Example of digital output connections
6.7 Card option - 2 digital inputs
6.7.1 Preamble
This card has two independent digital inputs, each programmable in impulse or synchronisation mode
via the communication interfaces available.
•
Pulse mode: when the input is configured in Pulse mode, the received pulses are multiplied by the
weightings of the pulses on this input and are then summed in an accumulator. The pulse weighting
is adjustable from 0.0001 to 999,9999
•
Synch Input mode: the input is used to synchronise the recordings or to manage alarms. It can
also be used to synchronize the ENERIUM’s internal clock; in this case when a pulse is detected at
this input, the ENERIUM automatically returns its internal clock to on the hour, if the internal clock is
less than 5 seconds adrift from on the hour.
The detail of the management of each of the two digital inputs is defined in document MSO-7423 -
Mapping and control words, available from the Enerium website at (http://www.enerium.enerdis.com).
