STRIDE® Modbus Gateways provide the bridge between Modbus RTU/ASCII (Serial) products and Modbus TCP (Ethernet) products. The gateway converts bidirectionally between Modbus RTU or Modbus ASCII protocols and Modbus TCP. The compact STRIDE gateway features 1 or 2 10/100 Mbps Ethernet ports and 1, 2, or 4 Industrial serial ports. The Ethernet ports each support up to 16 TCP devices, client or server. Serial ports each support up to 128 slave devices or 1 master device and provide a high serial isolation voltage of 2kV. There is a DIP switch selectable termination resistor for the RS-485 mode. STRIDE gateways, with compact metal housings, have a wide temperature range of -40 to +75 deg C and a Class 1 Div 2 Hazloc rating (UL61010). The three models of the STRIDE MB Gateway are priced from $185.00 and have a 5-year warranty.
