Description
Allen-Bradley 1738-EP24DC ArmorPoint Expansion Power Module
The Allen-Bradley 1738-EP24DC serves as the primary 1738-EP24DC Expansion Power Module utilized to execute 24 VDC field power distribution across ArmorPoint I/O platforms. The module transfers field-side power to downstream I/O segments, allowing additional modules to be connected while maintaining power separation from the primary network adapter.

EtherNet/IP I/O Density Scaling
Within ArmorPoint distributed architectures, the 1738-EP24DC supports I/O density scaling by supplying additional field-side power to downstream module groups. This arrangement reduces loading on the primary adapter power segment and permits expansion of distributed I/O assemblies while maintaining the electrical distribution structure defined by the ArmorPoint platform. Network communication remains managed by the associated adapter while the 1738-EP24DC performs power-segmentation functions.
Frequently Asked Questions
Q: Does the 1738-EP24DC provide network communication functions?
A: No. The module is intended for field-power expansion only. Network communication is handled by the associated ArmorPoint network adapter.
Q: What is the maximum downstream current capacity supported by the module?
A: The specified downstream output capacity is up to 8 A at 40 deg C.
Q: Is the module electrically isolated?
A: The unit provides 50 V isolation and is tested at 1500 VAC for 60 seconds according to the published specification.
Field Installation Guidelines
-
Verify that the incoming field power source matches the specified 10 to 28.8 VDC input range before energizing the module.
-
Install the module within the designated ArmorPoint assembly sequence and ensure all mechanical latches are fully engaged.
-
Maintain sealed cable connections and enclosure integrity where IP65/IP66/IP67 protection is required.
-
Route power wiring separately from high-energy switching conductors to reduce conducted electrical noise.
-
Terminate cable shields according to site grounding practices and maintain a single-point grounding strategy where applicable.
-
Inspect field connectors periodically for moisture ingress, mechanical damage, and loose terminations.
-
De-energize field circuits before wiring modifications or module replacement activities.
