The Omron E5CN-C2MT-500 AC100-240, also cataloged as the E5CN-C2MT-500 Temperature Controller, operates as a dedicated hardware component for closed-loop thermal process management and linear current regulation within industrial control networks.

Model Suffix Engineering Structure

• E5CN: 1/16 DIN compact digital temperature controller base architecture.
• C: Linear current output control method (4 to 20 mA DC or 0 to 20 mA DC).
• 2: Two auxiliary alarm contact outputs integrated on main board.
• M: Option unit mountable platform design.
• T: Thermocouple and platinum resistance thermometer universal input compatibility.
• 500: Terminal cover included with finger-safe protection rating.
• AC100-240: Line operating power supply range (100 to 240 VAC at 50/60 Hz).

Product Technical Parameters

Deterministic Network Bus Architecture

When networked alongside PLC logic racks, the controller utilizes internal analog conversion channels to process temperature sensor inputs without impacting backplane bus communication velocity across connected PLC networks. Internal parameter retention retains firmware flash compatibility, preventing configuration loss during transient power dips while delivering deterministic control loop execution.

Scope of Delivery

• 1 x Omron E5CN-C2MT-500 AC100-240 Temperature Controller
• 1 x Panel mounting adapter bracket
• 1 x Terminal cover set (500 series specification)
• 1 x Instruction documentation manual

Enclosure Mounting & Wiring Protocol

• Cut a standard 45 x 45 mm square hole in the enclosure door panel and insert the controller unit from the front side.
• Slide the mounting adapter frame onto the rear of the housing until the locking latches secure the front bezel flush against the panel surface.
• Connect line voltage wires (100 to 240 VAC) to designated supply terminals using M3 screw torque limits between 0.5 and 0.6 N m.
• Attach thermocouple lead wires using compensation cables matching the specific thermocouple type (K, J, T, etc.) directly to the designated input terminals.
• Route the 4-20 mA control current output cable through shielded twisted-pair wire, keeping it isolated from heavy AC motor lines.

Technical Support FAQ

• Can the 4-20 mA current output be reconfigured for 0-20 mA DC control operation?

  Yes, the analog current output range can be adjusted between 4 to 20 mA DC and 0 to 20 mA DC in the advanced setup parameter menu.

• What thermocouple sensor types are natively supported by the E5CN-C2MT-500 input circuit?

  The universal input hardware supports B, E, J, K, L, N, R, S, T, U, W, and PLII thermocouple sensor types.

• Is cold junction compensation performed internally for thermocouple sensors?

  Yes, internal ambient temperature sensing circuits provide automatic cold junction compensation for all connected thermocouple inputs.

• How does the unit preserve setup parameters during total power loss?

  All user settings, set points, and calibration values are written to non-volatile EEPROM memory with unlimited read-write retention cycles.

• Can the auxiliary alarm outputs be configured as normally closed contacts?

  Yes, auxiliary relay output contacts 1 and 2 can be set to operate as normally open or normally closed via internal alarm configuration logic.

• Is hot-swapping permitted while the controller panel is energized?

  No, main AC supply voltage must be disconnected before removing the internal module chassis or altering rear terminal screw connections.

• What measurement accuracy is achieved across supported input temperature scales?

  The controller maintains an input measurement accuracy of +/- 0.1% of indicated value plus 1 digit under nominal operating conditions.

• How is key protection enabled to lock setpoint values on the front display?

  Parameter protection levels can be adjusted in the software utility menu to prevent local front-panel modification of critical thermal control loops.
