DM670TM FIELD/WALL MOUNTED TEMPERATURE DISPLAY 

- **UNIVERSAL RTD OR THERMOCOUPLE INPUT** 

**BATTERY POWERED, USB AND NFC INTERFACE** 

**DUAL RELAYS, MAX/MIN INFORMATION** 

**USER-SET DISPLAY MESSAGING** 

- **5000 POINT LOGGER* (USB or COMPATIBLE ANDROID DEVICE)** 

## **INTRODUCTION** 

The DM670TM series of battery powered indicators accept RTD or Thermocouple temperature sensors and display the sensor temperature in °C or °F 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 two changeover relays can be used together with the messaging and alert to provide switching at userset switch points. In addition to this, on-board datalogging is also available to record process details up to 5000 points. 

## **FEATURE HIGHLIGHTS** 

## **DUAL RELAYS** 

The instrument is equipped with 2 volt-free changeover-type relays, operating independently. The user may select one of seven actions, including deviation, latched or non-latched operation, with fully adjustable set-point and hysteresis. The Relays may be turned off if not required to extend battery life. An option is provided to trigger an alert-event when a relay contact is on. 

**DATA LOGGING FUNCTION** (See Logger* entries, check website for latest Android version compatibility) DM670TM also provides a powerful data logging function. The log points can be set up to 5000 points, each point is time and date-stamped together with temperature and relay state information. The log rate is selectable in steps. The start of log can be delayed if required. Either fixed or rolling logs may be performed. 

Two methods of reading the log are available. The USB configuration reads the log and allows the user to save to a text file for export to other programmes. While the NFC android interface allows data transfer to compatible android phones or tablets by using the downloadable App, the data can be graphed and forwarded by email, Bluetooth etc. The NFC interface is also capable of starting a new log with different log period and modes. 

## **BATTERY POWERED** 

The instrument is powered by a single 3.6 V lithium battery. The battery life is dependent on the number of active features such as the relay contacts and alert LED. Battery life 1 year minimum (longer depending on options selected) 

## **REAL-TIME CLOCK** 

Date and time-stamped maximum, minimum and average temperature values, as well as relay on and relay off data, is recorded and can be displayed along with the current time and date. The Real Time Clock is also used to record the data logged points.
