3–12 Installation/Wiring for Stand-Alone Drives
All isolated I/O is designed with full galvanic (greater than 10 meg
ohms, less than 50 pf) isolation. This results in an insulation
withstand capability of 200VAC from each channel to PE ground and
between channels. The Analog I/O Option Boards are summarized
below.

Option Board Type Slot Description
LA1 Dual Analog Output B This option replaces both standard analog outputs
withtwo single-endedhighresolutionanalogoutputs.
Analog Output 0 is configurable to 0-10V or 0-20mA
operation while Analog Output 1 is for 0-20 mA oper-
ation only. This option maintains access to the stan-
dard (non-isolated) Analog Input 2 through TB2-6 –
Configuration remains with jumper J11.
LA2 Dual Isolated Input A This option replaces the two standard analog inputs
with two galvanically isolated analog inputs. Both
analog input channels are configurable for 0-10V or
0-20 mA operation.
LA3 Dual Isolated Output B Replaces Analog Input 2 and both standard analog
outputs with two galvanically isolated high resolution
analog outputs. Both analog output channels are
configurable for 0-10V or 0-20 mA operation.
LA4 Isolated Input/
Isolated Output
B This option replaces Analog Input 2 and both stan-
dard analog outputs with a galvanically isolated ana-
log input and a galvanically isolated high resolution
analog output. Both analog channels are config-
urable for 0-10V or 0-20 mA operation.
LA5 Analog Output/Pulse
Output/Pulse Input
B This option replaces Analog Input 2 and both stan-
dard analog outputs with a single-ended high resolu-
tion analog output, a single-ended 5V pulse output,
and galvanically isolated 5V pulse input. The analog
output channel is configurable for 0-10V or 0-20 mA
operation.

Isolated Bipolar/
Isolated Thermistor
Input
A This option replaces the two standard analog inputs
with a galvanically isolated analog input and a gal-
vanically isolated thermistor input. Analog Input 0 is
configurable for ±10V or ±20 mA operation, with
polarity determining forward or reverse operation
Analog Input 1 is suitable for use with PTC sensor
chains with a maximum total resistance at normal
operating temperature of 1.8k ohms. An indication
occursin shortcircuit orover-temperatureconditions.
A short circuit condition is when the total resistance
of the sensor chain is less than 60 ohms
with reset
from the short circuit condition occurring when the
resistance exceeds 70 ohms. An over-temperature
condition is when the total resistance of the sensor
chain exceeds 3.3k ohms
with reset from the over-
temperature conditionoccurring when theresistance
is less than 2.2k ohms.

Isolated Bipolar
Input/Isolated Input
A This option replaces the two standard analog inputs
with two galvanically isolated analog inputs. Analog
Input 0isconfigurable for ±10Vor±20mA operation,
with polarity determining forward or reverse opera-
tion, whileAnalog Input 1is configurablefor 0-10Vor
0-20 mA operation.
