Features

Digital or Analog I/O

The PC99 is available with either digital (DeviceNet or RS-485) or analog I/O allowing for straightforward integration into new or retrofit applications. In-situ tuning and component diagnostics are enhanced through the device’s standard Ethernet user interface accessible via virtually any PC with a web browser. The PC99’s bright, 4 digit rotatable display provides easy viewing of the device’s IP address as well as process pressure, flow, and temperature.
