IntelliPack Series 811T Transmitter/Alarm User's Manual DC Voltage/Current Input
__________________________________________________________________________________________
- 4 -
Alarm Relay Model Only (811T-1500)
•
Powerful Alarm Functionality
- May be programmed for
limit alarms with deadband, latching/non-latching contacts,
and failsafe/non-failsafe operation.
•
High-Power SPDT Relay Contacts -
Includes a Single-
Pole-Double-Throw (SPDT) electro-mechanical alarm relay
for switching up to 230VAC and 5A.
•
Failsafe or Non-Failsafe Relay Operation
- May be
configured for failsafe or non-failsafe relay operation. Upon
power up, relay may cycle states during diagnostic
operation.
•
Configurable Setpoint With Deadband
- Deadband helps
to eliminate relay “chatter” and prolong contact life.
•
Programmable Latching or Momentary Alarms
- May be
configured for automatic alarm reset, or a latching alarm
with manual push-button or software reset.
•
Programmable Relay Time Delay Filters Transients
-
Useful for increased noise immunity and to filter transients.
ACCESSORY ITEMS
The following IntelliPack accessories are available from
Acromag. Acromag also offers other standard and custom
transmitter and alarm types to serve a wide range of applications
(please consult the factory).
IntelliPack Configuration Software (Model 5030-881)
IntelliPack alarms and transmitters are configured with this
user-friendly Windows 95
or NT
Configuration Program. This
software package includes the IntelliPack Alarm Configuration
Manual (8500-563) and IntelliPack Transmitter Configuration
Manual (8500-570). These manuals describe software operation
and various alarm and transmitter functions in detail. The
Configuration Software also includes an on-line help function.
All transmitter and alarm functions are programmable and
downloadable to the modules via this software. Non-volatile
memory provides program, configuration, and data storage within
the IntelliPack.
IntelliPack Serial Port Adapter (Model 5030-913)
This adapter serves as an isolated interface converter
between the EIA232 serial port of the host computer and the
Serial Peripheral Interface (SPI) port of the IntelliPack module. It
is used in conjunction with the Acromag IntelliPack Configuration
Software to program and configure the modules. This adapter
requires no user adjustment, no external power, and operates
transparent to the user. It receives its power from the IntelliPack
module. The adapter has a DB9S connector that mates to the
common DB9P serial port connector of a host computer. The
adapter also has a 6-wire
RJ11 phone jack to connect to the
IntelliPack alarm module via a separate interconnecting cable
(described below). Refer to Drawing 4501-635 for computer to
IntelliPack connection details.
IntelliPack Cable (Model 5030-902)
This 6-wire cable is used to connect the SPI port of the
IntelliPack Serial Port Adapter to the IntelliPack. This cable
carries the SPI data and clock signals, reset signal, and +5V
power and ground signals. The cable is 7 feet long and has a 6-
wire RJ11 plug at both ends which snap into jacks on the Serial
Port Adapter and the IntelliPack module.
IntelliPack Software Interface Package (Model 800C-SIP)
The IntelliPack Software Interface Package combines the
Configuration Software (5030-881), Alarm Configuration Manual
(8500-563), Transmitter Configuration Manual (8500-570), Serial
Port Adapter (5030-913), and Cable (5030-902), into a complete
kit for interfacing with IntelliPack Alarms and Transmitters.
AC Current Sensor (Model 5020-350)
This optional sensor is an accurate toroidal instrument
transformer used to convert a sinusoidal 50-60Hz AC current
signal into a low level DC milliampere signal of 0 to 11.17mA.
The input AC current range is a simple function of the number of
turns placed through the toroid as shown in Table 2. This sensor
is isolated and requires no calibration or adjustment. A sensor
used with the IntelliPack provides redundant input isolation.

The output wires of this sensor are polarized: Red is (+) plus
and Black is (-) minus. Normally these output wires are attached
to one end of a user supplied cable, and the other end of the
cable connects to the IntelliPack Transmitter’s process current
input terminals.
Input Burden
: Is a function of the wire gauge resistance
used for the primary turns (the current carrying wire being
monitored).
Input Overload
: The AC current sensor will withstand
overload conditions as follows:
•
20 times full scale for 0.01 seconds.
•
10 times full scale for 0.1 seconds.
•
5 times full scale for 1.0 second.
AC Current Sensor to Transmitter Wiring Distance
: 400
feet maximum for 18 gauge wire. Other wire gauges can be
used as long as the resistance of both wires is less than 5
.
