IC695ALG600 | General Electric | Input Module

Manufacturer

GE Fanuc

Series

Versamax

Part Number

IC695ALG600

Product Type

Thermocouple Input Module

Number of Channels

8

Input Resolution

11 to 16 bits

Power Dissipation

5.4 Watts

Backplane Power Requirement

400 mA at 5V, 350 mA at 3.3V

RTD Cable Impedance

25 Ohms

RTD Wire Length

1000 feet

Open circuit detection time

5 seconds max. Open circuit detection is available for all configurations except +/- 20mA current, 0-20mA current, and +/-10V voltage.

Max Overvoltage

+/-14.5VDC continuous

Max Overcurrent

28 mA continuous

Normal Mode Noise Rejection

95 dB minimum @ 50/60 Hz with 8 Hz filter

85 dB minimum @ 50/60 Hz with 12 Hz filter

Common Mode Noise Rejection

120dB minimum @ 50/60 Hz with 8 Hz filter

110dB minimum @ 50/60 Hz with 12 Hz filter

Settling time to 5% of Full Scale (notch filter dependent)

<80 mS

Calibrated Accuracy at 25°C

Better than 0.1% of range (except 10 ohm CU RTD)

Accuracy depends on A/D filter, data format, input noise, and ambient temperature.

Calibration interval

12 months typical to meet accuracy specifications over time. Module will allow for user offset to be applied as a periodic calibration adjustment.

Input Offset Drift with Temperature

3.0 milliohm/°C maximum

2.0 uV/°C maximum

Gain Drift with Temperature

50 ppm/°C typical (90 ppm/°C maximum)

Module error over Full Temp range

0.5% of range typical (depends on range)

1.0% of range maximum

Module Scan Time (notch filter dependent)

(Assumes 2 ADC’s running in parallel, no CJC or lead resistance) 10 ms per Channel × 4 Channels = 40 ms  (1K Hz filter)

127 ms per Channel × 4 Channels = 508 ms (8 Hz filter)

Channels that are disabled are not scanned, shortening scan time.

Module conversion method

Sigma-delta
