It has four relay/analog outputs for controlling heaters, valves, or alarms, plus an event input for external triggers. The tri-color LCD shows four characters per row, and the controller communicates via RS-485 using CompoWay/F or Modbus protocols. A rectangular 92 × 45 mm panel cutout is required, and the front face is rated IP66 for washdown environments. The most frequent cross-shop candidate is the smaller E5CC-CX3A5M-004, also from Omron. That unit fits a 45 × 45 mm square cutout and provides three relay/analog outputs instead of four. The E5EC uses the same operating range and universal input, but the larger rectangular footprint gives an extra control channel and a taller display (18 mm versus 15.2 mm for the top row). If your panel layout has a 92 × 45 mm slot and you need four outputs, the E5EC drops straight in. If you’re replacing an E5CC, the cutout is different — no easy swap without panel modification. ## Integration notes Mount the unit in a panel with the rectangular 92 × 45 mm cutout. Use screw terminals for power (100–240 VAC) and all wiring. The RS-485 bus defaults to CompoWay/F; set Modbus via the menu. The tri-color backlight can be programmed to change on alarm or process condition. The event input can be used to latch a second setpoint or reset latched alarms. Operating temperature is –10 to 55°C; derate display brightness at the high end. IP66 front tightens against hose-down, but the rear terminals remain behind the panel.","metaTitle":"Omron E5EC-CX4A5M-014 Process Controller, 4 Outputs, RS-485","metaDescription":"Active Omron E5EC-CX4A5M-014 process temperature controller with PID control, 4 relay/analog outputs, RS-485 Modbus, IP66, 92x45 mm panel cutout.
