I/O Expansion Module · 4 Digital Inputs 4 Relay Outputs Screw Terminals · Eaton EASY-E4-UC-8RE1
I/O expansion module for Eaton easyE4 control relays with 4 digital inputs, 4 relay outputs, and screw terminals. Supports 12/24 V DC and 24 V AC control voltage for machine control and panel automation applications.
What this product is for
The EASY-E4-UC-8RE1 is an I/O expansion module used to add field inputs and relay outputs to compatible Eaton easyE4 control relays. It is intended for industrial control panels, small machine automation, and building control applications where additional hardwired points are required.
Use for
Use for expanding an easyE4 system with 4 digital inputs and 4 relay outputs. Commonly used for status inputs, limit switches, pushbuttons, pilot devices, and switching control loads through relay contacts in OEM panels and retrofit control assemblies.
Avoid for
Avoid for standalone control without a compatible easyE4 base unit. Also avoid where a solid-state output type, safety-rated control, or environmental protection beyond a standard control enclosure is required.
Best for
Best for electricians, panel builders, and automation contractors who need a compact expansion module with screw terminals for straightforward field wiring and serviceability.
Installed in
Typically installed on DIN rail inside industrial control panels, machinery panels, and building automation enclosures. The housing is approximately 1.4 in wide (35.5 mm), 3.5 in high (90 mm), and 2.3 in deep (58 mm), which helps when panel space is limited.
Why this product exists
This module expands the available I/O on an Eaton easyE4 controller without changing the main control platform. It gives contractors a practical way to add more field points while keeping the same programming environment and system family.
Compared with similar products
Compared with push-in terminal versions, this model uses screw terminals for conventional control wiring practices. Compared with input-only or transistor-output modules, this version combines 4 digital inputs with 4 relay outputs, which can reduce the number of separate modules needed in smaller control schemes.
