Drops into a 1/16 DIN hole without panel rework
The E5CC-CX3A5M-5804U: The 45.00 mm square cutout is the standard 1/16 DIN footprint — if the old controller was 1/16 DIN, this slides into the same hole without cutting the panel or drilling new mounting holes. Screw terminals match the wiring pattern of most panel-mount controllers; no crimp tool or special connector needed for the field wiring.
What the outputs actually drive
One analog output plus three relay outputs — the analog channel handles a 4-20 mA or 0-10 VDC retransmission or control signal to a SCR power controller or valve positioner, while the relays manage alarms, event states, or on/off heater contactors. The control method covers on/off for simple tank or oven applications and full PID with auto-tune for processes that need tight temperature regulation without overshoot.
RS-485 means it talks to the rest of the line
RS-485 with both CompoWay/F and Modbus protocols — the Modbus RTU option lets a PLC or SCADA poll the PV, setpoint, and status registers without a protocol converter. The dual-row 4-character LCD shows process value and setpoint simultaneously; the 0.600-inch upper character height is readable from across a machine bay.
IP66 front — hose it down
IP66 rating on the front face means the controller survives washdown cycles in food, beverage, or pharmaceutical lines — the gasket seals against the panel cutout, not just the bezel. Operating range of -10°C to 55°C covers most indoor plant-floor environments without derating; no heater or ventilation mod needed for the enclosure.
