Serial Converters & Repeaters

Serial Converters & Repeaters

Converting or repeating serial data is made easy by Westermo.

Westermo manufacture an extensive range of industrial serial converters and repeaters. Whether you wish to convert between Ethernet, RS-232 and RS-422 or RS-485, extend a serial network, provide a gateway between Modbus RTU or ASCII and Modbus TCP, convert between 2-wire and 4-wire applications, or even provide isolation between serial devices, Westermo has a solution. Our industrial serial converters / repeaters are designed for use in harsh environments and ensure rugged, reliable communications.

    MD-45-LV RS-422/485 Converter

    RS-232 to 422/485 Converters

    MD-45 LV

    MD-45 is used as an interface converter between RS-232 and RS-422/485 or when point-to-point communication is needed at data rates up to 115.2 kbit/s. The device can communicate on 2-wire or 4-wire cable up to 1200 metres (4000 ft). In multidrop applications the MD-45 supports up to 32 connected devices on the bus. With 2-wire systems the communication direction is controlled by the data flow, i.e. the converter detects the data and switches the communication direction depending from which side the data has been sent. This makes it possible to connect equipment that cannot generate handshaking signals.

    RS-422/485 Repeater

    RD-48 HV

    RS-422/485 Repeater
    2 x 4-position detachable screw terminal, 300 bit/s to 1.5 Mbit/s

    The RD-48 is a multi-purpose device that allows the extension of networks beyond the normal scope of the RS-422/485 standards. The device can be used as a repeater to extend the maximum distance of a network beyond 1200 m or the number of devices above 32. It can also swap between 2 and 4 wires or be used to build a structured and isolated network.

    Dual Serial to Ethernet Converter

    EDW-120

    Dual Serial to Ethernet Converter
    1 x RS-232 9-pin D-sub, 300 bit/s to 115.2 kbit/s
    1 x RJ-45, 10 Mbit/s or 100 Mbit/s

    The EDW-120 is a dual serial to Ethernet converter designed to allow RS-232 serial devices to communicate via TCP/IP Ethernet networks. DIP switches can be used for configuration of Ethernet port settings if required, and the password protected web interface is used for all other settings. Diagnostic information can be accessed via a Telnet session with more basic information offered on LEDs.

    RS-232 to 422/485 Converters
    1 x RS-422/485 4-position detachable screw terminal, 300 bit/s to 115.2 kbit/s
    1 x RS-232 9-pin D-sub, 1200 bit/s to 115.2 kbit/

    The MDW-45 is a simple serial converter allowing RS-232 and RS-422/RS-485 systems to be connected. DIP switches are used for all configuration options which makes the unit simple to install.

    The MDW-45 is designed for use in heavy duty industrial applications. The wide power range, galvanic isolation, transient protection and the design of the termination and fail safe guarantees communication in the worst environments. Only industrial grade components are used which gives the MDW-45 an MTBF of 1,000,000 hours and ensures a long service life. A wide operating temperature range of –40 to +70°C (–40 to +158°F) is achieved using no moving parts.
