Designed for RTD-based temperature measurements requiring high input isolation, this precision conditioner is particularly useful in the utilities industry. It is identical to the Model 10A16-4C, except that
- it accepts two independent platinum RTD signals (rather than four), and may only be used in System 10
- its inputs are transformer-isolated, so that sensor-to-chassis and/or sensor-to-sensor common-mode voltages as high as 1500 V-DC can be accommodated without damaging the instrument or perceptibly affecting measurement accuracy
Specifications:
- RTD Types: Platinum; DIN (European) standard with "ice-point" resistance of 50, 100, or 200 ohm, or American standard with "ice-point" resistance of 100 ohm
- Range and Resolution: See Table below; automatically selected- on an individual channel basis- when the channel is configured
- Linearization: Internal digital linearization; maximum error: ±0.1° C (±0.2° F)
- Excitation (per channel): Nominal 5 V-DC; 1 mA, maximum
- Amplifier (per channel):
Common-Mode Range: ±1500 V operating and without instrument damage
Common-Mode Rejection Ratio: DC: -150 dB; at 60 Hz: -160 dB; at 1 kHz and 3 kHz: infinite
Leadwire Resistance Rejection (4-wire only): 0.004% per ohm
Offset: Initial: ±0.01% of full scale; vs. Temperature: ±10 ppm/°C; vs. Time: ±10 ppm/month
Gain Accuracy: ±0.02% of full scale
Gain Stability: vs. Temperature: ±50 ppm/°C; vs. Time: ±50 ppm/month
- Filter (per channel): 3-pole modified Butterworth; 3 dB down at 2 Hz; 60 dB down at 30 Hz
Step-Response Settling Time (Full-Scale Output):
To 1% of final value: 260 msec
To 0.1% of final value: 500 msec
To 0.02% of final value: 600 msec
- Total System Accuracy (typical, including Model 10A17-2 and system data collection and processing): see Table below
- Auxiliary Outputs: Filtered outputs available on wire-wrap pins
