Description
The LD-02 is a line split modem allowing RS-232 or RS-422/RS-485 systems to be connected. The LD-02 is designed to be used in multidrop applications over long distances using the repeater functionality, serial connection can be either RS-232 or RS-422/485. The connection between the modems is W1 a balanced current loop interface allowing distances up to 18 km (11.18 mi).
DIP switches are used for configuration options which make the unit simple to install. The serial interface is connected through a standard 9 pol D-sub or terminal block with screw connectors.
The LD-01 is designed for use in heavy-duty industrial applications. The different power options, galvanic isolation, and transient protection guarantee communication in the worst environments. The LD-01 has been tested to meet many EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial environments.
The design of the line split modem makes the LD-01 suitable for a variety of applications with various speeds and data bit options. The V and Y mode emulate half or full duplex communication between master and slaves and a bypass board can be fitted to ensure networks can’t be broken by power failure at a single point.
