• The M2 Series has the most complete range of models.

  The Compact M2 Series Plug-in Signal Conditioners have the most complete range of models. Many of the models in this wide range can be delivered quickly and are approved by various certification agencies.

  Thanks to thorough part control, many models in this signal conditioner series do not exceed the regulation values for specific hazardous substances restricted by the RoHS Directive, so they can be used with peace of mind.

  

• Compact, plug-in socket mounted

  

  (click to enlarge image)

  The space-saving plug-in structure allows for inspection and replacement without having to disconnect any wiring.
  The base socket and signal conditioner body are securely fastened with mounting screws, so there is no risk of loosening or detachment.

• Isolation and power supply

  Three-port isolation
  Dielectric strength: 2000 V AC @ 1 min.

  AC power supply: 85-264 V AC, 100 – 240 V AC
  DC power supply: 24 V DC, 11 – 27 V DC, 110 V DC

  * Specifications may vary depending on the model. For details, see the datasheet.
  

• High-density mounting・standard type

  Models in the Compact M2 Series Plug-in Signal Conditioners feature a slim, space-saving structure that is only 23 mm wide. Sixteen units can easily be accommodated in a 19-inch rack, and use of the dedicated installation base makes installation even more convenient.

  

• Ideal for loop checks and maintenance when instant visibility is required.

  With its high brightness and contrast, the OEL display provides excellent visibility and is ideal for tasks where mistakes must be avoided, such as loop checks and signal checks during maintenance.
  The display can be configured to remain on continuously or to turn on when a button is touched.

  

• Multi-function display

  Multiple values are displayed in two rows.

  Both the upper and lower rows can display up to six digits. Displayed contents can be freely assigned to inputs or outputs, while measured values, engineering unit values, scaled values, percentage values, and units can be configured individually.

  

  Display settings can also be configured easily.

  Just switch to display setting mode and select the content to display for the upper and lower rows.

  

  No need to refer to the instruction manual.

  Although it is normally necessary to check the corresponding number of a setting in the instruction manual, with the M2E Series, settings are displayed using text, eliminating the need to look up numbers.

  

  Single display

  If you only need to display one item or want to display it in large text, you can select single display.

  

• Settings can also be configured via PC.

  This feature is useful when configuring multiple settings with similar specifications or for saving settings.

  *1. Model M2EACFG is the alarm output type. *2. An optional configurator connection cable (Model: COP-US) is required.

Signal conditioners configurable via PC
Specifications will be configured as requested free-of-charge when shipped from the factory.

• 

  PC programmable

  With these signal conditioners, specifications can be configured using a PC. This allows for use in a wider range of applications, as setting ranges are larger and more tailored specifications can be configured.
  Some models, such as those in the M2E Series, allow for settings to be configured just using the buttons on the front panel and without using a PC.

Unique signal conditioners

• Universal Transmitter

  
  Select from among five types of inputs, including DC current, voltage, thermocouple, RTD and potentiometer. Models with Modbus outputs are also available. UNIVERSAL TRANSMITTER (PC programmable)M2XU UNIVERSAL TRANSMITTER (PC programmable; Modbus-RTU communication) M2XUM

  CT Transmitter

  
  This converts AC signals to standard instrumentation signals. Small base sockets are prone to contact welding caused by factors such as motor inrush currents, so these models are designed so that input signals bypass the base socket. CT TRANSMITTER (average sensing, RMS calibrated) M2CA CT TRANSMITTER (RMS sensing) M2CE
  

  Signal Transmitter, ultra-high speed response 30 µsec.

  
  This transmitter has three characteristics essential for charge-discharge testers: high conversion accuracy, ultra-low temperature drift, and ultra-fast response. SIGNAL TRANSMITTER (high-accuracy, ultra-high speed response 30 µsec.) M2VF3
