Type: IR

Compatible with TTL/RS485 standard, can convert TTL signal into differential RS485 signal, half-duplex communication. Compatible with 3.3V~5VTTL signal level, with overvoltage prevention circuit on the power supply end
The on-board integrated power supply isolation can provide stable isolation voltage, and the isolation terminal does not require additional power supply. The on-board integrated digital isolation can perform signal isolation and has the characteristics of high reliability, strong and low power consumption
Onboard TVS (transient voltage suppressor), which can effectively suppress surge voltages and transient peak voltages in the circuit, and protect against Lightning-and static electricity
On-board self-restoring fuses and protection diodes ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve impact resistance
The onboard RS485 output terminal has a 120R resistor, which can be switched and enabled by welding. It adopts black immersion gold technology and is compact in size, making it easy to integrate and embed
