  • For remote measurement of physical quantities. The input signal may be direct voltage or current or change of resistance.
  • It enables signalling that two limits have been exceeded – either only on a display or by means of a relay with switch-over contact
  • In design for measurement of current signals (504 xx2 xxx), the device is equipped with a source of voltage for supply of converter; the source has current limitation approx. 30 mA and its output is brought to terminal 1;
  • In design for measurement of resistance signals (504 xx3 xxx), the output of the source of measuring current approx. 0.5 mA is brought out on terminal 1;
  • In design with relay signalling, the device may also be used as proportional discontinuous regulator.
  • The devices are rated products pursuant to the Act No. 22/1997 Coll. and the Declaration of Conformity EC-504000 is issued for them.
