The MPW‑61 high voltage relay's module allows for actuaction of fire protection devices powered from 230V eg. ventilators, fire dampers, smoke exhaust dampers. The module has:

-  2 programmable relays PK1 and PK2 high voltage type (5 A/ 230 V),
-  2 supervised programmable LK1 and LK2 (24 V) monitoring lines.

Output relays lines PK1 and PK2 are additionally protected by a fuse with a nominal value of 6.3 A / 250 V.
