4.1 Configuration
The SCM-TLC system has two main types of operation, within which there may be
various versions, depending on the number of data acquisition cards fitted: automatic
change over (1+1 or N+1) and telemetry, or just telemetry.
4.1.1 Automatic change over and telemetry
Two types of devices control this type of operation:
SCM 1+1-LCD: automatic change over between the main transmitter and a stand-
•
by transmitter; supports up to 3 additional telemetry cards for a total of 30 balanced
analog inputs, 58 digital/analog inputs and 24 relay outputs.
SCM 4+1-LCD: automatic change over among several main transmitters (up to
•
4) and a stand-by transmitter, automatically configured to substitute the transmitter
affected by the fault (the stand-by must have an external control for setting the
operating frequency); supports up to 2 additional telemetry cards, for a total of 27
balanced analog inputs, 52 unbalanced digital/analog inputs and 16 relay outputs.
4.1.2 Telemetry
Two devices are available for station telemetry, depending on complexity and the
number of parameters to be acquired:
TLC300: includes 2 telemetry cards, for a total of 16 balanced analog inputs, 32
•
digital/analog inputs and 16 relay outputs.
TLC2000: supports up to 6 additional telemetry cards, for a total of 48 balanced
•
analog inputs, 96 unbalanced digital/analog inputs and 48 relay outputs.
The table below summarizes all possible SCM-TLC system configurations.
