DR130

You can freely set a wide range of inputs including DC voltage, thermocouple, RTD, and contact signals, by a simple key operation. A lineup of high cost performance models designed exclusively for voltage, thermocouple and contact inputs is also available. In addition, you can select power monitor input options that enable you to measure RMS values of AC voltage and current, active power, apparent power, reactive power, frequency, power factor and phase angle (for both single phase and 3-phase applications).

• Mutual channel isolation. Reliable high withstand voltage and noise immunity
  Each channel of the input circuit is isolated from the others by high breakdown voltage solid state relays*¹ . As a result, the common mode rejection voltage is 250 V AC*² rms, and the withstand voltage is 1,500 V AC*² (1 minute). Excellent noise rejection is ensured by the built-in power line noise rejection filter employing an integrating type A/D converter, low-pass filter, and moving average digital filter*³.
  
  *1: RTD inputs share a common line within the same module.
  *2: Depends on input module types.
  *3: The shortest measurement interval varies depending upon the integration mode and the low-pass filter mode.
