HD67164-422-A1 – Modbus RTU Master to SNMP Agent Converter with RS422 and DIN Rail Mount

HD67164-422-A1 – Modbus RTU Master to SNMP Agent Converter with RS422 and DIN Rail Mount. 

The HD67164-422-A1 is an advanced and compact industrial gateway that enables Modbus RTU Master devices to exchange data with SNMP-based management systems, such as SCADA platforms, BMS, or networked servers. It acts as a translator between the two protocols, ensuring bi-directional information exchange across field and monitoring levels.

This model features a slim housing (type A) designed for DIN rail mounting, and uses an RS-422 interface for long-distance serial communication with higher immunity to electrical noise. The HD67164-422-A1 is an excellent choice for industrial environments where reliability and compactness are key.

The converter supports up to 1024 bytes of data for both reading and writing. It provides triple galvanic isolation between Serial ↔ Power Supply, Serial ↔ Ethernet, and Power Supply ↔ Ethernet to ensure data integrity and device protection in electrically harsh conditions. The wide operating temperature range from -40°C to +85°C further confirms its industrial-grade performance.
