Specification of

DIRIS A-20
Multifunction performance metering & monitoring device - PMD Multi-measurement
DIRIS A-20 units are performance metering and monitoring devices that provide the user with all of the measurements needed to complete energy efficient projects successfully and to provide assured monitoring of electrical distribution.
All of this information can be used and analysed remotely with the help of energy efficiency software programs.

Advantages
User-friendly operation
With its large backlit multiple-display screen with 4 hot keys, the DIRIS A-29 is easy to use.

Compliant with IEC 61557-12
Reference standard for PMDs (Performance metering & monitoring devices), IEC 61557-12 guarantees performance levels and satisfactory performance from the PMDs under the environmental conditions typical of industrial and tertiary applications.

Detects wiring errors
The DIRIS A-20 is equipped with an error correction function for TC connection.

Customisable
Additional communication and input/output modules can extend the basic functional scope of this product. Equipped with additional modules, the DIRIS A-20 can provide the user with flexibility and expandability throughout the service life of the product.
