Thiết bị chống sét tín hiệu RS-232 Maiwe MWE232-A
The MWE232-A/B/C series port isolator has built-in photoelectric isolation, and the interface complies with EIA/TIA RS232 standards. It can provide isolation protection of up to 2500Vrms, with static and lightning protection, which can improve the reliability and stability of communication systems. The passive models(MWE232-A and MWE232-B) can be port-powered through each side of the serial port, no need the external power supply. The specific serial port protection circuit support hot plugging. The isolator hardware adopts a low-power and wide temperature design, can operate stably in temperature environment of -35 ℃ to+85 ℃, and can be widely used in equipment such as motors, transformers, relays, or scenarios with high amplitude transient interference.
