The E5CN Digital Temperature Controller is a compact, intelligent temperature controller that features auto-tuning and self-tuning capabilities, which can even be performed during self-tuning. The controller is available for heating or heating/cooling control and includes an event input that allows multiple SP selection and run/stop functionality. The E5CN's water-resistant construction is NEMA4 (equivalent to IP66) and offers a variety of temperature inputs, including thermocouples, platinum resistance thermometers, non-contact temperature sensors, and analog inputs. The controller meets UL, CSA, IEC, and CE standards.
This manual covers the Omron E5CN digital temperature controller, detailing its features such as auto‑tuning, heating/cooling control, multiple sensor inputs, and NEMA4 (IP66) water‑resistant construction. It includes ordering information, option boards, accessories, and full technical specifications.
The document also explains operation procedures, initial setup, communication settings (RS‑485), safety precautions, and installation guidelines, helping users install, configure, and maintain the controller safely and effectively.

The E5CN uses RS‑485 (two‑wire, half‑duplex) communication.
The controller operates from 100 V to 240 V AC at 50/60 Hz.
Heating and cooling functions are available for models with two alarm points.
It accepts thermocouples (K, J, T, E, L, U, N, R, S, B), platinum resistance thermometers (Pt100, JPt100), and non‑contact temperature sensors.
