    Model Indication and How to Order EX140-SMJ 1 Output type 16 outputs, NPN (positive common) / sink Fieldbus CC-Link Summary of Product parts Element Description Communication terminals (DA, DB, DG) To connect the CC-Link line with a CC-Link-dedicated cable. Power supply terminals (24 V, 0 V) To supply power to solenoid valves.

  • Page 9: Mounting And Installation

    Mounting and Installation ■Communication wiring The connection between a CC-Link-dedicated cable and an SI unit communication terminal for CC-Link is shown below. The hole diameter for the screwdriver entry to access the terminal screw is 6 mm. (The terminal screw is an M3 cross head screw.) (1) Be sure to connect each signal line to its dedicated terminal.
  • Page 10 (4) The CC-Link-dedicated cable’s shield wire (SLD) should be connected to the “FG” terminal of the SI unit. For the EX140-SMJ1, the "SLD terminal" and "FG terminal" are common. Therefore, connect 3 wires to the "FG Terminal" as shown in Fig. 4. Fig.

  • Page 11: Power Supply Wiring

    ■Power supply wiring Connect the power supply wiring to the solenoid valve power supply terminals and to the SI unit control power supply terminals. Although the power supply consists of two separate systems, it is possible to use either a single power supply or separate power supplies.
  • Page 12 ○Switch setting The setting for the station number and communication speed can be carried out using the rotary switches under the SI unit cover. The setting for HOLD/CLEAR can be carried out using the DIP switch under the SI unit cover. The settings must be carried out with the power supply for the SI unit turned off.
