Compact and intelligent Ramp/Soak controllers

The E5_C-T Ramp/Soak temperature controllers expands the E5_C family to handle process applications. Capable of handling up to 6 event inputs and up to 4 auxiliary output all in a compact 60 mm (depth) housing, makes this controller series one of Omron's most powerful and versatile temperature controllers.


  • Set up to 8 programs with 32 segments totaling 256 program segments simply via CX-Thermo software.
  • The three-level display is visible simultaneously so each process status can be easily identified.
  • "Segement Jump" allows users to easily move directly to the specified segment reducing programming time and increase production throughput.

Temperature profiles


Process Control according to your needs

Applying less stress to valuable objects due to reduced temperature overshot (step response) and precise regulation in terms of disturbances, is our recipe for best processing results providing the added value for machine/object. Ramping and soaking can be fluently executed without the need for adjusting parameters manually. Even if there are changing process characteristics, the powerful auto-tuning quickly leads the user to a stable operation, overtaking PID settings automatically.

Setting-up temperature profiles is made easy by using CX-Thermo Software which is applicable for the whole E5_C Platform. This tool helps to visualize and track the process in diagrams or log data on an external host with Windows operation system.

LCD display


"JUMBO" LCD display for best visibility

Providing the relevant PV/SV values on the largest display in its class on the Global Market*, with outstanding visibility and contrast. Even under severe ambient lighting conditions E5_C can be read from a far distance. Due to its modern ergonomic design (IF Design award) the E5_C can optically be integrated into every panel. Additional information about the executed program and operating segment can be seen at a glance.

Easy Set-up


Quick commissioning of machines

The E5_C series can be easily connected, set-up and operated in only a few steps using the instrument’s 5 front keys. The CX-Thermo software and useful navigation assistant for intuitive settings allows for a very quick parameter setting, easier device adjustment and simpler maintenance.

Precise control

Rely on our patented 2-PID

For many years our goal is to assure best regulation performance in temperature control. Following the patented 2-PID algorithm, integrated in almost every Omron controller, the same recipe can be found in the “T”-Programmer family. Combined with a unique control loop time of 50 ms and 0,1 °C of resolution, E5_C-T is the best partner for saving time in terms of quick disturbance response while keeping high precision in regulation of temperature. As the design of machines is continuously moving into high speed requirements, our controllers have already adapted to these tendencies.


Useful functions


Standard Alarms

  • You can output an alarm when the deviation, process value, set point, or manipulated value reaches a specified value.
  • You can also output alarms for the PV rate of change and for loop burnouts.
  • If necessary, a more comprehensive alarm function can be achieved by setting a standby sequence, alarm hysteresis, auxiliary output close in alarm/open in alarm, alarm latch, alarm ON delay, and alarm OFF delay.

HB and HS Alarms

  • With models with the optional HB and HS alarms, you can detect heater burnout and heater short alarms based on CT inputs.

Integrated Alarm

  • You can output an integrated alarm if a standard alarm, HB alarm, or HS alarm turns ON.

Event Inputs

With any model that supports event inputs, you can use external contact or transistor inputs to achieve any of the following functions: You can control the following:

  • Changing programs (changing program number, 8 max.), changing between run and reset status, changing between automatic and manual operation, inverting direct/reverse operation, changing between program SP and fixed SP, 100% AT execute/cancel, 40% AT execute/cancel, 100% AT execute/cancel for all PID sets, 40% AT execute/cancel for all PID sets, setting change enable/disable, communications write enable/disable, canceling the alarm latch, hold/clear hold, advance, and wait enable/disable.

Communications Functions

  • With any E5_C-T model that supports communications, you can use CompoWay/F, Modbus-RTU,*1 programless, and component communications. Additionally Profibus, Profinet and Modbus TCP protocols are supported.

*1 Modbus is a registered trademark of Schneider Electric.

Transfer Output

  • With any model that provides a transfer output, you can output the set point, process value, manipulated variable, or other values as a 4 to 20-mA or 1 to 5-V transfer output.

Program Patterns : Programs: 8 patterns max., Segments: 32 max. per program

  • Program initial set point: Segment 0 set point, present value (PV), or fixed SP
  • Program start time: Standby operation (delay) can be set.
  • Repeating and linking programs are also possible.

Controlling the Program

  • Run (program operation started)/Reset (program operation stopped)
  • Advancing the segment holding
  • Waiting to advance to the next segment
  • Jumping to segments with a key operation

Program Status Outputs

  • Time signals
  • ON output in run status
  • ON output at program end
  • Stage outputs (one-pulse output at start of each segment)

Adjusting PID Constants

  • You can easily set the optimum PID constants for the current PID set or for all PID sets by performing AT (auto-tuning) with the limit cycle method.
  • You can also add RT (robust tuning) to give priority to controlling stability.
