This conditioner is similar to the Model 10A61-2, except that it accepts up to eight independent 4-20 mA input signals and offers substantially higher internal accuracy (see Specifications). Although it has a lower common-mode operating range than the 10A61-2, it has a greater common-mode input impedance. Unlike the 10A61-2, it has no auxiliary outputs from wire-wrap pins. It may be used in either System 10 or the SPS8000 System.Specifications:
- Input Current: 4 to 20 mA (unipolar) or 4 to 12 to 20 mA (bipolar or "zero-center"); automatically selected- on an individual channel basis- when the channel is configured
- Amplifier (per channel):
-
Common-Mode Range: ±20 V operating; ±50 V without instrument damage
Common-Mode Rejection Ratio: DC: -100 dB; at 60 Hz, 1 kHz, and 3kHz: -150 dB
Input Impedance: Differential: 100 ohm; Common-Mode: 500 k-ohm
Burden: 2 V-DC at full scale
Offset: Initial: ±0.02% of full scale; vs. Temperature: ±20 ppm/°C; vs. Time: ±20 ppm/month
Gain Accuracy: ±0.02% of full scale
Gain Stability: vs. Temperature: ±50 ppm/°C; vs. Time: ±20 ppm/month
- Filter (per channel): 3-pole modified Butterworth; 3 dB down at 5 Hz; 60 dB down at 100 Hz
-
Step-Response Settling Time (Full-Scale Output):
To 1% of final value: 170 msec
To 0.1% of final value: 240 msec
To 0.02% of final value: 270 msec
