HD67630-MSTP-A1 BACnet MS/TP Slave to S7comm Converter with RS485 and Ethernet in DIN Rail Type A Housing

HD67630-MSTP-A1 BACnet MS/TP Slave to S7comm Converter with RS485 and Ethernet in DIN Rail Type A Housing. 

The HD67630-MSTP-A1 is a compact and durable industrial protocol converter designed to establish communication between BACnet MS/TP Slave devices and S7comm-based systems, typically used in Siemens PLC environments. Its robust features and compatibility make it a reliable solution for projects requiring seamless integration of building automation with industrial control systems.

Operating as a BACnet MS/TP Slave and Ethernet S7comm server, the device acts as a transparent translator between field devices and Siemens automation platforms such as S7-300, S7-400, and S7-1200. Its narrow DIN-rail mountable Type A housing is ideal for installations where space is limited, while maintaining full industrial-grade performance.

The wide operating temperature range from -40°C to +85°C ensures that the HD67630-MSTP-A1 can operate reliably in harsh industrial environments. The unit is powered via 8–24 VAC or 12–35 VDC and offers electrical isolation for improved signal integrity and equipment protection.
