Eaton EASY-E4-UC-16RE1 easyE4 Control Relay, 8 DI, 4 AI, 8 Relay Outputs, Ethernet, LCD, DIN Rail

With 8 digital inputs, 4 analog inputs (0-10V / 0-20mA), and 8 relay outputs rated 8 A each, the Eaton EASY-E4-UC-16RE1 packs 16 I/O points into a compact DIN-rail control relay. It runs on 12/24 V DC or 100-240 V AC and includes an integrated Ethernet port and web server for remote monitoring.

Overview

The EASY-E4-UC-16RE1 belongs to Eaton's easyE4 series, a line of programmable logic controllers designed for small automation tasks. It offers 1000 lines of program memory (FBD/LD) or 1000 blocks (EDP), a real-time clock, an SD card slot for data logging and program backup, and an LCD display for local status. Programming is done via easySoft 7 software, and the unit supports Modbus TCP and easyNet communication.
