Model 10AAO-8 Analog Output Card     [Back ]

This card provides up to eight independent, digitally-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 controlled 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 ("e"), through a command of

ANO x = e

For conversion of one or more 10AAO-8 outputs to standard 4-20 mA signals or to ±10 VDC, see the Model 10CAI-8 (below); for generation of isolated ±10 VDC outputs, see the Model 10CISO-8 (below).

* Higher filter values (1 kHz, 2 kHz, or higher) are available on specially modified versions of the 10AAO-8 (contact the factory for details).

Model 10AAO-4 Analog Buffer Card     [Back ]

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 individual System 10 analog signals.  Each signal may originate from any system Conditioner Card that provides "AUXILIARY OUTPUT" to wire-wrap pins on the mainframe's Analog Motherboard.*  The actual gain setting for each output will depend on the "TYPE" code of the corresponding "source" conditioner channel.

Each of the 10AAO-4's four outputs is nominal ±5 VDC (±6 V maximum), with a minimum load resistance of 2 kΩ.  Each output is factory-set for a "single-ended" configuration—i.e., output referenced to Signal Common (Ground).  If desired, however, all four outputs may be reconfigured as "floating," by connecting an external supply of ±9 VDC, 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 calibration or scaling of a given channel with reference to its "source" input.

For conversion of one or more 10AAO-4 outputs to standard 4-20 mA signals or to ±10 VDC, see the Model 10CAI-8 (below); for generation of isolated ±10 VDC outputs, see the Model 10CISO-8 (below).

* The following cards do not produce "Auxiliary Output" and may therefore not be directly connected to the Model 10AAO-4 without special modification: 10A9-8C, 10A10-4, 10A15-8, 10A35, 10A62-8, 10A64-8C, 10A65-8, and 10A69-4.

Model 10CISO-8 Isolated Analog Buffer Interface [Back ]

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 minimum load resistance of 2.5 kΩ). Common-mode range for the 10CISO-8 is ±50 V, with a rejection ratio of -46 dB at DC and at 60 Hz.

The 10CISO-8 may be used to amplify the standard ±5-V analog outputs of a Model 10AAO-8 or Model 10AAO-4, or of a Conditioner Card that issues such output.  A six-foot power cord comes with every unit, with a switch-selectable transformer that may be plugged into any standard source of 110 or 220 VAC.  Model 10CISO-8 dimensions (HWD in inches/cm) are 1.14/2.90, 9.05/22.99, 3.25/8.26.

Model 10CAI-8 Buffer Interface [Back ]

Using this externally mounted buffer unit with the Model 10AAO-8 or Model 10AAO-4, you can directly connect system analog outputs to a test or process that employs ISA standard 4-20 mA control signals, or you can amplify analog outputs to the ±10 VDC range.

Receiving up to eight standard ±5-V inputs from the 10AAO-8 or 10AAO-4, 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-8 or 10AAO-4 output of 0 to +5 VDC)
	4 to 12 to 20 mA ("zero-center," corresponding to a -5 to +5 VDC output)
	±10 VDC (corresponding to a -5 to +5 VDC output)

All 10CAI-8 outputs are "single-ended," and return to Signal Common.

A six-foot power cord comes with every unit, with a switch-selectable transformer that may be plugged into any standard source of 110 or 220 VAC.  Model 10CAI-8 dimensions (HWD in inches/cm) are 1.14/2.90, 9.05/22.99, 3.25/8.26.
