Description
TCP to RS485 gateway – Modbus TCP / RTU
The Serial Broker 1000 (SB1000) is a compact and flexible gateway for seamless conversion from Modbus RTU to Modbus TCP, BACnet and MQTT. The unit mounts on a DIN rail and is ideal for building automation, industry and technical installations where you want to integrate existing Modbus RTU-based devices into an Ethernet-based network. A highly intuitive user interface makes setup easier than on other products.
Flexible applications
Modbus TCP to RTU gateway
Connect Ethernet-based systems to RS485 devices.
Modbus RTU to TCP gateway
Make existing RTU installations available over IP.
RTU to RTU
Signal splitter: share slaves between a Modbus RTU master and a Modbus TCP master
Signal booster / repeater
Baud rate converter
Virtual COM port over TCP/IP
This makes the SB1000 a very flexible tool when modernising older plants or integrating different systems.
On the Ethernet side we support Modbus TCP, BACnet and MQTT.

Datasheet
Live demo
PS: The live demo is a device running at our lab. It is liimited to 2 simultaneous connections.
If the connection currently is in use, please try again at a later time.
When modifying settings, such as name, location ,etc, this will be visible to other guests.
The device resets its settings after 10 minutes of inactivity.
There is a Belimo 22DTM-16 connected to RS485-1, device ID #9.
