
that the voltage is 23V or higher when DC24V power supply with loads, and the PLC power-on time is
longer than 2 minutes. Otherwise, the power retentive functions will be abnormal.

Registers read directly: D[8030]-D[8045] are the input values of [AD0~AD15].The constant scan-time will change to D8059
and started by M8039 (version 26232 and higher). It supports max 15 analog inputs when there exist thermocouple type, and
AD4[D8034] is the ambient temperature of thermocouples. It supports max 16 analog inputs without thermocouples.
Analog input register (AD,accuracy 12 bits). Support FROM demand or register read directly.
The temperature type is one digit after the decimal point, i.e. 182 = 18.2 degrees.
AD sampling
Filter cycles = (R23600~R23615)* scan time of the PLC. The default value is 100 and the data cannot be
less than or equal to zero. If R23600=1, one PLC scan cycle samples once, and the value in the first analog
input is changed once. The larger the value of R23600~R23615 is set, the more stable the result is.
D8073 is the smoothing filter coefficient of all analog inputs. The setting range is 0~999.
