MODEL277A-M

RS-232 to optic fiber converter, multi-mode 2Km, 5VDC, SC/ST optional.

The Model277A allows the transparent transmission of the serial RS-232 port via a multimode fiber optic cable, is perfect for connecting RTU devices to a host or SCADA controller. With the opto-isolation and robust housing, the Model277A is ideal for use in projects with special electromagnetic and immunity requirements. The kit includes an external 5VDC power supply and converter instruction manual.
