West Control Solutions N6600 - Manual (Page 106)

DC
Resolution: Eight bits in 250mS (10 bits in 1 second
typical, >10 bits in >1 second typical).
Accuracy: ± 0.25% (mA at 250 Ω , V at 2 k Ω ). Degrades
linearly to ± 0.5% for increasing load
burden (to limit as stated below).
Update Rate: Every control algorithm execution.
Ranges: 0 - 20mA
4 - 20mA
0 - 5V
0 - 10V
(Changes between V and mA require link jumper movement.)
Load Impedance: 0 - 20mA: 500 Ω maximum
4 - 20mA: 500 Ω maximum
0 - 5V: 500 Ω minimum
0 - 10V: 500 Ω minimum
Isolation: Isolated from all other inputs and outputs.
Range Selection Method: Link jumper.
A.7 LOOP CONTROL
Automatic Tuning Types: Pre-Tune and Self-Tune.
Proportional Bands: 0 (OFF), 0.5% - 999.9% of input span at
0.1% increments.
Reset (Integral Time
Constant):
1s - 99min 59s and OFF
Rate (Derivative Time
Constant):
0 (OFF) - 99 min 59 s.
Manual Reset (Bias): Added each control algorithm execution.
Adjustable in the range 0 - 100% of output
power (single output) or –100% to +100%
of output power (dual output).
Deadband/Overlap: –20% to +20% of Proportional Band 1 +
Proportional Band 2.
ON/OFF Differential: 0.1% to 10.0% of input span.
