Core Specifications Category Details Product Type E5AK Series 1/4 DIN digital temperature controller (discontinued: end of production April 2011)オムロン Manufacturer Omron Automation Mounting Panel mount (96×96 mm cutout); plug-in terminals Power Supply 100–240 VAC (50/60 Hz); power consumption: ~10 VA Input Type Universal input (TC: K/J/T/E/R/S/B/N/L/U/W/PLII; RTD: Pt100/JPt100; voltage: 1–5 VDC/0–5 VDC/0–10 VDC; current: 4–20 mA/0–20 mA) Display Dual 4-digit LED (PV: red, SV: green); clear process/set value visibility Control Method PID control with auto-tuning, ON/OFF control Control Output Configurable via E53 modules: relay (SPDT 250 VAC 3 A), SSR driver (12 V DC/20 mA), current (4–20 mA/0–20 mA)オムロン Event Inputs 4-point event inputs (for run/stop, setpoint shift, auto-tuning trigger) Sampling Period 200 ms Indication Accuracy ±0.3% PV ±1 digit Front Protection IP40 (panel-mounted) Operating Temperature -10°C to +55°C Certifications CE, UL, CSA compliant Weight ~300 g Key Functions & Advantages Flexible I/O Configuration Universal input supports diverse sensors and process signals, simplifying integration into existing systems. 4-point event inputs enable external control of key functions (e.g., start/stop, setpoint adjustment), enhancing operational flexibility. Configurable output modules (relay/SSR/4–20 mA) adapt to various load types (heaters, contactors, valves)オムロン. Precise PID Control PID with auto-tuning minimizes overshoot/undershoot, ensuring stable temperature regulation in dynamic processes. Dual LED display provides real-time monitoring of process and set values for quick status checks. Easy Maintenance & Replacement Plug-in terminals allow tool-free installation and module swapping, reducing downtime during maintenance. Nonvolatile memory retains configurations during power loss, preventing data loss and simplifying restarts.
