The HEMSA-T-014 is a PCI to 2-port RS-485/422 multi-serial card featuring high-performance photoelectric isolation. Fully compatible with RS-485/422 standards, it converts PCI signals into balanced differential RS-485/422 signals.
Equipped with a built-in photoelectric isolator, the card provides up to 2,500 Vrms of isolation voltage. It also features robust lightning and ESD protection, offering 2,000V of surge protection per wire. This circuitry safeguards against transient over-voltages and surges regardless of their origin, while the low inter-electrode capacitance ensures high-speed data transmission across all ports.
