brief introduction
TCC-80I is the world's first high-speed converter with serial power supply and 2.5KV isolation protection. TCC-80I supplies power through RS-232 equipment, realizing the conversion from RS232 to RS-422/485 and isolation protection. It converts TXD and RXD signals of RS-232 into two-wire RS-485 with half-duplex or four-wire RS-422/485 with full-duplex. At the same time, TCC-80I has built-in 15 KV EDS surge protection to provide overcurrent protection. TCC-80I realizes RS-485 automatic data flow control according to TXD status of RS-232 terminal. Therefore, users do not need to control the flow of RS-485 data in the program.
RS-232 serial port power supply and photoelectric isolation
The RS-232 interface of TCC-80I is DB9-hole type, which can be directly connected to the host serial port and get power through TXD, RTS and DTR signal lines. The 2.5 KV isolation protection of TCC-80I is to convert electrical signals into optical signals through optical couplers, and then convert optical signals into electrical signals at the other end. In this case, the circuits at both ends can be completely isolated. At the same time, it can protect the equipment and transmission interface components from the damage caused by the loop to the ground and prevent the loss caused by data loss.
