• Definition of the digital outputs G and H, respectively E to
H, either to produce an output impulse (counter impulse)
for measuring Ah, Wh, Varh and VAh or to monitor a limit.
2 limit monitor outputs (G and H) permit up to 3 measure-
ments each to be logically interlocked.

Provision is also made for the following ancillary functions:
• The power system check
• Provision for displaying the measured variably on a PC
monitor
• The simulation of the outputs for test purposes
• Printing of nameplates
6.3 Operation of the binary outputs
The binary outputs are electrically isolated from all other
circuits via an optocoupler.
They therefore require an additional power supply to energise
the output circuits.
Outputs
E, F, G and H in the case of SINEAX DME 424
and outputs
G and H in the case of SINEAX DME 442 are
available (see Section “Electrical connections”).
External power supply: 8 … 40 V
Output current:
ON 10 … 27 mA
OFF
≤
2 mA

Without
hardware setting change
The PC software DME 4 (Order No. 146 557) and a
programming cable (Order No. 980 179) are needed in order
to reprogram the device. The reduced accuracy resulting
from this change can be determined by printing a type label
(see Fig. 14 and 15).
