Description
The HP 12060B and HP 12061A are plug-in cards for HP 1000
A-Series computers for low-cost, high-performance analog input
capability in small distributed measurement and control applications.
The A-Series product in which these cards are used must have a 25 kHz
power supply. The HP 12060B High-Level Analog Input Card provides the
capability of converting 8 differential analog voltage inputs to digital
form. The HP 12061A Expansion Multiplexer Card provides an additional 32
channels of differential input for a total capability of 40 channels.
All inputs are protected against accidental over voltage to 42 V peak.
HP 12060B Card
The HP 12060B is capable of acquiring up to 55,000 readings per
second with 12-bit resolution. Auto scanning or single-channel sampling
is possible to 55 kHz. Provisions for external pacing/triggering of
sampling and scanning is provided. The HP 12060B includes four
programmable full-scale ranges from +/-1.28 V to +/-10.24 V. Maximum
resolution is 0.625 mV on the 1.28 V range to 5 mV on the 10.24 V range.
A separate "zero reference" on the card allows the user to measure
actual offset due to temperature drift, and correct reading on all 40
channels for higher accuracy.
HP 12061A Card
The HP 12061A provides 32 additional differential inputs for the
HP 12060B card. It fastens directly onto the HP 12060B card, creating a
two-board unit that occupies two I/O slots in an HP 1000
A-Series computer. Programming information is passed from the HP 12060B
directly to the HP 12061A; analog signals on the additional 32 channels
are in turn passed back to the HP 12060B for digitizing. The HP 12061A
includes removable plug-in headers so the user can add current sense
resistors for current loop measurements. These headers allow the board
to be adapted to the specific application without soldering components
HP 12060BC and 12061AC Cables
The HP 12060BC 8-channel Analog Input Cable and the HP 12061AC
32-channel Analog Input Cable provide for easy connection of your
application to the HP 12060B and HP 12061A respectively. Both products
provide a 3-meter cable prewired to the appropriate card-compatible
edge-connector/hood assembly. Each channel is an individually shielded
twisted pair for optional analog performance. The "remote" end of the
cable is unterminated allowing direct wiring to the application.
Alternately, the cable may be wired to the easy-to-use insulation
displacement HP 12064A Termination Accessory providing
electrician-compatible heavy-duty screw terminals and built-in wiring
tray (see HP 12064A data sheet).
User Programming
User programming of both cards is easily accomplished using the parallel
interface I/O driver (ID.50) in the RTE-A Operating System. A simple RTE
EXEC call is all that is needed for full control of both cards. The
format is as follows:
CALL EXEC (1, LU#, Data Buffer, # readings, control word)
The control word specifies:
o Gain (1, 2, 4, or 8)
o Start Channel: Scanning always begins at the specified "Start
Channel" on the highest channel available (8 for the HP 12060B only
and 40 with the HP 12061A). If more than one scan worth of readings
has been requested, the next scan and all subsequent scans will also
begin at the "Start Channel."
o Auto Scan: The user specifies the starting channel(1-40) and the
number of readings to be taken. The card will automatically begin at
the starting channel, increment to the next and so forth, returning to
the starting channel when reaching channel 8 (HP 12060B only) or
channel 40 (HP 12061A), continuing until the specified number of
readings have been taken.
o Single Channel: The user specifies the number of readings on a
specific channel. The card then takes the readings requested.
o Internal Pacing: The card begins taking readings on commands and
takes all readings at the maximum rate (18 ohms per reading), either
scanning or on channel.
o External Pacing: The card begins taking readings when the external
pace input goes high and stops when it goes low. This allows for
pacing on channel by supplying a pace pulse less than a conversion
time wide (nominally 15 ohms) for a specified number of readings. In
auto scan mode, it allows pacing the start of scan by holding the
input high for "n" readings per scan times one conversion time.
Alternatively, readings in auto scan mode may be taken at any rate by
applying a pulse train with a pulse width <15 ohms.
With a single call you can cause multiple scans and/or set up and
wait for an external trigger.
Note: See related products information concerning MAC/1000
high-level call subroutines for A-Series M&C interfaces.
Calibration
The HP 12060B is calibrated at the factory and may require
recalibration by the customer on arrival by using a voltage source and
optional calibration software.
