Product Short Description
Product Name: E5CD Series Digital Temperature Controller (1/16 DIN, 48 × 48 mm)
Product Introduction: The E5CD-RX2ADM-802 is a general-purpose digital temperature controller from OMRON’s E5CD series, designed for industrial automation applications such as packaging sealing machines and water-cooled extruders. It delivers the same control performance as the popular E5CC series while adding Adaptive Control, Automatic Filter Adjustment, and Water-Cooling Output Adjustment functions.

Functional Features:
- Adaptive Control: Automatically optimizes PID parameters in response to changes in system dynamics (ambient conditions, equipment aging, workpiece material changes)
- Automatic Filter Adjustment: Suppresses instability in surface temperature measurement common in sealing applications, improving sealing quality
- Water-Cooling Output Adjustment: Suppresses temperature variation causes in water-cooled extrusion processes
- Multi-SP Function: Stores up to 8 setpoint values (SP0–SP7), selectable via key operation or serial communication
- Diagnostic Data: Monitors power-on time, ambient temperature, and output ON/OFF cycle count
- Heater Breakage & SSR Fault Detection
- Draw-out screw-terminal block structure for easy maintenance without rewiring
Application Scenarios: Packaging machines (pillow-type, vertical form-fill-seal), water-cooled twin-screw extruders, heating/cooling controlled processes requiring precise temperature regulation.
Working Principle: The controller accepts a temperature sensor or analog signal at its input, compares the measured process value (PV) against the setpoint (SV), and computes a control action using 2-degree-of-freedom PID with auto-tuning. The resulting output drives a relay (or external SSR) to regulate the heating/cooling element. RS-485 communication enables integration with PLC systems for programless data exchange.
Installation Requirements: Panel cut-out 45 × 45 mm; mount in a control panel with the front face rated to IP66. Use a T2A 250 V time-delay fuse for power supply protection. Ensure ambient conditions stay within -10 to +55 °C and 25–85% RH.
Usage Precautions: Do not exceed the rated supply voltage range (85–110% of nominal). Avoid locations with freezing, condensation, or corrosive atmospheres. The relay output is rated for 3 A at 250 V AC resistive load—do not exceed this rating. When using for heater break detection, proper CT input wiring is required.
