This document describes the features and functions of the E5CN/E5CN-U digital temperature controllers. It is easy to use, reliable, and has more functions, including 11-segment displays. It can be used for voltage outputs for controlling heat and cold, and can also be used for alarms. It also has features such as fast sampling and transfer outputs.
The Omron E5CN/E5CN-U series are compact 48 × 48 mm digital temperature controllers with 11‑segment displays. They support both thermocouple/RTD (multiple) inputs and analog inputs, offering fast 250 ms sampling, various output types (relay, voltage for SSR, current) and optional modules such as heater‑break detection and long‑life relays.
The document provides reference coding, selection tables, detailed electrical specifications, communication settings (RS‑485), environmental limits, and installation precautions, helping users select the right configuration and integrate the controller into PLC or monitoring systems. This manual is written in Spanish.

The controller samples at a period of 250 ms.
The series offers relay (R), voltage for SSR (Q), current (C) and long‑life relay (Y) outputs.
The E5CN‑U model consumes up to 6 VA.
The front panel of the E5CN‑U is equivalent to IP50.
