The E5EC-CX4D5M-004 provides an extra relay, runs on 24 VAC/DC, and requires a larger rectangular panel hole. A cabinet designed for the E5CC cannot accept this controller without re-cutting the panel. Another 24 VAC/DC variant, E5CC-CQ3D5M-005, adds a voltage output for external SSR but retains the three-relay count and 45 mm square cutout. Neither is a drop-in substitute due to the cutout and output-count differences. Because it is an active, factory-supported part, we source it against a quoted lead time from the Omron channel. Submit an RFQ for your BOM line; we can confirm delivery schedule without last-time-buy constraints.","metaTitle":"Omron E5EC-CX4D5M-004 Process/Temp Controller, 24VAC/DC, 4 R","metaDescription":"Active Omron E5EC-CX4D5M-004 process/temperature controller. 24VAC/DC supply, 4 relay + analog outputs, RS-485 Modbus/CompoWay/F, PID control, IP66 front.
