Runs on 24VAC/DC supply, provides 3 relay outputs and voltage pulse for external SSR. RS-485 supports Modbus and CompoWay/F. ## Comparison to the E5CC-RX3A5M-003 The closest functional peer is the E5CC-RX3A5M-003, also in the E5CC family with the same sensor input range and RS-485. Two differences matter: the -RX3A5M-003 runs on 100–240VAC and packs four relay outputs instead of three. It lacks the voltage (SSR) drive output. If your panel supplies 24V and you need SSR control, the -QX3D5M-5803U is the correct choice. ## Panel Integration Panel cutout is a standard 45.00mm square; the IP66-rated front seals against dust and water spray. Screw terminals accommodate field wiring. No backplane power isolation needed—single 24VAC/DC connection supplies the controller and its 3-relay output circuits.","metaTitle":"Omron E5CC-QX3D5M-5803U Process Controller, 24VAC/DC, 3 Rela","metaDescription":"Omron E5CC-QX3D5M-5803U temperature/process controller, active production, 24VAC/DC supply, 3 relay + voltage (SSR) outputs, RS-485 Modbus, IP66 front, 45x45mm cutout.
