Product Description

The Modbus Wi-Fi / Ethernet / Serial Gateway is a converter that provides a bridge connection for devices on Modbus RS-485 Serial networks with those on Modbus TCP networks allowing for seamless integration.

Supporting up to 10 Masters on either of the hardwire Ethernet or Wi-Fi Interfaces and up to 32 slave devices on the RS-485 serial interface (R1 port). The gateway has a second serial port (R2) that can be connected to a Modbus RTU Master. The Modbus RTU Master and Modbus TCP Master can communicate simultaneously with the slave devices.

Serial data rates up to 115.2 kbps are supported ensure maximum network flexibility.

The Modbus Wi-Fi / Ethernet / Serial Gateway is built for use in Industrial environments, featuring a slim, ultra-compact DIN rail mounting design.

It operates from either 24Vac or 12-24Vdc power supply voltages and has pluggable terminal block connectors for quick removal and re-install. An external power supply, sold separately, is required.

Each gateway is easily configured through its web server interface.

The Wi-Fi antenna is removable and has a standard SMA connector allowing for an external antenna to be connected, if required.
