I/O Expansion Module · 8 digital inputs 8 relay outputs 12/24 V DC and 24 V AC screw terminals · Eaton EASY-E4-UC-16RE1

SKU: EAT-EASY-E4-UC-16RE1

Eaton EASY-E4-UC-16RE1 is an easyE4 I/O expansion module with 8 digital inputs and 8 relay outputs for 12/24 V DC and 24 V AC control systems. It is used to add field I/O to compatible easyE4 controllers where screw terminals are preferred for panel wiring and service access.

What this product is for

This I/O expansion module adds 8 digital inputs and 8 relay outputs to compatible Eaton easyE4 control relays in machine control, small process control, and panel-built automation systems.

Use for

Use for expanding available field inputs and relay outputs on 12/24 V DC or 24 V AC easyE4 installations. Common applications include pump panels, fan control, small machinery, sequencing, alarm handling, and retrofit control panels.

Avoid for

Avoid for standalone control without a compatible easyE4 base unit. Do not use where transistor outputs, analogue I/O, or a different terminal style are required.

Best for

Best for electricians and panel builders who need additional digital I/O on an easyE4 system and want screw terminal field wiring for straightforward installation, troubleshooting, and replacement.

Installed in

Typically installed in industrial control panels, OEM equipment, utility panels, and building automation enclosures. Module size is approximately 2.8 x 3.5 x 2.3 in (72 x 90 x 58 mm), which helps when planning DIN rail panel space.

Why this product exists

It expands an easyE4 controller without changing the main control platform, allowing more field devices to be connected as the machine or process grows. This can reduce redesign time on small automation jobs.

Compared with similar products

Compared with push-in terminal versions, this EASY-E4-UC-16RE1 uses screw terminals, which some panel shops prefer for serviceability and existing wiring practices. Compared with base easyE4 controllers, this is an expansion module only and depends on a compatible host unit.
