Model 10AAO-8
Analog Output Card
This card provides up to eight independent, digital-
ly-controlled analog output signals that can be
used for commanding servo control loops, and for
driving external recorders, plotters, indicators, etc.
The eight voltage outputs are individually con-
trolled and updated once each scan cycle by the
system Central Processor, in accordance with user
The data source for each 10AAO-8 output may be
specified as a linear function of any system data
channel No. y by applying an ANALOG OUTPUT
(ANO) command of
ANO x = m(CHN y) + b
where “m” and “b” are floating-point constants
entered by the user to convert the engineering units
of Channel No. y to millivolts. The allowable
range is ± 5000 mV. Alternatively, the data source
for an analog output may be specified as a fixed
millivolt value.
Additional 10AAO-8 Specifications:
Voltage Signal Output:
Configuration: Single-ended, return to
System Common
Range: ±5 volts, with 20% overrange
Resolution: Settable to one millivolt
Allowable Loading: 5 mA, maximum
Accuracy: ±0.05%, ±1 millivolt
Response Time: Output updated once
each scan cycle, and processed through
3-pole, 4-Hz active filter (settling time 300
milliseconds)**; scan cycles per second =
2500/(N + 15), where N is total number
of channels
Model 10CISO-8 Isolated
Analog Buffer Interface
The Model 10CISO-8 is an external unit for ±10-V
isolated buffering of up to eight individual analog
signals (with 20% overrange at 1 mA and mini-
mum load resistance of 2.5 K). It may be used
to amplify the standard ±5-V analog outputs of a
Model 10AAO-4 Model 10AAO-8or , or of a
Conditioner Card that issues such output. A six-
foot power cord comes with every unit, with a
Offset: Initial: ±1 mV; vs. Temp.: ±0.25
mV/°C; vs. Time: ±1 mV/month
Gain Accuracy: ±0.02% of full scale
Gain Stability: vs. Temp.: ±50 ppm/°C;
vs. Time: ±10 ppm/month
Filter: 3-pole modified Butterworth; 3 dB down
at 200 Hz; 60 dB down at 3.4 kHz
Step Response Settling Time
(Full-Scale Output):
To 1% of final value: 5 msec
To 0.1% of final value: 7 msec
To 0.02% of final value: 10 msec
Analog Memory Decay Rate: Does not
exceed 1 mV/sec
Analog Outputs (per input channel):
“+ PEAK” and “– PEAK” available at rear
connector; there is no direct “MAX-MIN”
analog output. The full-scale amplitude of
any given output will be a function of the
“TYPE” designation of the respective analog
input channel.
Model 10AAO-4
Analog Buffer Card
For purposes of “real-time” monitoring, the Model
10AAO-4 provides continuous buffering, filtering,
and fixed gain of 1, 2, or 4 for up to four individ-
ual System 10 analog signals. Each signal may
originate from any one of the system's Conditioner
Cards that provides “Auxiliary Output” to wire-
wrap pins.* The actual gain setting for each out-
put will depend on the “TYPE” designation of the
corresponding “source” conditioner channel.
Each of the 10AAO-4's four outputs is nominal ±5
V-DC (±6 V maximum), with a minimum load
resistance of 2 k . Each output is factory-set for a
“single-ended” configuration (i.e., output refer-
enced to Signal Common (Ground)). If desired,
however, all four outputs may be reconfigured as
“floating,” by connecting an external supply of ±9
V-DC, furnished by the user.
Each 10AAO-4 channel contains a 3-pole modified
Butterworth filter with a bandwidth of 47 Hz. In
addition, individual ZERO and SPAN controls are
accessible at the front of the card, for further cali-
bration or scaling of a given channel with refer-
ence to its “source” input.
52 A Cards
Special Function A Cards & Accessories
* Cards “Auxiliary Output” currently include the Models 10A9-8C, 10A10-4, 10A15-8, 10A35,without
10A62-8C, 10A64-8C, 10A65-8, and 10A69-4 (see the latest Conditioner Card Catalog None of).
these cards may be directly connected to the Model 10AAO-4 without special modification.
** Higher filter values (1 kHz, 2kHz, or higher) are available on specially modified versions of the
10AAO-8.
Model 10CISO-8 (HWD in inches/cm:
1.14/2.90; 9.05/22.99; 3.25/8.26)
Model 10CAI-8 (HWD in inches/cm:
1.14/2.90; 9.05/22.99; 3.25/8.26)
switch-selectable transformer that may be plugged
into any standard source of 110 or 220 AC.
Common-mode range for the 10CISO-8 is ±50 V,
with a rejection ratio of -46 dB at DC and 60 Hz.
Model 10CAI-8 Eight-
Channel Buffer Interface
Using this externally mounted buffer unit with the
Model 10AAO-4 Model 10AAO-8or , you can
directly connect system analog outputs to a test or
process that employs ISA standard 4-to-20 mA con-
trol signals, or you can amplify analog outputs to
the ±10 V-DC range.
Receiving up to eight standard ±5-V inputs from
the 10AAO-4 or 10AAO-8, the 10CAI-8 produces up
to eight corresponding output signals, each of
which is individually programmable for full-scale
representation as
4 to 20 mA (corresponding to a 10AAO-4 or
10AAO-8 output of 0 to +5 V-DC);
4 to 12 to 20 mA (“zero-center,” corresponding
to a -5 to +5 V-DC output); or
±10 V-DC (corresponding to a -5 to +5 V-DC
output).
All 10CAI-8 outputs are “single-ended,” and return
to Signal Common.
A six-foot power cord comes with every 10CAI-8,
with a switch-selectable transformer that may be
plugged into any standard source of 110 or 220
V-AC.
