Description of the connection diagram

1. Power connection

• Terminal: +V and GND
• Source: Stabilized 12V (24V) DC power supply
  (see Figure 2.)

2. RS485 interface connection (Modbus RTU)

• Terminals: A+, B-.
• Topology: Linear bus (not star).
• Number of connectable devices: up to 32
• Terminators: At the end of the physical bus (the last device in the line), a terminating resistor (usually 120 ohms) must be installed between terminals A+ and B-.

3. Connecting analog inputs (I1-I4 and V1-V4)

• Terminals: For each channel: Ix and Vx (signal) and GND - common for analog inputs.
• For sensors with current output (4-20 mA):
  • (+) sensor --> Ix module.
  • (-) sensor --> module GND.
• For sensors with voltage (0-12V) (0-24V):
  • (+) sensor output --> module Vx.
  • (-) sensor output --> module GND.
    (see Figure 2.)

4. Connecting digital inputs (IN1 - IN8)

• Terminals: INx and common GND.
• «Dry contactконтакта connection (button, limit switch):
  • One button contact --> INx.
  • Second button contact --> GNDI.

5. Connecting loads to digital (relay) outputs (OUT1 - OUT8)

• Terminals: For relay circuit: --> COMx (common), NOx (normally open), NCx (normally closed).
  (see Figure 2.)

Connecting and configuring the module in the web application of the iОmatex online service

1. Ensure that the IOMX G-Box 023D gateway is connected to the Ethernet/Wi-Fi network and registered in the iOmatex system.

Figure 3. Connecting the iOMATEX NANO ExBD-08/16-12 (24) module and the IOMX G-Box 023D gateway to the RS485 interface and the iOmatex network.

2. Connect the iOMATEX NANO ExBD-08/16-12 (24) module to the gateway via RS-485 (lines A and B, observe polarity).
   

   *(Up to 32 modules can be connected to one gateway via RS-485).*

3. Add the module in the iOmatex web interface
