Omron E5CC-CX3A5M-004 E5CC Digital Temperature Controller

Description

Precision thermal loop management is achieved through the Omron E5CC-CX3A5M-004, a compact 48 x 48 mm (1/16 DIN) digital temperature controller engineered for high-speed, stable PID execution. Featuring a high-contrast white LCD display with 15.2 mm character height, this controller ensures clear process value (PV) visibility even in low-light industrial environments. It supports high-speed sampling at 50 ms, allowing immediate response to thermal fluctuations in demanding closed-loop systems.

The unit features a universal input structure, allowing seamless connection of various thermocouples, RTDs, or analog voltage/current sensors without requiring hardware modifications. It is equipped with a linear current control output, three auxiliary outputs, and an integrated RS-485 communications interface, making it an excellent node for distributed control architectures using PLC or SCADA supervisory systems.

Features

• Universal Sensor Input: Direct connection for standard thermocouples, platinum resistance thermometers (RTD), and analog current/voltage signals.
• High-Speed Control Loop: Fast 50 ms sampling period provides rapid feedback processing for dynamic thermal systems.
• Linear Current Output: Dedicated analog control output (4-20 mA or 0-20 mA) for modulation of SCR power controllers, control valves, or variable speed drives.
• Enhanced Connectivity: Integrated RS-485 serial communication port supporting Modbus/RTU and CompoWay/F protocols for PLC integration.
• Multiple Event Inputs: Includes two digital event inputs for remote operation, run/stop toggling, or multi-SP selection.
• Auxiliary Outputs: Three independent relay outputs sharing a common terminal, configurable for various alarm types and status outputs.
• Secure Construction: Standard screw terminal connection block supplied with a protective terminal cover.

Applications

• Plastic extrusion and injection molding temperature control.
• Packaging machinery, shrink tunnels, and heat sealing systems.
• Industrial heat treatment furnaces, kilns, and drying ovens.
• Food processing machinery, pasteurizers, and industrial fryers.
• Environmental chambers and laboratory testing equipment.

Installation Guidelines

• Panel Mounting: Install into a standard 45 x 45 mm square panel cutout. Slide the mounting adapter over the controller from the rear and tighten until secure.
• Wiring Isolation: Maintain separation between input sensor signal wiring, communication cables, and high-voltage power lines to reduce electromagnetic interference.
• Ambient Environment: Ensure the installation area remains within the operating limit of -10 to 55 degC, and maintain sufficient ventilation space around the controller.
• Terminal Protection: Securely attach the provided screw terminal cover to prevent accidental contact with live electrical lines.

Compliance and Certifications

• CE Mark
• UL Listed / cULus
• RoHS Compliant
