CR9000X & CR9000XC Specications

Electrical specications are valid over a -25° to +50°C range unless otherwise specied; extended testing over -40° to +70°C range available as an option, excluding batteries.

Non-condensing environment is required. To maintain specications, Campbell Scientic recommends recalibrating dataloggers every two years.We recommend that you

conrm system conguration and critical specications with Campbell Scientic before purchase.

CR9032 CPU MODULE

MINIMUM SCAN TIME PER MODULE (for VoltDiff or TCDiff):

1460 µs with no input reversal and no open circuit detection;

selecting input reversal (Rev parameter = 1) adds 2300 µs to the

minimum scan time and selecting open circuit detection

(voltage range = V2C) adds 1460 µs to the minimum scan time.

If the scan time is insufficient, the CR9000X will report an error at

compile time.

71.58 minutes before it rolls over. The maximum

CR9000X scan rate is 1 minute.

Thresholds: Pulse counted on transition from below 1.5 V

to above 3.5 V

Note: Because of the pulse channels' input filter with a

200 ns time constant, higher frequencies will require

larger input transitions.

TRANSIENT PROTECTION

All analog and digital inputs and outputs use gas discharge

tubes and transient filters to protect against high-voltage tran-

sients. Digital I/Os also have over- voltage protection clamping.
