Product Information

• Product information
  • The devices of the ACT20P-UI-2RCO-XX-x family record current, voltage, potentiometer and temperature sensor signals (mA, A, mV, V, potentiometer, RTD and TC). They have two independent relay outputs which emit an alarm when levels exceed or fall below pre-set limits. Properties Configuration and diagnosis with the FDT/DTM software “WI-Manager”. Manual configuration on the device is performed via the LED display by means of operating buttons and rotary encoders. The dual-channel trip amplifier enables various alarm functions: window alarm, alarm delay, wire break detection, hysteresis and upper / lower limit alarm. The active or passive signal inputs for RTD, TC, potentiometer, voltage and current are fully galvanically isolated. Remote diagnosis: reporting of errors (e.g. cable breaks) via status relay. Operational status and relay status indicated by front panel LEDs. Galvanic 4-way isolation between input, output and supply.
