Use of the interface component

The REG-FA position indicator interface adapts the position indicator of the contact bank of a tap changer with AWZ code to the REGSys voltage regulator system.

An external auxiliary voltage feeds the contact bank; it is to be connected to the “AWZ U+” and “AWZ GND” terminals of the REG-FA. Switch contacts issue the signals A1, A2, A3 or A10, A20, A30 to the REG-FA; these are converted by the code converter into BCD code. The outputs trigger the BCD inputs of the REG-D and 6 relay contacts provide the BCD code for further use.

• Up to 39 switching positions are translated into BCD code
• The cables between the tap changer and REG-FA can be up to 100 m in length
• Fault suppression through optical separation of inputs
• Relay contacts with AC 250 V 2 A, DC 220 V 150 W
• Large range of auxiliary voltages from the power supply
