Product Description:

 UT-211 RS-232 serial port photoelectric isolator, also known as serial isolator (ISOLATORS), using state-of-the-art optical isolation technology, greatly limits to protect the RS-232 serial interface device, to avoid ground loops damaged the voltage surge induced lightning, static electricity, hot-swappable harsh environment on the RS-232 devices. 

RS-232 interface damage to communications equipment hardware damage caused by more than 90% of both ends of the device is not common ground, all kinds of surges, lightning sensors, static, hot-swap, electromagnetic interference and other harsh environment of RS -232 equipment damage.Such as devices A and B using the RS-232 interface is connected between the ground between the A and B voltage greater than 50V (often more than 80V), RS-232 communication will be abnormal, RS 232 interface with instant 2500Vrms continuous 500VDC peak voltage difference can effectively absorb electrostatic and electromagnetic interference protection device's RS-232 interface. 

Optical isolation technology, completely isolated from both ends of the RS-232 device electrical ground loops, so that the side of the electrical signals into optical signals later spread to the other, in the change back to an electrical signal, thereby protecting communications equipment from interference and damage to the power supply ground loops and power surges, and significantly improve the reliability and stability of the communication system. 

UT-211 products have been widely used in electricity, insurance, telecommunications, railways, post office, finance, banking, securities, programmed and other industry point-to-point RS-232 communication system, UNIX multi-user systems, monitoring and control systems, PABX meter fee terminal, satellite receiver, ATM ATM field.
