Isolates LAN⇔RS-422/485 signals using an optocoupler (with a withstand voltage of 2000V) and has a built-in AC power supply that supports wide input.
- 2000V signal isolation between LAN and RS-422/485 via optocoupler - Built-in wide input AC power supply (AC85-264V) - Automatic detection of 10 Base-T/100Base-TX, enabling connection to Ethernet LAN or the Internet - Supports Modbus TCP master mode and Modbus TCP slave mode - In master mode, it can register the IP addresses of 8 Modbus TCP slaves based on the range of connected Modbus IDs - In slave mode, it can connect to up to 10 Modbus TCP master devices simultaneously for shared control - The automatic scanning function of Modbus registers in slave mode speeds up responses to master requests - Usable in temperatures from -20 to 60°C, making it suitable for cold environments - Options available for 35mm DIN rail mounting or wall mounting (SI-485MB2) - Can be fixed to the wall with screws from the top of the unit (SI-485MB2-L) - Lead-free environmentally considerate design

basic information
The SI-485MB2 is an isolated model of a gateway that can bi-directionally convert the Modbus RTU/ASCII protocol using a serial interface to Modbus TCP compatible with Ethernet LAN. The gateway processing firmware supports both Modbus TCP master mode and Modbus TCP slave mode, and it is compatible with the conversion of all current Modbus RTU/ASCII registers and commands. Isolation between the LAN and serial signals is achieved through opto-isolators, ensuring high reliability. It has a built-in wide input AC power supply, so no AC adapter is required. With an operating temperature range that supports minus 20°C, a robust metal housing, and compatibility with 35mm DIN rail mounting, it is a product that can be safely introduced in environments requiring reliability in FA and PA. Additionally, maintaining the same functionality as the SI-485MB2, the SI-485MB2-L adopts a wall-mounted enclosure. It can be securely fixed to the wall using screws from the top surface of the unit without any options.
