Universal input allows simple setting of the input types (TC, RTD, DCV) or input measuring range. Various communication function are provided. Communication is possible with personal computer and programable logic controller. Function Specifications Signal Computation Function Measured input computation: Bias addition (00.0 to 00.0% of measured input range width.), firstorder lag filter (time constant off, to 0 s.) Contact input: Retains and displays maximum and minimum readings from measured variable. Resets the maximum and minimum readings. UM0 UM0E E indicates the model with expanded functions. Alarm Function Six different types of alarms are provided. If an alarm occurs, the alarm lamp indicates it. Four (one is optional) of the six can be used as relay contact outputs. Alarm types: high limit, low limit, Deenergized on high limit, Deenergized on low limit, Fault diagnosis, and FAIL output Setting ranges for process variable alarms: alarms; 00.0 to 00.0% of measured input range.
