RKI-500
Purpose
The relay of control of isolation of RKI-500 is intended for control of resistance of isolation in single-phase and three-phase networks of an alternating voltage to 450 V with a frequency of 50 Hz with the isolated neutral.
At deterioration of isolation the internal system of the sound and light notification joins, and contacts of the executive relay switch.

Design of system
The RKI-500 block is executed in the case for installation on a DIN lath.
The RKI-500 block is executed in the case for installation on a DIN lath.
– On the forward panel of the block there are LED indicators "NETWORK", "ACCIDENT" and the buttons "TEST", "DUMPING", "Shutdown of a Sound Signal".
– In the top and lower part of the block there are terminal blocks for connection of power supply, a controlled network and other control units and alarm systems.
– Power supply of the relay can directly be carried out from a controlled network or from not stabilized source of constant voltage of =24 V, =12 V. Power-supply circuits, measurement and contact of the output relay galvanic are divided.
