Campbell Scientific GRANITE 9 Specifications
GRANITE 9 Specifications
Electrical specifications are valid over a -40 to +70 °C, noncondensing environment, unless otherwise specified. Extended
electrical specifications (noted as XD in specifications) are valid
over a -55 to +85 °C non-condensing environment.
Recalibration is recommended every three years. Critical
specifications and system configuration should be confirmed
with Campbell Scientific before purchase.

System power out limits (when powered with
12VDC)
Total system current is fused at 5 A with replaceable
automotive mini-blade fuse
12 V and SW12 power output terminals
12V, SW12-1, and SW12-2: Provide 12 VDC power ±10% when
the power input supply voltage is ≥13.7VDC. When the supply
voltage is <13.7V the output voltage will be at least the supply
voltage minus 1.7 volts.
SW12-1 and SW12-2 can be independently set to a regulated
12V under program control.
SW12 current limit: 1100 mA
12 VDC outputs limited to 3300 mA, which is shared by all 12 V
outputs including 12V, SW12-1, SW12-2 and CS I/O pin 8.
5 V fixed output
5V: One regulated 5 V output. Supply is shared between the 5V
terminal and CS I/O pin 1.
l Voltage Output: Regulated 5 V output (±5%)
l Current Limit: 250 mA

Pulse measurement specifications
NOTE:
Conflicts can occur when a control port pair is used for
different instructions (TimerInput(), PulseCount(),
SDI12Recorder(), WaitDigTrig()). For example, if
