RKI-50
Purpose
РThe relay of control of isolation of RKI-50 is intended for control of resistance of isolation in single-phase and three-phase networks variable тока 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-50 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 power connection, a controlled network and other control units and the alarm system.
– Power supply of the relay can directly be carried out from a controlled network ~ 220 В or from not stabilized source of constant voltage of =24 V, =12 V. Chains of power supply, measurement and contact of the output relay are galvanic divided
