diustou Industrial SP3232 Isolated RS232 to TTL Serial Converter Module with ABS Enclosure DIN Rail Mount with OPTO-Protection 3.3V/5V DB9 Male

• [Chip Scheme] Adopting industrial-grade chip SP3232 chipset, good compatibility, achieve TTL 232 interface direct mutual transfer communication, baud rate support range: ≤ 150K bps.
• [Interface protection] TTL and RS232 RXD, TXD, RTS, CTS pins with overcurrent protection, electrostatic protection circuit, DB9 male interface and 5.0mm screw terminals do not damage the interface.
• [Voltage Isolation Circuit] DC-DC power isolator and digital isolation chip to ensure the stability of the internal circuit level and more accurate signal transmission.
• [Signal Compatibility] 5V power supply is required when using TTL terminals, TTL signal terminal output signal level is 5V (same as power supply voltage), input signal level is 5V (compatible with 3.3V signal input).
• [Optimised for use] ABS case with lugs and DIN rail mounting, five on-board LEDs to indicate the power status of the circuit and the status of the signals being sent and received.

Adopt original chip SP3232, high-speed communication is stable, reliable, good compatibility

Adopt DB9 male interface and 5.0mm screw terminal, smooth insertion and extraction, sturdy and reliable
