Overview
The Eaton easyE4 is the fourth generation of the easy control relay, a nano PLC for small machines, building and pump control. The EASY-E4-UC-12RC1 base device has 8 digital inputs (4 also usable as 0–10 V analog), 4 relay outputs rated 8 A, a universal 12–24 V DC / 24 V AC supply and an Ethernet port with web server and Modbus TCP; a display and keypad allow on-device editing. Up to 11 expansion units add digital, analog and temperature I/O to 188 points, and easySoft 8 programs it in ladder, function block, structured text or the easy device programming (EDP) language. It replaces the easy500/700/800 series with a migration path for existing programs.
Key features
- 8 DI (4 as 0–10 V AI), 4 relay outputs 8 A; 12–24 V DC / 24 V AC supply
- Ethernet with web server, Modbus TCP, NET communication between easyE4 devices
- Expandable with up to 11 units to 188 I/O; temperature modules for Pt/Ni/TC
- easySoft 8: ladder, FBD, ST, EDP; display with keypad for on-site changes
- microSD card for program/data; real-time clock; replaces easy500/700/800
Typical applications
- Pump and fan control with alternation and time schedules
- Small machine and conveyor control
- Building services: lighting, HVAC, access
- Replacement of easy800 and timer/relay logic

Frequently asked questions
Can I migrate an easy800 program to easyE4?
Yes. easySoft 8 imports easy800 programs and converts them; wiring differs slightly, and we provide the cross-reference.
Is a display needed?
The -12RC1 version has a display and keypad; the -12RCX version without display is cheaper for programs that never need local editing.
Is the easyE4 available from stock, and what is the lead time?
Typically 1–2 weeks from Eaton regional stock. We confirm with the quotation.
