Before the extension module is connected to the main module, the sum of the current consumed by each power supply of the extension module must be calculated to ensure that the current of each power supply is less than the output current that can be provided by the corresponding power supply of the main module to avoid overloading the power supply of the main module. 3 Input characteristics 3.1 Internal equivalent input circuit The I/O expansion module requires external access to the user's switch state detection power supply (24 Vdc), the internal equivalent resistance of the input circuit is about 4.3 k, the detection of the signal uses a bidirectional optocoupler, the user can use the source type or the drain type, only the access to the dry contact switch signal is required. The internal equivalent power supply and input signal wiring of the I/O expansion module is similar to the input circuit of the main module, as shown in Figure 3-1. 5 User signal wiring +24V Main ModulCe OM Expansion Module Internal Equivalent Circuit Logic circuit operating power 24V/5V/GND S/S Various signal input devices X0 X1 X2 Xn Figure 3-1 I/O expansion module internal equivalent input circuit Figure 3-1 I/O expansion module internal equivalent input circuit 3.2 Input and output signal status indication The user input terminal status can be indicated by the input terminal status LED, which is lit when the input port is closed (ON state), otherwise it is off. The status of the output port is indicated by the output status LED, when the output port is closed (ON state) (closed state between Yn and COMn), the indicator lights up, otherwise the indicator goes out, as shown in Figure 3-2.

Different output groups can be connected to different signal voltage circuits. Some output groups (e.g. Y1-COM0) can be connected to the 24Vdc circuit and powered by 24V/COM of this controller; some output groups (e.g. Y5-COM1) can be connected to the 5Vdc low voltage signal circuit; while other output groups (e.g. Y11, Y13, Y15, etc.) can be connected in the 220Vac AC voltage signal circuit. That is, different output groups can work on different voltage circuits. 7 AC-L AC-N NL SG 485485+ X0 X2 X4 X6 X10 X12 X14 X16 S/S X1 X3 X5 X7 X11 X13 X15 X17 VEICHI VC1-1614MAR +24V +5V GND 24V Y0 Y2 Y4 Y6 Y10 Y12 Y14 COM COM0 Y1 Y3 COM1 Y5 Y7 COM2 Y11 Y13 Y15 +24V +5V A A A VC-0808ENR X00 X01 X02 X03 X04 X05 X06 X07 S/S Y00 Y01 Y02 Y03 Y04 Y05 Y06 Y 0 7 COM0 AAA AC 220V AC-N AC-L Figure 4-1 Example of the electrical connection between VC1-1614MAR and VC-0808ENR 5 Extended connection 5.1 Extension busbar connection With the main module unpowered, remove the small cover of the expansion socket at the right end of the main module, then toggle the sliding catch of the main module upwards to the top, at this time plug the male socket of the expansion module, align it with the female socket of the expansion of the main module and push it in to the left, when finished, toggle the sliding catch downwards to the bottom to complete the connection of the expansion module. If more than one expansion module is connected, they can be connected one by one in turn.

The automatic addressing operation is carried out once after the power is normally applied, and the address of each expansion module remains unchanged during operation thereafter. During the operation of the PLC, the I/O expansion modules and special function modules must not be plugged in or unplugged to avoid damaging the PLC or causing abnormal operation. I/O point numbering using octal coding scheme, numbering such as: 0, 1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16, 17, 20, 21, ..., no number 8, 9. 8 The input ports of the main module and I/O expansion modules are numbered X0, X1, X2, ... X7, X10, X11, ... and the output ports are numbered Y0, Y1, Y2, ... Y7, Y10, Y11, ..., and the numbers are arranged in this order . The points are numbered in groups of 8 and any part with less than 8 points will be left blank. For example, if the VC1-1410MAR module has 14 input points, the terminals numbered X0 to X15 and X16 to X17 will not exist, and the X terminals of subsequent expansion modules will be numbered from X20 onwards; similarly, if the output points are 10, the terminals numbered Y0 to Y11 and Y12 to Y17 will not exist, and the Y terminals of subsequent expansion modules will be numbered from Y20 onwards. I/O expansion modules are numbered in increasing order according to the order of connection to the main module's expansion, corresponding to the X and Y terminals. An example of the logical numbering of the ports of the main module and the I/O expansion modules is as follows.
