Omron E5AC-TQX4ASM-080 E5AC-T Digital Temperature Controller

Description

Optimizing thermal process regulation with high-resolution control, the Omron E5AC-TQX4ASM-080 is an industrial-grade digital program temperature controller designed for precise DIN-panel integration. This 1/4 DIN (96 x 96 mm) controller is engineered to handle complex thermal profiles, featuring programmable ramp-and-soak capabilities across multiple patterns and segments. Equipped with a universal input structure, it natively supports various thermocouple types, platinum resistance thermometers (RTDs), and analog current or voltage signals.

The device leverages a high-speed 50-millisecond sampling period, delivering rapid PID calculations to correct thermal deviations in highly dynamic environments. Control output 1 provides a 12 VDC voltage output specifically configured for driving external Solid State Relays (SSRs), while four independent auxiliary relay outputs handle alarms, limit actions, or basic system interlocks. For network integration, this model includes built-in RS-485 serial communication, enabling seamless connection with PLC and SCADA platforms.

Features

• High-Visibility Display: Large, high-contrast white PV display with 25 mm character height for easy reading from a distance.
• Program Profile Control: Supports step, ramp, and soak profiles with up to 256 program segments (arranged in up to 8 patterns).
• Fast Sampling Rate: 50 ms sampling cycle time ensures high responsiveness in critical thermal processes.
• Universal Input Compatibility: Accepts thermocouples (K, J, T, E, L, U, N, R, S, B, W, PL II), RTDs (Pt100, JPt100), and analog voltage/current signals.
• Dual Tuning Modes: Built-in autotuning (AT) and self-tuning (ST) algorithms for automated optimization of PID constants.
• Advanced Diagnostics: Capable of detecting loop breaks, heater burnouts, and sensor failures.

Applications

• Heat treatment ovens, industrial kilns, and annealing furnaces.
• Packaging, shrink-wrapping, and plastic extrusion machinery.
• Semiconductor wafer processing and cleanroom environmental chambers.
• Food pasteurization and chemical processing vessels.

Connections and Interfaces

Installation Guidelines

• Prepare a standard 1/4 DIN cutout measuring 92 mm x 92 mm in the mounting panel.
• Insert the controller through the cutout and secure it firmly using the provided mounting fixtures. Tighten screws evenly.
• For wire connections, use M3 crimp terminals. Ensure terminal screws are tightened to a torque of 0.43 to 0.58 N-m to maintain secure electrical contact.
• To mitigate electromagnetic interference, run thermocouple and signal lines separately from AC power supply and load cables.

Compliance and Certifications

• CE Mark
• UL Listed / cUL Listed
