42639
The FlexArmor I/O modules (Cat. No. 1798-OB4E & 1798-OB8E)
mount in a FlexArmor Baseplate. Use compatible sealed cordsets to
connect all field side wiring.
The 1798-OB4E module provides connections for up to 4 outputs.
The 1798-OB8E module provides connections for up to 8 outputs.
Both of these modules have four 12 mm connectors. Outputs are 24V
dc configured for sinking devices. A diagnostic feature for both
modules includes output short-circuit detection.
Package Contents
Your package contains:
• 1 FlexArmor -OB4E or -OB8E module

Install Your FlexArmor I/O Module
To install the module:
• Install the modules into the Baseplate
• Connect the cordsets
• Communicate with the module
These steps are explained in more detail in the following
procedures.
For instructions on how to mount the FlexArmor Baseplate,
refer to publication no. 1798-IN003A-EN-P.
Install the Modules into the Baseplate
To install the modules into the Baseplate:
1. Hold the module at an angle and engage the top of the
module in the indention on the rear of the Baseplate.
2. Press the module down flush with the panel until the locking
lever locks.
3. Repeat these steps for each I/O module and each remaining
Baseplate I/O slot.
IMPORTANT
Screw down the module retaining screws to ensure IP67 compliance.
IMPORTANT
I/O modules can be installed in any slot location
to the right of the adapter module. The adapter is
capable of addressing up to eight I/O modules.
• Torque the screws to 0.5-0.7 Nm. (4.43 - 6.2
inch pounds).
• Dust caps must have 4 inch pounds of torque
to maintain IP67 compliance.

Connect the Cordset to the FlexArmor Module
These modules use 5 pin micro (12mm) style PCB mounted
connectors.
Four micro caps cover the I/O connectors on both your modules.
Remove the caps and connect your cables to the appropriate ports.
Keep the caps in place on any unused connector to maintain the IP67
rating.
Refer to publication no. 889-CP0021A-EN-P for compatible Rockwell
Automation cables and cordsets.
A pinout diagram for the connectors is shown below.

Publication 1798-IN002A-EN-P - January 2001
• Make sure all connectors and caps are
securely tightened to properly seal the
connections against leaks and maintain IP67
requirements.
• For maximum noise immunity, input and
output cable return wires must be properly
terminated. When inputs and outputs are
connected in loopback, return wires should
be connected together.
• I/O cable length should be less than 30
meters.

Communicate with Your FlexArmor System
The FlexArmor DeviceNet adapter module supports multiple
communication choices. The network master makes the actual
communication choice. The choices are:
Polled - data is sent by the adapter in response to received data.
Strobe - data is sent by the adapter in response to the strobe
command. The single bit allocated to the adapter in the strobe
message is not used. If the configured size of the input data (sent
from the adapter) is greater than 8 bytes, the strobe connection
establishment will fail. In this case, the input size must be
re-configured to 8 bytes or less.
Change of State - data is sent by the adapter based on detection of
any changed value within the input data. Data is independently
received based on change of state from the sender. Data in both
directions can be acknowledged or unacknowledged depending on
the run time configuration of the system.
Cyclic - data is sent cyclically by the adapter based on a configured
time value. Data is independently received cyclically from the sender.
Data in both directions can be acknowledged or unacknowledged
depending on the run time configuration of the system.
