TTL RS485 Serial Communication Module DIN-Rail Mount Bidirectional Interconversion with Power Isolation and Digital Isolation SP3485 Chip

TTL RS485 Serial Communication Module DIN-Rail Mount Bidirectional Interconversion with Power Isolation and Digital Isolation SP3485 Chip

• [Industrial chip] Adopting industrial chip SP3485 to realize mutual conversion of TTL level and RS485, high-speed communication, stable and reliable, good compatibility, baud rate support range: ≤ 2M bps (experimental environment).
• [Signal Optimisation] With power isolation to improve the stability of the module's internal power supply, with digital isolation chip to improve the stability of the internal signal transmission, the overall ability to adapt to more complex environments
• [Protection Upgrade] TTL and 485 terminals with overcurrent protection and surge protection to ensure stable current and voltage output, strong shock resistance, additional on-board lightning gas discharge protection circuit.
• [Detailed Optimisation] On-board automatic transmit/receive conversion circuit, no need for ‘transmit/receive’ control. There are three LEDs for power, transmit and receive, which can visually display the circuit status, additional compatibility with 3.3V TTL level inputs
• [High Quality Components] ABS housing, DIN rail mounting, with 120Ω terminating resistor, dialable cut-in/cut-out, 5.0mm screw terminals, easy wiring installation
