USR-DR134 - RS485 to Ethernet - PUSR

Compact RS485 to Ethernet Converter

The PUSR USR-DR134 is a compact serial to Ethernet converter designed to connect RS485 equipment to an IP network. It allows for easy integration of Modbus devices, sensors, meters, or PLCs into an Ethernet architecture.

RS485 to IP network conversion

The USR-DR134 provides transparent bidirectional transmission between RS485 and Ethernet. It is suitable for industrial applications, telemetry, supervision, automation, and remote maintenance.

Protocols and Modbus

The converter supports TCP Server, TCP Client, UDP, and HTTPD modes. It can be used as a Modbus RTU to Modbus TCP gateway, facilitating the integration of RS485 equipment into SCADA systems or industrial software.

Simple installation

Its compact form factor and pluggable terminal block simplify installation in an enclosure or directly near the serial equipment. The VCOM function also allows for extending a serial link via the network.

Industrial design

The USR-DR134 operates from -40 °C to +85 °C and includes monitoring functions, automatic reconnection, and EMC protection to ensure stable communication in demanding environments.
