The Omron E5EC-TRR4D5M-010 is a panel-mount process and temperature controller from the E5EC-T series, accepting inputs from RTDs and thermocouples (Types B, E, J, K, L, N, PLII, R, S, T, U, W) as well as 0–20 mA and 0–10 VDC analog signals. Its six relay outputs provide discrete on/off or PID control, with the relay count suiting applications that need multiple independent heating/cooling stages or alarm annunciation per the datasheet. The front panel carries an IP66 rating, meaning the display and keypad withstand direct hose-down and dust ingress — appropriate for food-processing, washdown, or outdoor cabinet installations where a standard NEMA 4X front is specified. The 24 VAC/DC supply keeps it compatible with control transformers or DC power supplies common in industrial panels.
Six relay outputs: each output is a dry-contact relay rated for switching loads directly — typically used for driving contactors, solenoid valves, or alarm indicators. The count of six means you can allocate, for example, two outputs for heating/cooling stages, two for alarm thresholds (high/low), one for event-driven output, and one spare, all without external relay expansion. Heater fault detection (included as a standard feature) monitors current draw on the heater circuit via an external CT and flags a broken heater or SSR short — a real time-saver on plastic injection or packaging lines where an undetected dead heater scrapes a batch. The event input allows external pushbuttons or PLC dry contacts to latch/unlatch the controller, change setpoint banks, or reset alarms without opening the panel door. The input range spans -200°C to 2300°C across thermocouple types, plus 0–20 mA and 0–10 VDC for process signals (pressure, flow, level). This means one part number covers both temperature and analog process loops — no need to stock separate controller families for each sensor class.
Panel cutout is 92.00 mm × 45.00 mm, the standard 1/8 DIN horizontal format. The controller slides in from the front and secures with the included bracket; no DIN-rail adapter is used. The IP66 front means the gasket seals against washdown; the rear of the unit is not sealed, so the panel enclosure must still provide the environmental seal on the back.
