Both system options are completely field configurable and do not require the support of a PLC programmer or engineering services.

The main screen displays the current reading and alarm status of up to 8 field devices with tabs to navigate to additional screens. A USB port is located on the back of the unit for expanded alarm history and data logging in high-density applications. Â
