3KV Photoelectric Isolation RS232 Isolator, Model: FCI-138 by FCTelecom

The basic function of this model FCI-138 is an RS232 isolator, which uses serial port stealing technology for passive conversion. Its internal interface has electrostatic protection and has strong anti-interference characteristics. The threewire 3KV isolation technology is used to protect the RS-232 serial interface equipment to the greatest extent, avoiding the damage to RS-232 equipment caused by harsh environments such as ground loop voltage, surge, induced lightning strike, static electricity, and hot pull. The product is plug and play, with strong environmental adaptability, and the rate is as high as 256Kbp. Can amplify and extend the serial port signal.

Feature:

– RS232 baud rate 300-256Kbps adaptive;
– The isolation voltage is 3000V, and the serial port is used to steal electricity, which improves the applicable surface;
of the equipment;
– Compliant with EIA RS-232 and CCITT V.28/V.24 asynchronous protocols;
– Isolation pin: receive (RX), send (TX), ground (GND, 5P) three-wire isolation;
– Two RS232 ports have TVS protection to suppress static electricity and surge;
– DB9 connector: use DB9 male/female connector on both sides;
– Fully transparent communication, users do not need any debugging, plug and play;
– Wide temperature type: working temperature -40℃~ +85℃;
– All models have passed 100% oven test;
