Omron E5CSV-R1T-500 1/16 DIN Digital Temperature Controller

The Omron E5CSV-R1T-500 is a highly versatile, compact 1/16 DIN digital temperature controller engineered for precision process control and thermal protection across industrial automation frameworks. Part of Omron’s renowned E5CSV series, this unit integrates multi-input sensor capabilities with a simplified layout that features both advanced 2-PID control (with integrated auto-tuning) and simple ON/OFF regulation.

As shown in the file “Untitled design – 2026-06-21T161708.587.jpg”, the controller features a prominent 3.5-digit, 7-segment red LED display with a high-visibility character height of 13.5 mm to ensure operators can quickly track temperature variables at a glance. The front panel contains tactile membrane keys for seamless manual configuration and an explicit deviation status indicator alongside output and alarm LEDs. This specific “-500” designation is equipped with a specialized finger-protection terminal cover on the rear to isolate wiring connections and maximize safety during maintenance.

Key Features

Universal Multi-Input Sensor Architecture: Wire-selectable configuration supports multiple thermocouple profiles (K, J, L, T, U, N, R) as well as platinum resistance thermometers (Pt100, JPt100), ensuring broad application adaptability without hardware replacements.
Advanced 2-PID Tuning & Self-Tuning: Features smart PID parameter generation via on-demand auto-tuning, allowing the controller to self-adjust to dynamic thermal environments and eliminate temperature overshoot.
Rear Finger-Protection Cover: The “-500” safety package includes a protective terminal block shield that minimizes electrical shock hazards from the active rear wiring paths.
Robust NEMA 4X / IP66 Waterproof Front Face: Designed to brave demanding factory conditions with a moisture-resistant and dust-tight front pane that handles aggressive industrial washdowns safely.
Configurable 8-Mode Alarm Output: Equipped with a dedicated secondary SPST-NO relay loop that can be assigned across eight distinct warning settings for absolute or deviation boundary monitoring.
Tamper-Resistant Key Protection: Outfitted with a “Setting Change Prohibit” lockout function to prevent unauthorized panel operators from accidentally modifying critical thermal thresholds.
