Brief Introduction

UT-734

UT-734 PCI converter card, compatible with RS-485 standard, can convert single-ended PCI signal to balanced differential RS-485 signal, with fast transient voltage suppressor protector, this protector is designed to protect RS-485 interface, adopt TVS (TRANSIENT VOLTAGE SUPPRESSOR) transient voltage suppressor, Under normal conditions, the TVS tube is in a high resistance state. When the two ends of the TVS tube are subjected to an instantaneous high-voltage shock, it can reduce the impedance at both ends at a very high rate and absorb a large current, thus clamping the voltage at both ends at a predetermined value and protecting the circuit components from damage due to transient high-voltage shock. This protector effectively suppresses lightning (LIGHTNING) and ESD, provides 600W of lightning surge protection power per line, as well as surge voltages and transient over-voltages generated by various causes on the line, and the extremely small inter-pole capacitance ensures high-speed transmission over the RS-485 interface.
