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

or computer instructions.

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 KΩ). 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 aΩ

“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.

52A 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 CatalogNone 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.
