The SC81 Serial Communications RS-422/ 485 Transmitter/ Sensor can wirelessly communicate RS-422/ 485 serial outputs to system gateways for logging and integration in control systems. The SC81 is compatible with instrumentation/ sensors with differential serial outputs representing measuerment data.The SC81 offers a dual-mode power option, allowing the sensor to use an AC wall adapter for best performance, or up to 4 months operation using the built-in battery at a slower sample rate.
