The Omron E5CN-HQ2M-500-AC100-240, also cataloged as the E5CN-HQ2M-500 Temperature Controller, operates as a dedicated hardware component for closed-loop thermal process monitoring and control within automation panel architectures.

Part Number Code Structure

The specific hardware configuration for this module breaks down as follows based on series naming conventions:

• E5CN: 1/16 DIN (48 x 48 mm) digital temperature controller platform housing.
• H: High-performance / high-resolution controller sub-series generation.
• Q: Voltage output for driving SSR (Solid State Relay) control circuits.
• 2: Two auxiliary alarm contact outputs.
• M: Option unit mounting capability (supports communication and event inputs).
• 500: Terminal cover included with finger-safe protection structure.
• AC100-240: Rated supply voltage range operating from 100 to 240 VAC.

Core Technical Characteristics

High-Speed Sampling & Logic Operation Integration

The unit provides high-speed sampling cycles down to 60 ms to ensure tight process regulation in dynamic thermal loops. Built-in logic operations (AND, OR, and signal delay parameters) configured via CX-Thermo software allow flexible signal processing without requiring external relay logic. Internal firmware flash compatibility supports dynamic memory retention and Control Output ON/OFF Counter logging for preventive maintenance on external switching hardware.

Included Standard Items

• 1 x Omron E5CN-HQ2M-500-AC100-240 Temperature Controller
• 1 x Mounting bracket set
• 1 x Terminal cover (attached)
• 1 x Instruction manual

Panel Mounting & Wiring Procedure

• Cut out a standard 45 x 45 mm square opening in the front enclosure panel.
• Insert the controller chassis through the panel cutout from the front side.
• Slide the mounting adapter from the rear until it latches tightly against the inner panel wall.
• Connect field wiring to the rear screw terminals using crimped spade or ring lugs.
• Keep thermocouple compensating leads and signal cables isolated from heavy motor or heater power lines to prevent induced noise.
• Verify correct supply voltage matching (100 to 240 VAC) prior to applying system power.

Technical Support FAQ

• What is the sampling cycle speed for process input updates?

  The internal input sampling cycle executes every 60 ms for rapid PV calculation.

• Does the controller accept universal sensor input types?

  Yes, thermocouple, platinum resistance thermometer, analog current, and voltage inputs are selectable in software settings.

• What display resolution is available for high-accuracy temperature readings?

  The 5-digit digital display supports resolutions down to 0.01 deg C for precise process feedback monitoring.

• What control output type is supplied on terminal connections for loop driving?

  The Q designation indicates a PNP/NPN voltage output configured primarily to trigger external Solid State Relays (SSR).

• How is preventive maintenance monitored on internal or external relays?

  The integrated Control Output ON/OFF Counter accumulates actuation cycles to signal output degradation limits.

• What software tool is used to configure flexible contact logic operations?

  Logic functions such as AND, OR, and delay timers are programmed using CX-Thermo Version 4.0 or higher.

• Can the process display alternate between PV and status information?

  Yes, PV/SV-status display switching can alternate between process values, setpoints, and RUN/STOP or alarm status states.

• How is electrical safety maintained at the rear terminal connections?

  The 500 suffix designates a pre-installed finger-safe terminal cover that guards exposed wiring terminations from accidental contact.
