Core Specifications Category Details Product Type E5C4 series 1/16 DIN temperature controller (ON/OFF contact output, plug-in socket) Manufacturer Omron Automation Mounting Panel mount (45×45 mm cutout); plug-in socket (P2CF-08 front/P3G-08 back) for DIN-track or flush mounting Power Supply 100–240 VAC (50/60 Hz); power consumption: ~2 VA Input Type Thermocouple (K/J) or Platinum RTD (Pt100) (model suffix dependent: E5C4-R20K=K-type, E5C4-R20J=J-type, E5C4-R20P=Pt100) Display 3-digit LED (SV: red 14 mm); status indicator (control output ON/OFF) Control Method ON/OFF (fixed differential); no auto-tuning (manual differential adjustment) Control Output 1×SPST-NO relay (250 VAC 3 A resistive max; 30 VDC 3 A resistive max) Temperature Range K/J-type: 0–399 °C (1 °C resolution); Pt100: 0–99.9 °C (0.1 °C resolution) Indication Accuracy Thermocouple: ±1.0 °C ±1 digit; Pt100: ±0.5 °C ±1 digit Front Protection IP40 (with optional Y92A-48N watertight cover) Operating Temperature -10°C to +55°C (no condensation/icing) Certifications CE, UL, CSA compliant Dimensions 48×48×80 mm (W×H×D) Weight ~150 g Key Functions & Advantages Simplified Basic Control 1/16 DIN (48×48 mm) compact size fits standard panels; plug-in socket enables fast installation/ replacement without rewiring. Fixed ON/OFF differential (adjustable via front dial) ensures stable control for non-critical heating processes, reducing setup complexity. Clear 3-digit LED SV display and output status indicator enable at-a-glance monitoring and quick setpoint changes. Cost-Effective & Reliable Low power consumption (~2 VA) minimizes energy costs; 3 A relay output handles most small-to-medium heating loads. Plug-in design with P2CF-08/P3G-08 sockets supports flexible DIN-track or flush mounting, adapting to diverse panel layouts. Robust construction withstands industrial environments, with IP40 front protection (enhanced by optional watertight cover). Flexible Input & Integration Model suffixes (K/J/P) cover common thermocouple/RTD inputs, matching standard industrial sensor types. Wide 100–240 VAC power range suits global deployments; no complex programming—ideal for standalone systems or basic PLC integration.
