2.1.1 Voltage Inputs for Small Level Signal (Strain Gauges, Thermo couple, etc.)
Either two differential voltage inputs to connect up to two full bridges or thermocouples, or to
connect four half-bridge inputs with internal half-bridge completion.
Input ranges:
± 2mV to ± 2V individually adjustable via RCT
(no external resistors or jumpers required)
Resolution:
16 bit
Accuracy:
±0.01% - ±0.025%
Sampling rate:
max. 4.6 kHz sampling rate (excluding additional channels)
Anti-aliasing filter:
6-pole Butterworth with cutoff frequency at 1/5 of the sampling rate
Bridge excitation:
+ 4.096 V (max. 40mA short-circuit proof)
Bridge balance:
> double measurement range, can be adjusted via RCT
Shunt test:
330
kΩ resistor, remote-controlled (as test signal to verify bridge
resistance or for detection of broken thermocouples)
2.1.2 Inputs for high-level signal (voltage measurement)
One differential input and one single-ended input
Input range:
± 0.2V to ± 22.5V individually adjustable via RCT
Resolution:
16 bit
Accuracy:
±0.01%
Sampling rate:
max. 4.6 kHz sampling rate (excluding additional channels)
Anti-aliasing filter:
6-pole Butterworth with cutoff frequency at 1/5 of the sampling rate
