Hardware Installation

Before powering the device, please follow the steps below:

  • The power connection diagram of the device is provided in the Power Connection section. Care should be taken with the polarity of the power connection.

  • The RS485 communication connection diagram of the device is provided in the RS485 Connection section. Incorrect connections at the communication port can cause permanent damage to the devices.

  • The RS232 communication connection diagram of the device is provided in the RS232 Connection section. Incorrect connections at the communication port can cause permanent damage to the devices. The VCC output is V.

  • To use the optical isolated digital inputs on the device, the GND connection must be made to the COM input. After that, each input channel can be used by triggering positively with 10-30 VDC. An example connection diagram is provided in the Digital Input Connection section.

  • The relay outputs on the device are normally open (NO) terminals. The COM ports (OCM1 and OCM2) are internally connected to the terminals (OCM1 for Output 1 and Output 2, OCM2 for Output 3 and Output 4). When the output is activated, the terminal starts to transmit the signal from the COM port. If the required output power is higher than what the device supports, it is recommended to use external relays or contactors. An example connection diagram is provided in the Digital Output Connection section.

  • Analog inputs 1 and 2 can be used for measurement with nominal values of 0-10 VDC or 4-20 mA. Example connection diagrams are provided in the Analog Input (0-10 V) Connection and Analog Input (4-20 mA) Connection sections.

  • The analog output can be used for 0-10 V control systems. An example connection diagram is provided in the Analog Output (0-10V) Connection section.

After this step, ensure that all cable connections are as shown in the provided diagrams, and then power the device.

If the connection is correct, the power LED will light up.
