  • universal input for PT 100, thermo couple, mA, V
  • inputs selectable via software modi
  • freely adjustable control and display area
  • self-optimization of the PID control parameters
  • input for external given value
  • 2 internally given values switchable via keys or binary input
  • 2 (URE 422) relay outputs for control or limit values
  • analog output with galvanic separation for the control variable Y, the given value W or the actual value X (option)
  • outputs switchable via software modi for steady, two-point, three-point or three-point step action
