The AOM Analog Output
Module
The Analog Output Module (AOM) accepts
information from the NCS and outputs it as one of four
independently configurable analog signals.

Output Ranges:
Programmable for any range
within: Current (sink or
source), 0-20mA or Voltage,
0-10V
Accuracy: ±0.015% of
maximum span
Output Resolution: 18-bit
Stability (% of max. span):
Current:
1-year, 0.012%;
3-year, 0.020%;
5-year, 0.026%
Voltage:
1-year, 0.066%;
3-year, 0.11%;
5-year, 0.15%
Isolation:
500Vrms,
continuous, from channel to
channel, from each channel
to case, and from each
channel to terminals of other
attached NCS modules; will
withstand 1000Vrms dielectric
strength test for one minute,
with no breakdown, from each
channel to case, and from
each channel to terminals of
other attached NCS modules
Scan Time: The time
required for the Interface
Module to access process
variable and status data from
all four channels of the AOM
is 16ms
Response Time:
50ms to 90% of final value
on a step input
Output Damping:
Increases response
time by adjusting filter
time constant from 0-30
seconds
Ripple:
Current, 10mV
peak-to-peak measured
across a 250ohm load
resistor; Voltage, 50mV
peak-to-peak maximum
Load Capability:
Current, 0-1000ohms
(source), 42V maximum
(sink) 1500ohms; Voltage,
0-5mA (2000 ohms
minimum load)
Output Limiting:
Current
output is guaranteed
up to 21.6mA (or 10%
of full scale above the
programmed full value)
and limits at 23.6mA;
Voltage output accuracy
is guaranteed up to 10.5V
(or 5% of full scale above
the programmed full
value) and limits at 11.0V
Load Effect (current
outputs): 0.01% of span
from 0 to maximum load
resistance on current
output
Output Failure Mode:
Outputs are programmable to
either hold last value or go to
a pre-defined value on error
upon lost communication
with the Interface Module or
upon receiving invalid primary
variable data
Power Supply:
Power is supplied by the
Interface Module,
4W maximum
Diagnostic Information:
Refer to Appendix B Table 8
One red/green LED per
channel indicates proper
channel operation (green) or
that the channel is in a fault
condition (red)
Operating Range:
–40°C to +85°C
(–40°F to +185°F)
Storage Range:
–40°C to +85°C
(–40°F to +185°F)
Ambient Temperature
Effect: 0.01% of maximum
span/°C
Relative Humidity:
0-95%, non-condensing
RFI/EMI Protection:
20V/m@20-1000MHz, 1kHz
AM when tested according to
ENC61000-4-3-1996
