IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures
in designing any type of control or monitoring system. This is
especially important where economic property loss or human life
is involved. It is important that the user employ satisfactory
overall system design. It is agreed between the Buyer and
Acromag, that this is the Buyer's responsibility.

DESCRIPTION
Series 89XM Computation Transmitters are members of the
popular Acromag IntelliPack Transmitter & Alarm family. These
models will accept two or four channels of DC current or voltage
input, and provide an isolated process current or voltage output
whose response is computed via a programmed mathematical
combination of the input signals. Units are fully reconfigurable via
our user-friendly Windows 95/98
or NT
IntelliPack
Configuration Program. All IntelliPacks contain an advanced
technology microcontroller with integrated downloadable flash
memory for non-volatile program, configuration, calibration, and
parameter data storage. Once configured, these modules may
operate independent of the host computer for true embedded
computation monitoring and control.
Modules may be field connected for either process current or
DC voltage input or output signals. The 892M has two current or
voltage inputs which may be mathematically combined to drive an
isolated process current or voltage output, while the 894M
provides up to four current or voltage inputs. A wide variety of
math operators and functions are supported. On-board excitation
is provided at the inputs to facilitate two-wire, 4 to 20mA process
current transmitter hookup. Each channel includes a yellow LED
on the front-panel to provide visual indication of an over-range
input signal. Additionally, a green “Run” LED indicates power and
operation status.
The module uses a high resolution, low noise, Sigma-Delta,
Analog to Digital Converter (
-
ADC) to accurately convert the
input signals into digitized values. An optically isolated Digital-to-
Analog Converter (DAC) provides the corresponding process
current or voltage output. All scaling and computation is
performed using single-precision, floating point arithmetic.
