cations
Parameter Description
Absolute Maximum Common
Mode Voltage
Measured between output terminals and controller common:
1,000V
Resolution
15 bits (plus polarity bit for voltage outputs)
(0.305mV for 10V output range)
(0.00061 mA for 20 mA output range)
Accuracy (Calibrated for Voltage
Output)
For voltage output: ± 0.005V (0.05% at full scale)
For current output: ± 0.1 mA (0.5% at full scale)
Temperature coefficien 440 ppm/ °C typical
Isolation Breakdown Voltage 1,000V between input power and signals
Current 0 to 20 mA (500 Ω load max.)
Voltage 0 to 10V Î (dc) with 10 mA source capability
Output Response Time 1 ms typical
Update Rate
Once per controller A/D cycle nominal. Twice per second max-
imum for 60 Hz clock rate.
Output changes are step changes due to the fast time con-
stant. All Serial DAC loop outputs are updated at the same
time.
