Prevent Electrostatic Discharge
The analog output module is sensitive to electrostatic discharge.
ATTENTION: Electrostatic discharge can damage
integrated circuits or semiconductors if you touch
!
backplane connector pins. Follow these guidelines
when you handle the module:
• Touch a grounded object to discharge static potential
• Wear an approved wrist-strap grounding device
• Do not touch the backplane connector or
connector pins
• Do not touch circuit components inside the module
• If available, use a static-safe work station
• When not in use, keep the module in its
static-shield box

1770-4.1
This equipment is classified as open equipment and must be mounted
in an enclosure during operation to provide safety protection.
The module receives its power through the 1771 I/O power supply
and requires 2A from the backplane.
Add this current to the requirements of all other modules in the I/O
chassis to prevent overloading the chassis backplane and/or
backplane power supply.

Determine Module Placement in the I/O Chassis
Install the Module and the Remote Termination Panel
Place your module in any I/O module slot of the I/O chassis except
for the extreme left slot. This slot is reserved for PC processors or
adapter modules.
ATTENTION: Do not insert or remove modules from
the I/O chassis while system power is ON. Failure to
!
Group your modules to minimize adverse affects from radiated
electrical noise and heat. We recommend the following.
observe this rule could result in damage to module
circuitry.
• Group analog input and low voltage dc modules away from ac
modules or high voltage dc modules to minimize electrical noise
interference.
• Do not place this module in the same I/O group with a discrete
high-density I/O module when using 2-slot addressing.
ATTENTION: Remove power from the 1771 I/O
chassis backplane and field wiring arm before
!
removing or installing an I/O module.
• Failure to remove power from the backplane or
wiring arm could cause module damage, degradation
of performance, or injury.
• Failure to remove power from the backplane could
cause injury or equipment damage due to possible
unexpected operation.
Place the module in the card guides on the top and bottom of the chassis that guide the module into position.

Important: Apply firm even pressure on the module to seat it into its
backplane connector.

Snap the chassis latch over the
top of the module to secure it.
Swing the chassis locking bar
down into place to secure the
modules. Make sure the locking
pins engage.

Key the Backplane Connector
Place your module in any slot in the chassis
except the leftmost slot which is reserved for
processors or adapters.
Position the keying bands in the backplane connectors
to correspond to the key slots on the module.
Place the keying bands:
between 26 and 28
between 32 and 34
You can change the position of these bands if
subsequent system design and rewiring makes
insertion of a different type of module necessary.

Connect the Cable to the Module
1. Slide the locking bar up.
2. Insert the cable connector into the mating connector on the
front of the module.
3. Slide the locking bar down over the mating pins on the
module to lock the connector onto the module.
