RKI-35
Purpose
The relay of control of isolation of RKI-35 is intended for control of resistance of isolation in single-phase and three-phase alternating current mains 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.
Technical characteristic
Design of system
The RKI-35 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 connections, controlled network and other control units and alarm systems.
Power supply of the relay can directly be carried out from the controllable networks ~ 220 Century. Power-supply circuits (A1, A2), measurement (N, PE) and contacts the output relay are galvanic divided.
