diustou Industrial Grade RS422/485 to RS232 Serial Module DB9 Interface Support 2M Baud Rate with Isolator Protection Circuit Aluminum Alloy Case

Support RS232 and RS485/RS422 signal bi-directional automatic conversion, no need to manually switch the receive - transmit control, suitable for full-duplex (RS422) and half-duplex (RS485) communication scenarios, compatible with industrial equipment, sensors and control systems. ^^ Adopting original SP3232 and SP3485 chips, it supports up to 2Mbps baud rate (experimental environment), which makes data transmission stable and reliable, and meets the needs of high-speed communication. ^^ DC-DC power isolation + digital isolation chip, blocking ground loop interference; RS232 terminal and RS485/422 terminal built-in overcurrent and surge protection, lightning gas discharge tube (GDT), transient voltage suppression tube (TVS) and self-recovery fuse ^^
RS232 terminal: standard DB9 interface, suitable for traditional serial devices;
RS485/422 terminal: 5.08 mm plug-and-play terminal, support for quick installation; on-board 2 LED indicators (232 receiving lamp, 485/422 receiving lamp), real-time visualization of data transmission status. ^^ Oxidized frosted aluminum alloy shell, good heat dissipation, impact resistance, precise openings for industrial installation; 5V single power supply (RS485/422 terminal requires external power supply)
