Core Specifications Category Details Product Type E5AC Series 1/8 DIN digital temperature controller (SSR voltage output, 3 alarms, HB/HS detection, 2 event inputs) Manufacturer Omron Automation Mounting Panel mount (48×96 mm cutout); screw terminal block Power Supply 100–240 VAC (50/60 Hz); power consumption: ~10 VA Input Type Universal (thermocouple K/J/T/E/R/S/B/N/L/U/PL II, Pt100/JPt100 RTD, 0–20 mA/4–20 mA/1–5 V/0–5 V/0–10 V analog) Display 4-digit dual LED (PV: red 10 mm; SV: green 5 mm); multi-segment status indicators Control Method ON/OFF or PID control with auto-tuning; heating/cooling mode selectable Control Output 1×12 VDC voltage (SSR drive, max 21 mA; short-circuit protection) Auxiliary Output 3×SPDT alarm relays (250 VAC 2 A resistive max each) Event Input 2 points (for remote SP, run/stop, reset, etc.) Heater Monitoring 1-phase heater burnout (HB) and SSR fault (HS) detection Sampling Period 50 ms Indication Accuracy Thermocouple: ±0.3% PV ±1 digit; RTD: ±0.2% PV ±1 digit; analog: ±0.2% FS ±1 digit Front Protection IP66 Operating Temperature -10°C to +55°C Certifications CE, RoHS compliant Weight ~220 g Dimensions 48×96×110 mm (depth) Key Functions & Advantages SSR Voltage Control & Universal Input 12 VDC SSR drive output enables fast, low-noise switching for precise temperature regulation, compatible with most industrial solid-state relays. Universal input covers a wide temperature range (-200°C to +2300°C for thermocouples, -200°C to +850°C for RTDs) and analog signals for flexible sensor/transducer integration. 3 independent alarm outputs support high/low temperature or process fault monitoring; 1-phase HB/HS detection prevents overheating and equipment damage. Flexible Event Inputs & User-Friendly Operation 2 event inputs enable remote setpoint adjustment, run/stop control, and alarm reset, enhancing system integration and automation. 48×96 mm panel-mount form factor fits standard control panels; screw terminals ensure stable wiring for vibration-prone environments. Large dual LED display ensures high visibility; front-panel keys with password protection prevent unauthorized parameter changes. 110 mm slim body saves space in control cabinets; IP66 front protection resists dust and water ingress for harsh industrial environments. Reliable Performance for Industrial Applications 50 ms high-speed sampling ensures rapid response to temperature changes for dynamic processes. Auto-tuning PID optimizes control parameters automatically, reducing setup time and ensuring stable performance across varying loads. Global certifications and robust design ensure compliance with international standards for industrial applications.
