TC1520
RS422/RS485 (2/4-Wire) Fiber Optic Modem (Async)

Compact and competitively priced, the TC1520 fiber optic modem supports RS-422 and 2-wire or 4-wire RS-485 interfaces. It transmits asynchronous data at speeds up to 500 Kbps and distances to more than 20km.

Because the TC1520 can be multi-dropped on the electrical side (RS-485), it is ideal for poll and response applications (e.g. SCADA & Process Control) in Industrial and Manufacturing environments. An extreme temperature version (-20°C to 70°C) for hostile environments is optional.

Six visual indicators are provided for troubleshooting: Power, RS-485, Driver Mode, Receive Data, Transmit Data, Optic Sync. Four DIP switches are provided for RS-485 Transition Time and Termination Resistor settings. Terminal block connectors are detachable. It supports all popular types and sizes of multimode or single mode fiber optic cable.
