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.
1.0 INTRODUCTION
These instructions cover hardware functionality of the
transmitter models listed in Table 1. Supplementary sheets are

Notes (Table 1):
1. Agency approvals include cULus Listed.
2. Include t
he “-C” suffix to specify factory configuration option.
Otherwise, no suffix is required for standard configuration.
3. Model 811T-0500 units have transmitter functionality only,
while 811T-1500 transmitters include an alarm relay.
Module programming, transmitter operation, and the
IntelliPack Configuration Software is covered in the IntelliPack
Transmitter Configuration Manual (8500-570).
DESCRIPTION
Series 811T Transmitters and combination Transmitter/
Alarms are members of the popular Acromag IntelliPack
Transmitter & Alarm family. These models will accept DC current
input, DC voltage input, and AC current input (using an external
sensor). The transmitter output is an isolated process current or
voltage, plus an optional Single-Pole Double-Throw (SPDT)
electro-
mechanical alarm relay (“-1500” units). All IntelliPacks
contain an advanced technology microcontroller with integrated
downloadable flash memory and EEPROM for non-volatile
program, configuration, calibration, and parameter data storage.
Units are fully reconfigurable via our user-friendly Windows 95
or NT
IntelliPack Configuration Program. Field reconfigurability
is also possible with module push-
buttons and status LED’s.
Once configured, these modules may operate independent of the
host computer for true embedded monitoring and control.
Modules may be field connected for either process current or
DC voltage input or output signals. The 811T has a single
current or voltage input, an isolated process current or voltage
output, and an isolat
ed SPDT alarm relay (“-1500” units). On-
board excitation is provided at the input to facilitate a two-wire, 4
to 20mA process current transmitter hookup. Wide range bipolar
DC voltage inputs to
100VDC are possible. The relay has a
yellow LED on the front of the module that provides a visual
indication of the high or low alarm condition. Additionally, “Run”,
“Status”, and “Zero/Full-Scale” LED’s provide local feedback of
operating mode, system diagnostics, and field configuration
status. Front panel push buttons are available to reset a latched
alarm and to facilitate field configuration without connecting to a
host computer.
