Arbin Instruments provides a wide
variety of auxiliary modules for expanding the
capability of the main
I, V
control circuitry. These auxiliary modules are
classified as input-only, input/output, and control
modules. Each module is of plug-in type to the bus
board, which carries all communications and power
distribution.
Input Modules
Auxiliary inputs can be used to record
corresponding data and control tests based on measured values. We offer auxiliary voltage, temperature (thermocouple and thermistor), pressure, and pH modules. Each module contains 8 channels (except thermistor which contains 16). Modules can be added in multiples.
Input/Output Modules
The Digital Input/Output module sends and receives a simple digital
on/off signal. Available in TTL and Relay. 8ch input and 8ch output
per module. We also offer Analog I/O channels. Please contact us for Analog requests.
Control Modules
Arbin also offers control modules for
auto-calibration, AC impedance, Smart Battery (SMBus), External Charger, High Speed Pulse, Temperature Chamber Interface, etc. For other special requests (CAN Bus) please contact us for availability.

High Speed Pulse
TThis option provides the capability to run GSM, CDMA, TDMA or
other custom designed pulses. We define a High Speed Pulse as a subsecond
single or repeated pulse profile. Each single pulse profile can
have up to 10 stages. To generate a good pulse shape, it is important
to have a rise time that matches your pulse requirement. Pease consult with your Sales Engineer regarding the appropriate circuit to meet your
requirements.

Smart Battery Testing
The smart battery (SMB) auxiliary module is used to communicate with smart batteries using SMBUS 1.1 or 2.0 (please specify). This feature allows the user to read/write registers on teh smart battery as well as compare data collected from the smart battery with data that the Arbin system measures directly. Both the behavior of electronic devices residing in
the smart battery and the performance of the smart
battery itself can be tested with this function.

External Charger/Load
This is a useful option when qualifying chargers to be used with your
batteries or studying load profiles. Using this option, the user connects
the battery to the regular channel and the charger or load to the External
Charge input provided. The user can program the battery to be
charged/discharged by the external charger/load at a predetermined step
in the schedule. The system internally and automatically connects the
battery to the charger/load. During the External Charge/Load step, the
Arbin system collects data about the charger/load performance. The
system then disconnects the charger/load once the preset limit
conditions are met.

Auto-Calibration
This option allows all the channels to be calibrated automatically for
each current range (current <=20A), each voltage range
(voltage<=70V), and each auxiliary voltage channel. The user sets the
desired accuracy and this module will generate a results report once the
calibration has finished. This report documents the “as found” and “as
left” calibration information. An HP34401A, HP34410A, or
KEITHLEY2100 multimeter is generally used in this process (sold
separately). This option includes the ACVIVUS-8 connection bus and
necessary wiring for up to 24 channels. Additional ACVIBUS-8
modules can be purchased separately.

AC Impedance Measurement
AC impedance measurement is recommended to
obtain a samples internal impedance. This measurement is commonly used to determine the health of a battery, capacitor, or fuel cell. While the Arbin system is not designed to replace dedicated FRA or scanning AC Impedance equipment, it
can provide a general idea about the impedance of the device under test - and at a fraction the cost of specialized FRA equipment. The ACIM module can achieve an accuracy of ±5% of the measured value.
This module applies sine wave current at
four fixed frequencies (200Hz, 500Hz, 1kHz, or 2kHz) to the device and the resulting values can be used to control the test.

Temperature Chamber Interface
The Temperature Chamber Interface option (MTCI) allows the system
to communicate with a temperature chamber controller during testing.
The MTCI module tells the chamber controller what temperature setpoint
to use during each test step, allowing the user to program
complex automatic temperature profiles in their tests. Consult your
Sales Engineer for a full list of supported chambers and MTCI
specifications.
