Core Specifications Category Details Product Type E5EK Series 1/8 DIN digital temperature controller (modular single output, 1 alarm) Manufacturer Omron Automation Mounting Panel mount (48×96 mm cutout); modular output unit (removable) Power Supply AC 100–240 V (50/60 Hz); power consumption: ~8 VA Input Type Universal (thermocouple K/J/T/E/R/S/B/N, Pt100 RTD, 0–10 V/4–20 mA analog) Display Dual 4-digit LED (PV: white; SV: orange) Control Method ON/OFF or PID control with auto-tuning Control Output Modular: 1×SPDT relay (E53-R, 250 VAC 2 A), 1×SSR (E53-S, AC 75–250 V 1 A), 1×12 VDC voltage (E53-Q, 50 mA), 1×4–20 mA current (E53-C3), etc. Auxiliary Output 1×SPDT alarm relay (250 VAC 2 A) Event Input 1 point (remote SP, run/stop, reset) Sampling Period 50 ms Indication Accuracy ±0.3% PV ±1 digit (thermocouple/RTD); ±0.2% FS ±1 digit (analog) Front Protection IP66/NEMA 4X (waterproof/dustproof) Operating Temperature -10°C to +55°C Certifications CE compliant Weight ~250 g Key Functions & Advantages Modular Output Flexibility Swappable E53-series output units (relay/SSR/voltage/current) adapt to diverse load types without replacing the main controller. Universal input covers -200°C to +2300°C (thermocouple), -200°C to +850°C (RTD), and analog signals for versatile sensor integration. 1 auxiliary alarm relay enables over/under temperature or sensor break monitoring. Reliable Control & Diagnostics PID with auto-tuning optimizes temperature stability for heating/cooling processes. Output ON/OFF counter tracks relay/SSR lifespan for preventive maintenance. IP66/NEMA 4X front protection resists water/dust in harsh industrial environments. Easy Configuration & Maintenance 48×96 mm (1/8 DIN) panel-mount size fits standard cutouts; modular design simplifies output unit replacement. Front-panel keys with password protection prevent unauthorized parameter changes.
