AJMRTC industrial galvanic isolated TTL to RS485 converter supports 3.3V5V wide TTL level input. It adopts integrated power and signal isolation design to block common-mode noise and ground difference. Built-in TVS transient suppression circuit delivers 600W lightning and surge protection together with multi-isolation protection for reliable operation in harsh field environments. It features automatic direction control without extra control signal, and the 120 termination resistor can be switched on or off for long-distance wiring. It uses screw terminals for RS485 connection and supports baud rates from 300bps to 115200bps with maximum transmission distance up to 1200m. Widely used for Modbus RTU networks, PLC commissioning, serial sensors, instrumentation and embedded data acquisition.
