Panel fit and what it talks to
This E5EC-CC4D5M-004 drops into a standard 92x45 mm rectangular panel cutout — the same 1/4 DIN footprint as other E5EC family members, so no rework if you're swapping from a sibling like the E5EC-QR4D5M-010. Screw terminals on the back mean you can land field wiring without a crimper or special tool — handy when the panel is already wired and you're just swapping the controller. The IP66 front panel rating means it handles washdown spray from the front — good for food, beverage, or any line where hoses come out at the end of shift.
What it controls and how it connects
It reads thermocouple types B, E, J, K, L, N, PLII, R, S, T, U, W, plus RTD, and also accepts 0-20 mA or 0-10 VDC analog signals — so it covers both temperature and linear process inputs in one unit. Control method is PID or On/Off — PID for tight thermal loops (oven, extruder, injection mold), On/Off for simple limit or alarm functions. Outputs are mixed: two analog channels for driving SCRs or valve positioners, plus four relay outputs for on/off control, alarms, or event sequencing. The event input lets an external dry contact trigger a ramp/soak hold, alarm reset, or setpoint change without touching the front panel — useful for tying into a safety interlock or remote E-stop circuit.
Fieldbus and BOM-fit note
RS-485 with CompoWay/F and Modbus protocols — hooks into a PLC or SCADA network for setpoint download, PV readback, and alarm acknowledgment over the same two wires. Supply voltage is 24 VAC/DC — common on most control panels; no separate 100-240 VAC power supply needed if your panel already runs 24 V. Operating temperature range -10°C to 55°C — fine for indoor electrical rooms and most production-floor enclosures, but don't mount it in an unheated outdoor cabinet in a northern winter.
The closest functional sibling in the E5EC family is the E5EC-QR4D5M-010, which trades the two analog outputs for a voltage (SSR drive) output plus heater fault detection. If your application uses external SSRs instead of analog SCRs, that variant may save a wiring point.
