GW211W-MB 2 port serial RS-232 and RS-422/RS-485 Modbus RTU to Modbus TCP Wireless Gateway

The GW211W-MB is a Wi-Fi / Ethernet / Serial MODBUS Gateway bridging RS-232 and RS-422/RS-485 Modbus Serial RTU Data to Modbus Ethernet IP networks either via hardwired RJ45 Ethernet or a wireless connection. The Modbus Gateway works with standard
Modbus Slave devices, such as PLCs, IoT Sensors, Energy meters (AMRs), Solar Inverters, Wind Turbines, IO Modules, Flow Meters and more. The Modbus Gateway is built for use in light industrial environments and features a compact wall-mount design. It operates from 9-32VDC power supply voltages with terminal block connectors and is easy to configure through its web GUI interface.
