Model DMT-1040, DMT-1024 & DMT-1042

 

 

Description
The DMT-1040 is a programmable multifunction transducer with an RS-485 bus interface (MODBUS®). It supervises several variables of a polyphase electrical power system simultaneously and generates 4 proportional analog output signals. The RS-485 interface enables the user to determine the number of variables to be supervised (up to the maximum available). The levels of all internal counters that have been configured (max. 4) can also be viewed. Provision is made for programming the DMT-1040 via the bus. A standard EIA 485 interface can be used, but requires a load resistor for the bus. This interface is needed for bus operation to configure the device address, the baud rate, and possibly increasing the telegram waiting time defined in the MODBUS® protocol (if the master is too slow).

The DMT-1024/1042 series multifunction programmable transducers simultaneously measure several variables of a polyphase electric power system and process them to produce 2 or 4 analog output signals. Also 2 or 4 pulse outputs are available for signaling consumption quantities or limit thresholds. For two of the limit outputs, up to three measurands can be logically combined.

DMT-Series transducers are equipped with an RS-232 serial interface to which a PC with the DMT-Config software can be connected for programming or accessing and executing useful ancillary functions. Among the items which can be programmed are: all common types of electrical systems, the measured variable, rate values for input variables, output variable response characteristics, etc.

Ancillary functions include a power system check, a provision for displaying the measured variable on a PC, the simulation of the outputs for test purposes, and a facility for printing nameplates. The transducer fulfills all the essential requirements and regulations concerning electromagnetic compatibility (EMC) and safety (IEC 1010 and EN 61010). It was developed and is manufactured and tested in strict accordance with the quality assurance standard ISO 9001 and carries CE and CSA certifications.

MEASURED QUANTITIES (per-phase and polyphase)

  • Current and Voltage (RMS).
  • Active, Reactive and Apparent Power.
  • Active, Reactive & Apparent Energy (consumption).
  • Cos Ø, Sin Ø, Power Factor, Frequency.
