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.*
Because the TC1520 can be multi-dropped on the electrical side (RS-485), it
is ideal for poll and response applications such as SCADA and Process
Control. It will support one Remote Terminal Unit via the RS-422 interface.
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.
The TC1520 is compatible with all popular types and sizes of multimode
(850nm/1300nm) or single mode (1300/1550nm) fiber optic cable. Fiber optic
connectors are ST or FC. The electrical connectors are terminal blocks.
Power is 12VDC or 115/230VAC with an external power cube. An extreme
temperature version (-20°C to 70°C), Model TC1520T, is also available.

The TC1520 is typically used to link various
process control systems in manufacturing plants, refineries, etc. In addition, it is often
used to connect Remote Terminal Units to SCADA hosts. They are also frequently used in
harsh environments because of its fiber optic benefits. This makes it simple and low cost
solution to electrical/radio frequency interference and ground loop problems. Data
security is also assured because fiber optic cable is virtually impossible to tap without
