1/12/2023 0 Comments Rs232 optical isolator circuitCompatibility with a wide range of operating systems, including Windows®, Windows CE, Mac OS, and Linux, makes it easy to integrate into mixed environments. The versatile FTDI chipset supports COM storage, additional user-defined features, and compatibility that most other solutions do not offer. The USB serial adapter features optical isolation circuits and surge protection to protect critical and sensitive control equipment from electrical damage, making it a viable solution for industrial serial devices. The ICUSB2321F 1-port FTDI USB to serial RS232 adapter cable with optical isolation converts an existing USB 1.1 or 2.0 port to a RS232 DB9 serial port for connecting, monitoring, and controlling serial devices. Two isolators are also provided in the receive data buffer 18 for. The COM port assignment is retained even after reboot Two isolators are provided in the transmit data multiplexer 32, one for TTY transmit data and the other for RS232 transmit data.500 W bidirectional voltage protection circuits.Integrated 2500 Vrms optical isolation circuits.100 protection against interfering radiation Electrical isolation Lightning protection. Ground loops and electrical interference may result in. Data sheet for Interface 81029, Plastic-Fiber Optic to RS232. USB to straight-through RS232 Serial Adapter Using RS-232 while taking data with your 1523 or 1524 Reference Thermometer may result in a ground loop.* Working environment: -40 to 85 centidegrade, relative humidity 5% to 95%.Add a RS232 serial port with circuit isolation to your desktop or laptop via USB. * Isolation voltage: High voltage 2.5KVrms Isolation 500VDC. * Power supply: One of TXD/DTR/RTS lead of RS232 interface. * Interface features: Compatible EIA/TIA standard RS232 UT-212 products have been widely used in electricity, insurance, telecommunications, railways, post offices, financial, banking, securities, and other industry-point programmable RS232 communications systems, UNIX multi-user systems, supervisory control systems, PBX design charge terminal, satellite receivers, ATM automatic teller machines and other fields As a result of photoelectric isolation technology, a fully isolated RS232 devices at both ends of the electrical circuit with the ground, making the side of the electrical signals into optical signals transmitted after the other, changing back to electrical signals, thereby protecting communications equipment ground loops and power surges from interference and damage, significantly improved the reliability and stability of communication systems. Such as devices A and B using the RS232 interface is connected, if A and B between the ground between the voltage difference is greater than 50V (or more often to 80V), the RS232 communication will not normal, RS 232 interface with instant 2500Vrms, 500VDC continuous peak voltage difference, but also can effectively absorb the electrostatic and electromagnetic interference protection devices RS232 interface. RS232 interface hardware communications equipment damage to be caused by more than 90% is due to both ends of the device is not common ground, all kinds of surges, lightning sensors, static electricity, hot, electromagnetic interference and other harsh environment of the RS 232 damage to equipment. RS232 to RS232 Repeater Long-distance photoelectric isolator (UT-212), RS232 serial port, also known as serial optical isolator, it uses advanced optical isolation technology, which greatly limits the protection of the RS232 serial interface device, to avoid ground loops voltage, surges, lightning sensors, static electricity, hot and other harsh environment on the RS232 equipment damage.
