Antaira STM-604C Modbus TCP to 4-Port Serial RTU/ASCII Gateway, Class 1 Div 2 Rated

Antaira Technologies' STM-604C industrial-grade Modbus gateway manufactured allows legacy Modbus RTU/ASCII devices to connect to a Modbus TCP network. The unit configures as either a Modbus serial master or slave. The STM-602C features two redundant Fast Ethernet ports for reliability. The dual serial ports, configurable as RS-232, RS-422, or RS-485, connects to standard serial devices and networks. The DIN-rail mountable gateway meets UL, Class 1, Division 2 specifications, and extended temperature making it perfect for industrial and harsh environments where Modbus is found.

Key Features

  • 2 Fast Ethernet (10/100TX) ports for redundancy
