Supply Voltage (nominal)
+5 VDC and +12 VDC backplane
Update Rate
250 ms (all channels) Determined by I/O scan time and is application
dependent
Resolution
12 bit (no sign bit)
Accuracy
+ 0.2% @ 25 °C. + 0.5% @ -20 to 70 °C

Isolation
Analog outputs 1 & 2 and analog outputs 3 & 4 form two groups.
Each group is isolated from the other group and from the backplane
logic. There is no isolation between outputs 1 & 2 and no isolation
between outputs 3 & 4.
•
Transient voltage (Group to Group and Group to Logic): 1.5 kV
Operating Temperature
-20 to 70 °C
Storage Temperature
-40 to 85 °C
Operating Humidity
5 to 98% RH non-condensing
Hot Swap
Yes. Module can be swapped while RTU is running. Hot swap will not
cause a Warm Start. Outputs will be restored within 2 seconds once
module is replaced.
Open Loop Detection
Not supported. Please see AO-3.
