Equivalent circuit

Digital input wiring
The PLC input (X) is a biphasic optocoupler, and users can choose between NPN or PNP connections when using it. However, please note that since the common terminals of the input points are all connected, each module or host can only have one wiring method and cannot be mixed.
The 24V and OV terminals already have internal power supply, which can be directly used as input for pointX.

Two wire system (magnetic switch): PLC switch input is connected to a two-wire magnetic switch, with the positive pole of the magnetic switch connected to the X terminal and the negative pole connected to OV;
Three wire system (photoelectric sensor or encoder): The PLC switch is connected to the photoelectric sensor or encoder of the three wire system. The power supply of the sensor or encoder is connected to the positive pole of the power supply, and the signal line is connected to the X terminal; Encoders and photoelectric sensors require NPN type.

Two wire system (magnetic control switch): PLC switch input is connected to a two-wire magnetic control switch, with the negative pole of the magnetic control switch connected to the X terminal and the positive pole connected to 24V;
Three wire system (photoelectric sensor or encoder): The PLC switch is connected to the photoelectric sensor or encoder of the three wire system. The power supply of the sensor or encoder is connected to the positive pole of the power supply, and the signal line is connected to the X terminal; The encoder and photoelectric sensor require PNP type.

Digital output wiring
Figure 7 shows the equivalent circuit diagram of the relay output module, with several groups of output terminals that are electrically isolated from each other. The output contacts of different groups are connected to different power circuits.
The equivalent circuit of the output part of the PLC with transistor output type shown in Figure 8. As can also be seen from the figure, the output terminals are divided into several groups, and each group is electrically isolated. The output 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 method is NPN, COM common cathode.

For inductive loads connected to AC circuits, the external circuit should consider the RC instantaneous voltage absorption circuit; Corresponding to the load of the DC circuit, it should be considered to add a freewheeling diode, as shown in Figure 9.

The wiring of the stepper or servo motor is shown in Figure 10. The LOlS series transistor output PLC defaults to YO-Y3 as pulse points, and the direction can be customized.As shown in Figure 10. Note: A2K O resistor must be connected in series with DC24V for SV drive.

Analog wiring
The L01-16M/34M series can be selected with a maximum analog input of ADO-AD3, analog outputs ofDAO and DAl, and negative terminals connected to the GND of the analog input/output terminals.
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 method for 4-20mA/0-20mA transmitters is used;
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;
Four wire system: The positive and negative poles of the power supply are connected to the positive and negative poles of the transmitter, respectively. The positive and negative poles of the transmitter signal output are connected to the AD terminal and GND terminal, respectively; The temperature analog quantity is connected to the AD terminal and GND terminal separately. If it is a three wire PTlOO, it needs to be combined into two wires and then connected.

PLC anti-interference processing

  1. Strong and weak electricity should be wired separately and cannot be grounded together; When there is strong electrical interference, add a magnetic ring at the power supply end; And carry out correct and effective grounding treatment according to the type of casing.
  2. When the analog signal is disturbed, a 104 ceramic capacitor can be added for filtering and correctly and effectively grounded.

Note: For more detailed information, please refer to the “PLC anti-interference processing method” on the official website of Cool may

Programming reference

  • Analog input register (AD stands for analog input) with an accuracy of 12 bits supports direct reading of registers:

D [lllO]~D [1113] are the input values corresponding to the analog quantities [ADO~AD3], channel switch D1114;
Note: When the analog input has a thermocouple type, a maximum of 3 channels can be used, where AD3 [D1113] is the ambient temperature of the thermocouple.
When there is no thermocouple type, 4 channels can be used.

The power-off retention of LOlS PLC’s software components is permanent, meaning that all software components in the retention area are not lost after the module is powered off. The real-time clock uses non rechargeable batteries for easy replacement by users. All power-of f retention functions must ensure that the voltage of the DC24V power supply with load is above 23V, and the PC is powered on for more than 2 minutes, otherwise abnormal power-off function may occur.

TIPS

LOlS series programmable controller (PLC) user manual
Before using this product, please carefully read the relevant manual and use it under the environmental conditions specified in the instruction manual.

  1. Please confirm the power supply voltage range of this product (conventional product power supply AC220V!) and correct wiring before powering on to avoid damage.
  2. When installing this product, please make sure to tighten the screws or clamp the guide rail to avoid detachment.
  3. Avoid wiring or unplugging cable plugs while in a live state, as it may cause electric shock or circuit damage; When the product emits an odor or abnormal sound, please immediately turn off the power switch; When processing screw holes and wiring, do not let metal shavings and wire heads fall into the ventilation holes of the controller, as this may cause product malfunctions and misoperation.
  4. Do not tie the power cord and communication cable together or place them too close together. Keep a distance of more than 10cm; Strong and weak currents need to be separated and properly and effectively grounded; In situations with severe interference, shielded cables should be used for communication and high-frequency signal input and output to improve anti-interference performance. The grounding terminal FG on this machine must be properly grounded to improve anti-interfer­ence ability.
  5. The switch input is an external power supply DC24V leakage type (passive NPN), and the input signal is isolated from the power supply. When using it, the S/S needs to be connected to the 24V positive of the external power supply.
  6. The Cx of the output common terminal of a switching transistor is a common cathode.
  7. Please do not disassemble the product or modify the wiring at will. Otherwise, it may cause malfunctions, malfunctions, losses, and fires.
  8. When installing and disassembling products, please make sure to cut off all power sources, otherwise it will cause equipment malfunction and malfunction.
