The Omron E5CC-RX0ASM-000, also cataloged as the E5CC Digital Temperature Controller, operates as a dedicated hardware component for closed-loop thermal regulation and analog process monitoring within industrial panel control loops.

Part Number Nomenclature & Configuration

• E5CC: 48 mm x 48 mm DIN panel-mount temperature controller chassis base.
• RX: Relay contact control output (250 VAC, 3 A resistive load).
• 0: Zero auxiliary alarm relay outputs configured.
• A: Operating supply voltage range of 100 to 240 VAC at 50/60 Hz.
• S: Screw terminal block connections provided on rear interface.
• M: Universal analog sensor input interface stage.
• 000: Standard feature set without option board expansion modules.

Hardware & Accuracy Specifications

High-Speed Signal Processing & Firmware Flash Compatibility

The embedded processing engine executes real-time input sampling at 50 ms intervals to calculate 2-PID parameters and prevent overshoot. Internal non-volatile memory ensures complete firmware flash compatibility during system parameter programming, storing setpoints, input scaling curves, and control response profiles without external battery power. Boot-up memory checks validate register blocks on power initialization, maintaining output relay integrity during AC mains voltage fluctuations.

Mounting Requirements & Field Wiring Directives

Panel Installation Procedure

• Cut a 45 mm x 45 mm square opening in the enclosure door; fit the rubber sealing gasket onto the front bezel before insertion to maintain IP66 panel protection.
• Push the chassis into the door cutout and push the mounting adapter forward from the rear until the ratchet locks hold the unit firm against the panel.

Electrical Wiring Guidelines

• Connect 100 to 240 VAC power and control output circuits to the rear screw terminals using insulated crimp lugs; tighten terminal screws to 0.5 N-m.
• Lay thermocouple and RTD sensor cables away from high-voltage motor wires, grounding the overall cable shield at a single panel earth point.

Frequently Asked Questions

• What primary control output configuration is provided on the E5CC-RX0ASM-000?

  The RX designation indicates a SPST-NO relay contact output rated for switching up to 250 VAC at 3 A under resistive loads.

• What sampling rate does the internal processor use for analog inputs?

  The controller samples incoming process variables and executes PID calculations at a 50 ms sampling cycle rate.

• Which sensor types are supported by the universal input stage?

  The input circuit accepts standard thermocouples, Pt100/JPt100 platinum RTDs, linear 4-20 mA current loops, and standard DC voltage signals.

• Does the E5CC-RX0ASM-000 incorporate auxiliary alarm contacts?

  No, the 0 designation in the model number confirms that no auxiliary alarm relays are installed on this hardware version.

• How are user setpoints preserved during a main power failure?

  Internal EEPROM non-volatile flash memory saves all operating parameter values, calibration constants, and setpoints indefinitely.

• What display accuracy is achieved when using thermocouple sensors?

  Thermocouple inputs maintain a measurement accuracy of (+/-0.3% of PV or +/-1 deg C, whichever is greater) +/-1 digit maximum.

• What panel cut-out dimensions are required for physical mounting?

  The unit fits standard DIN 48 mm x 48 mm cutouts, requiring a square panel opening measuring 45 mm x 45 mm.

• What ingress protection level is maintained at the panel door?

  When installed with the supplied rubber sealing ring, the front panel assembly meets IP66 water-resistant and dust-tight standards.
