That means one part number handles both temperature and analog process loops — no separate model for mA vs TC inputs. Control method is On/Off or full PID, so you can tune it for aggressive ramp-and-soak profiles or simple threshold switching without swapping hardware. ## Communications and outputs Four relay outputs give you separate control, alarm, and event channels — enough for a heating/cooling split plus a high/low alarm pair. The RS-485 port speaks both CompoWay/F and Modbus, so it drops into existing PLC networks without a protocol converter. The IP66 front panel rating means the display and keys survive washdown in food or chemical environments — the sealing is at the bezel, not the housing, so the rear terminals remain in the panel's dry side. ## Panel cutout and starter kit The 45.00 mm x 45.00 mm square cutout is the standard 1/16 DIN footprint — no special punch or adapter frame needed. The starter kit includes the controller, cable, and configuration software, so a first-off commissioning doesn't require separate ordering of accessories.","metaTitle":"Omron E5CC-RX3A5M-5803U Process/Temp Controller, PID, RS-485","metaDescription":"Omron E5CC-RX3A5M-5803U process/temperature controller.
