DM720 - Panel Mounted Loop Powered Indicator

Product Image

The DM720 is a compact panel mounted loop powered indicator that is designed to connect in series with a 4/20mA current loop and display the value in engineering units.

The DM720 is housed in a 48x24mm DIN standard panel mount case and provides 10mm high LED digits . The engineering range is programmed by using easily accessible push buttons. The design of the product means no external power supply is needed and it requires less than 5V from the current loop.

 

DM650/LP - Loop Powered Indicator With Data Logging, Alarm & Messaging

Product Image

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.

Additional to the messages, 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. For example temperature or pressure.
 
In addition to this, an on board datalog 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.
