The Omron E5CC-RX2DSM-800 is a panel-mount digital temperature controller from the E5CC series, running on a 24VAC/DC supply and delivering three relay outputs for on/off or PID control loops. It accepts a wide range of sensor inputs — RTD, plus thermocouple types B, E, J, K, L, N, PLII, R, S, T, U, W — covering process spans from -200°C up to 2300°C, as well as 0-20mA or 0-10VDC analog signals. The dual-color LCD backlit display shows two rows of four characters each, with 0.600" and 0.280" character heights for the main and secondary values. The IP66-rated front panel withstands washdown environments, making it a fit for food, beverage, or pharmaceutical lines where hose-down cleaning is routine.
The three relay outputs are the key differentiator here: this variant gives you three discrete SPDT relay contacts for control, alarm, or event outputs, versus the two-relay-plus-SSR-drive arrangement on the E5CC-QX2ASM-801. If your application needs a third dedicated alarm relay or a separate cooling output without adding an external module, the RX2DSM-800 saves a DIN-rail slot. The 24VAC/DC supply also distinguishes it from the 100-240VAC siblings — useful in panels where a 24V control transformer is already present, or where low-voltage operation is preferred for safety. The square 45.00mm x 45.00mm panel cutout matches the standard 1/16 DIN footprint, so it drops into existing punch-outs without adapter hardware. Screw-terminal wiring keeps field replacement straightforward — no special crimp tools or octal-socket alignment needed, unlike the plug-in variants in the same family.
