The DM650LP loop powered process switch and indicator, accepts a (4 to 20) mA signal and displays the process value in the appropriate engineering units on a 6-digit LCD display. The instrument offers an advanced display mode allowing the user to also display one or two (1 to 32) character messages. In addition, the user may select an alert event to occur when the temperature is within a band. The change-over relay can be used together with the messaging and alert to provide switching at user set switch points. This means the instruments can be used as a loop powered process switch depending on which type of process the (4 to 20) mA loop is measuring.  An on board data logging function is also available to record process details at up to 5000 points. In this case a battery needs to be fitted so the log can continue to be monitored in case of loop failure.
