Expansion Board Description
Description 2‐1
Introduction
High Resolution Analog Expansion Board
Catalog No. EXBHH005AXX.
When this board is installed, two high resolution analog inputs are
provided in addition to the two standard analog outputs.
Features:
Two (2) Analog Inputs
Two (2) Analog Outputs
16 Bit Digital Resolution
The Analog I/O expansion board provides two high resolution analog
inputs to the motor control board and two high resolution outputs from
the motor control board. Each input and output may be configured for
0-5VDC, +5VDC, 0-10VDC, +10VDC, 0-20 mA or 4-20mA.
Each analog input and output may be independently configured to a
voltage or current.
Table 2‐1 identifies the characteristics of the High Resolution Analog
Input/Output Expansion Board.
Table 2-2 specifies the signal resolutions for each type of input and
output signal.
Figure 3‐3 and 3‐4 identify the internal configuration and external
connections for the analog input and output signals.
Installation Considerations
Two expansion board slots are available in the control. When this board
is installed, there are a total of four (4) analog inputs and four (4) analog
outputs. The parameters used depend on the slot into which the
expansion board is installed.
If a High Resolution Analog expansion board is:
installed in Slot 1, OP1 ANA IN1 & 2 etc. are active.
installed in Slot 2, OP2 ANA IN1 & 2 etc. are active.
Note: Slot 3 is reserved for a feedback board only.
