UT-2501 adopts optoelectronic isolation technology, it fully isolate the electric and ground wire loop circuit between both sides of RS-232 device, protects the communication device from power ground wire loop circuit and surge interference. The built-in instant voltage protector protects CANBUS interface; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) to improve the communication reliability and stability; at the same time, UT-2501 use dual wire balance transmission instead of RS-232 port single side transmission; this greatly enlarge the communication distance. In the field of asynchronous RS-232 point to point in special line, UT-2501 meets the requirement of port protection or distance extension.

UT-2501 is mini size design, there is no special requirement on wire; the consumption of external power is less than 50mA, you can plug it directly into RS-232 port, convenient for using.

UT-2501 series is widely used in point to point RS-232 communication, RS-232 long distance control system, SPC exchange terminal billing, and satellite receiver.
