Description
CI855K01 DC input wiring to AC/DC power supply and pure DC power supply
The DC input power supply range is 12~30VDC for 24VDC power supply, and 18~56VDC for 24/48VDC power supply or
100~150VDC is used for 125VDC power supply. All series 90-30 power supplies have DC input capability. The following connection information
For all series 90-30 power supplies:
Connect the+and – lines from the power supply to the top of the terminal board (+to the top of the terminal, – to the second terminal). Connect top third
Terminals to system ground.
+24 VDC output (all power supplies)
The two terminals of CI855K01 at the bottom are connected to the isolated 24VDC output, which can provide power for the input circuit (within the range of power provided)
warning
If the same DC power supply is used to power two or more power supplies of a series 90-30 PLC system,
Confirm that the connection polarity of each rack (top terminal+and the second terminal –) is consistent
Cross the positive (+) line and the negative (–) line. Potentially different results may cause personal injury or equipment damage. The same as
Each substrate must be connected to the common ground, as described earlier in this chapter
Note: Series 90-30PLCs must be installed in a protective location. CI855K01 The site should be equipped with a proper disperser
It has the capacity of heat generated by the equipment. Refer to Appendix F for details on calculating heat loss
The system design, including the production plan and wiring diagram, should be completed before the installation procedure. This section provides a base
This step by step approximates the installation procedure of a series 90-30 system. Refer to the previous section for other details of some steps
Part of the content. Try to distribute each step in order to improve the effectiveness of the program as much as possible. However, due to the system design
This sequence cannot fully adapt to the user’s system, so the user can modify this program to meet his own needs.
1. Collect charts, layouts, prints, and other information about the work.
warning
In order to avoid electric shock or damage to the user’s PLC, we recommend that the user install the PLC
Turn off all power supplies during assembly and wiring. Similarly, when some light sensitive parts are drilled and metal chips are produced
Take all electrical components away from the area when chips and iron chips are used.
2. Determine the installation position of the base plate from the layout drawing. Arrange the mounting holes using the dimensions given on the layout drawing or the “base” in the manual
Dimensions given in the chapter “Plates”.
3. Mark the mounting hole position of the base plate safety grounding wire. (Refer to “Baseplate safety connection” in this chapter)
4. Mark the opening position of module shield grounding connection (if possible) CI855K01. Refer to “Template Shield Grounding” in this chapter
(and the accompanying part).
5. Complete the arrangement of other parts of the system (mark the position of the mounting hole). Include the location of all terminal blocks used. For a

The DIN rail for the TBQC assembly is optional for some 16 point and 32 point discrete I/O modules
Plate. If TBQC is used, refer to Appendix H for detailed data. Similarly, APM and DSM templates use mounted terminals

be careful
We recommend drilling all holes before installing any element. This avoids debris and
iron filings.
6. Drill the marked holes. Use 8-32 or 4mm screws to mount the base plate.
7. Install the base plate. Use quality 8-32 x 1/2 inch or 4 x 12 mm size screws. We suggest that
Use a star shaped fixed washer and a flat washer (the star shaped fixed washer should be located between the screw head and the flat washer) to ensure that
Ensure the grounding connection of the base plate is fastened and the screws are not loose. Connect each
The grounding wire of the base plate.
8. If there are expansion or remote racks, determine the correct rack number for each rack, and then select the rack number on the base plate
The DIP switch sets the rack number. For details on setting DIP switch, please refer to the chapter “Base plate”. Through system compilation
The program assigns rack numbers because they correspond to the system configuration and program memory addresses..
9. If there is more than one base plate (rack) in the user system, connect the I/O bus expansion between the I/O bus expansion connectors
The expansion connector is located at the lower right end of the base plate. The cables from one substrate to another form a “daisy chain”
connect. This connection is made by a pair of connectors at one end of the cable. Therefore, when the cable is plugged into a base plate
The second connector at this end of the cable provides a socket for connecting with the next cable. I/O bus extension
For the data sheet of expansion cable (IC693CBL300, etc.), refer to the chapter “Cable”, with wiring diagram.
