E5EC-PR2ASM-804 Digital Temperature Controller with SSR Output and 1/16 DIN Size

Product Overview

The Omron E5EC-PR2ASM-804 is a high-performance digital temperature controller engineered for industrial and commercial applications requiring precise thermal regulation. As part of the renowned E5EC series, this model delivers exceptional accuracy (±0.3% of full scale) and advanced PID control functionality. Its compact 48×48mm DIN form factor makes it ideal for panel mounting in space-constrained environments while maintaining robust operation in temperatures from 0 to 55°C.

Key Features and Benefits

• Universal Input Compatibility: Supports all major temperature sensor types including thermocouples (K, J, R, S, B, E, T, N, W), RTDs (Pt100, JPt100), and analog signals (0–10V, 0–20mA, 4–20mA) for maximum application flexibility.
• Advanced Control Algorithm: Incorporates Omron's proprietary PID control with auto-tuning capability, ensuring optimal temperature stability and reduced overshoot in dynamic thermal processes.
• Multi-Output Configuration: Features 2 relay outputs (SPST-NO 5A 250V AC), 1 voltage pulse output (12-24V DC), and 1 current output (4-20mA) for comprehensive system integration.
• High-Visibility Display: Bright red LED backlight illuminates the 4-digit, 7-segment display for clear visibility in all lighting conditions.
• Robust Construction: Industrial-grade components ensure reliable operation with a power consumption of ≤6VA and protection against electrical noise (2,000V AC for 1 minute).
• Global Power Compatibility: 100-240V AC power supply with 50/60Hz operation simplifies international deployment.
• Standard Warranty: Backed by Omron's 1-year manufacturer warranty against defects in materials and workmanship.
