The onboard RS-485 speaks CompoWay/F and Modbus, so it talks to a PLC or SCADA without an extra gateway. And it ships with a starter kit—controller, programming cable, and software—so you can have it loop-tuned before the panel's even buttoned up. ## How it stacks up The big difference between this 24V unit and the E5CC-RX3A5M-003 (100-240VAC) is the supply voltage. If your panel's already wired for 120V, you'll need that one instead. This 24V version is for machines that run on low-voltage control power—common in food processing, packaging, and anything with high contact protection. It keeps the same relay bank (4), same RS-485, same 45mm square cutout, and the same IP66 front. The starter kit is only bundled with this order code, so if you're starting from scratch, this saves pulling cables and software separately.","metaTitle":"Omron E5CC-RX3D5M-5803U Temp Controller, 24V","metaDescription":"Active E5CC-RX3D5M-5803U process controller with 4 relay outputs, RS-485, IP66, input range -200°C to 2300°C. 24VAC/DC supply.
