AIIS-1750 Startup Manual 1
Before installation, please ensure that the following items
have been included in your shipment:
• 1 x AIIS-1750 card
• 1 x Quick start user manual
If any of the above items are missing or damaged, contact
your distributor or sales representative immediately.
FCC Class A
This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference
to radio communications. Operation of this equipment in
a residential area is likely to cause interference. In such
cases, users are required to correct the interference at their
own expense.
CE
This product has passed the CE test for environmental
specifications when shielded cables are used for external
wiring. We recommend the use of shielded cables. This type
of cable is available from Advantech. Please contact your
local supplier for ordering information.
The AIIS-1750 offers isolated digital input and output chan-
nels with up to 2,500 VDC isolation protection, making them
ideal for industrial applications that require high-voltage
isolation. Additionally, the AIIS-1750 features a digital filter
on each channel.

Connections
Isolated Digital Input
Each of the 16 isolated digital input channels accepts dry
contacts or 5 ~ 50 VDC voltage inputs. All 16 input channels
share 3 ground pins.
Warning! Be careful when connecting the digital input
cables. Never apply a negative voltage to an
isolated input pin as this may damage the AIIS-
1750 card.
Note for wet contacts: Malfunctions may occur in cases
where the internal resistance of a voltage source under wet
contacts is significant (>5 kΩ). It is advisable to connect a
parallel 5 kΩ, 0.5 Ωresistor to avoid a voltage rise inside
the voltage source. The following figure shows how to con-
nect an external input source to one of the card’s isolated
input channels.
Isolated Digital Output
Each of 16 isolated digital output channels is equipped
with a Darlington transistor. Every 8 output channels share
common collectors and integral suppression diodes for
inductive loads.
Channels 0 ~ 7 use COM0, and channels 8 ~ 15 use COM1
as a common pin.
Note: If external voltage (5 ~ 40 V) is applied to an
isolated output channel (IDO 0 ~ IDO 15) while
the channel is in use, the current will flow
from the external voltage source to the card.
Take care to ensure that the current through
each GND pin does not exceed 500 mA.
The figure below shows how to connect an external output
load to the card’s isolated outputs.
