The I/O module OB-216 is designed to control devices based on an analog signal, collect data from various sensors and transfer this information via MODBUS protocol.

Additionally the OB-216 provides the possibility of smooth control. It integrates perfectly with EM series controllers from Novatek-Electro.


OB-216 supports the following types of sensors:

  • sensors with voltage output (0 – 10V)
  • sensors with DC output (4 – 20mA, 0 – 20mA)
  • temperature sensors of different modifications
  • all kinds of Arduino sensors
  • “dry contact” sensors with open collectors
  • 1-Wire, I2C sensors

OB-216 can to operate as:

  • a temperature controller for refrigeration and heating units
  • a protocol converter for refrigerating controllers – UART (TTL) into MODBUS (RS-485)
  • an equipment control unit by analog output 0-10V or 0-20 mA

The device can also monitor the state (closed / open) for sensors of security, alarm, additional contacts of switch position, machine operation.


OB-216 can perform such logical operations as:

  • load control according to the set thresholds;
  • linear signal conversion from 0-10 V to 0-20 mA (4-20 mA) and vice versa.
RS-485 interface provides the device's interaction with other PLC (programmable logic controller) based on free logic for the MODBUS Protocol.
User-friendly setup wizard via the Overvis cloud platform will be available when using this device with PLC EM-481/486 from Novatek-Electro.
