Digital inputs

SAM600 modules have four digital input channels. These digital inputs have pre-assigned
process supervision functionality as described in
Table 5:

The voltage level of the high potential (channel is
values (24V, 48V, 110V, 125V, 220V DC). The voltage level of the low potential (channel is
0V.
The voltage level can be set as a configuration parameter on SAM600 system level and on the
individual SAM600 modules
Tool.
The high potential is detected after exceeding 80% of the selected voltage level. The low
potential is detected after falling below 20% of the selected voltage level.
Configuration parameters
failure activation level (SAM600-VT only) can configure the polarity for the fuse failure and the
test switch indication inputs. Besides the selection of the polarity (active on high potential,
active on low potential) with which test switch and fuse failure are detected as active, the
input detection can also be disabled by selecting the parameter value
case, the SAM600 module does not report any indication irrespective of the potential detected
on its digital inputs.
The polarity can be configured on SAM600 system level and on the individual SAM600 modules
in the PCM600 Parameter Setting Tool.
If the digital inputs are not disabled, then their status can influence the quality information of
the related samples in the IEC/UCA 61850-9-2LE stream (see
2.3.8

Configuration of time synchronization

Time synchronization options
The time synchronization methods of a SAM600 system are:
• Synchronization by IEEE 1588 (IEC 61850-9-3 profile)
• Free-running
• Synchronization by 1PPS
The sample synchronization field (SmpSync) of the generated SV streams depends on the
configured synchronization method and the current state of the system.
