• 3: 3 auxiliary relay outputs sharing a single common terminal connection
• A: Operating line power supply rated for 100 to 240 VAC input
• 5: Wiring terminal configuration utilizing M3 screw terminals with protective cover
• M: Universal analog input processing (thermocouple, RTD, analog voltage, linear current)

Physical & Electrical Hardware Parameters

Deterministic Network & Controller Memory Integrity

The controller maintains high-speed 50-ms sampling cycles to interface directly with programmable logic controllers across RS-485 network buses. Internal flash memory firmware flash compatibility guarantees parameter storage persistence without battery backup during power loss events. Galvanic isolation between power circuits, analog sensor input channels, and linear output stages prevents ground loop interference across high-density I/O panel installations.

Scope of Delivery & Package Contents

• 1 x Omron E5CC-CX3A5M-004 Digital Temperature Controller
• 1 x Pre-fitted Rear Screw Terminal Protective Cover
• 2 x Panel Mounting Adapter Brackets
• 1 x Instruction Manual & Panel Cutout Sheet

Cabinet Installation & Field Wiring Guidelines

• Panel Cutout & Mounting Punch a standard 45 x 45 mm DIN cutout in the enclosure door. Insert the controller through the panel cutout and slide the mounting brackets along the housing until secured flush against the panel surface.
• Terminal Screw Tightening Terminate field conductors with insulated spade or ring lugs. Torque rear panel M3 terminal screws to a range between 0.43 and 0.58 N.m to ensure tight electrical contact without stripping threads.
• Signal & Communication Shielding Route sensor inputs and RS-485 communication lines separately from AC power lines and inverter output leads. Ground the RS-485 shield wire at a single point to minimize electrical noise coupling.

Frequently Asked Questions

• What primary control signal is driven by the CX output configuration?

  The CX designation provides a linear DC current output configurable for 4-20 mA DC or 0-20 mA DC into a maximum load impedance of 500 ohms.

• What communication protocols run over the built-in RS-485 port?

  The unit supports Modbus-RTU and standard Omron CompoWay/F serial protocols over a 2-wire half-duplex RS-485 bus interface.

• How are the 3 auxiliary outputs wired electrically?

  The 3 auxiliary relay outputs operate as SPST-NO contact sets sharing a single internal common line, rated for 250 VAC at 2 A resistive load.

• What types of field sensors can be connected to the universal input?

  The universal input accepts standard thermocouples, Pt100/JPt100 RTDs, 4-20 mA DC current loops, and 0-10 VDC analog voltage signals.

• What function do the 2 event inputs serve on option 004?

  The event inputs accept external voltage-free contact signals to remotely switch set points, execute RUN/STOP states, or initiate auto-tuning.

• Is a transfer output included on the E5CC-CX3A5M-004 variant?

  Yes, the 004 option code includes a linear 4-20 mA DC analog transfer output for process value or set point retransmission to external recorders.

• What is the sampling rate of the internal sensor processing circuit?

  The analog processing engine samples connected sensor inputs continuously at a high-speed update cycle time of 50 ms.

• Can the controller be wired using standard fork crimp terminals?

  Yes, the terminal block features M3 screw connections protected by a snap-on cover designed to fit standard fork or ring crimp lugs.
