The Omron E5CC-QX3A5M-003 is a compact temperature controller designed for precise thermal management in industrial applications. With a 1/16 DIN (48x48 mm) panel mount size, it offers versatile input options, including thermocouples (Types B, C, E, J, K, L, N, P, R, S, T, U, W) and RTDs (Pt100, JPt100). The controller supports linear analog inputs ranging from 0 to 10 V, 0 to 20 mA, 0 to 5 V, 1 to 5 V, and 4 to 20 mA, accommodating a wide range of sensors. Its main control output is a voltage pulse, suitable for driving external solid-state relays (SSRs). The E5CC-QX3A5M-003 operates on an AC supply voltage of 100 to 240 V and features a dual-line LCD display for clear status indication. It includes three alarm outputs and supports RS-485 communication, facilitating integration into complex control systems. The controller is equipped with heater burnout detection and SSR defect detection, enhancing system reliability. Its IP66 rating ensures protection against dust and water ingress, making it suitable for demanding industrial environments. The E5CC-QX3A5M-003 is part of Omron's E5CC series, known for their advanced control capabilities and user-friendly interfaces.
