AJMRTC industrial galvanic isolated TTL to RS422 converter adopts integrated power and signal isolation design to cut off ground loop interference in complex industrial environments. It converts single-ended TTL UART signals into balanced differential RS422 signals for stable full-duplex serial transmission. It supports 3.3V and 5V TTL devices and comes with multi-layer surge and electrostatic protection. The 35mm DIN rail ABS housing allows neat cabinet installation. The onboard terminating resistor can be enabled or disabled by jumper. It is widely used for PLC communication, industrial sensors, Modbus networks, long-distance data acquisition and factory automation control systems. Controller and peripheral devices are not included.
