The mH-R8x8 or mH-R2x16 executive relays are the executive elements of the system that switch on the light circuits, any receivers in the building or control roller shutters or blinds. The load capacity of the elements is 8A in the case of the mH-R8x8 module or 16A in the case of the mH-R2x16 module. The mH-R8x8 module contains eight executive relays dedicated to controlling lighting and roller blinds, while the mH-R2x16 module contains two 16A relays dedicated to switching on power receivers (230V sockets). Relay modules are mounted in the switchgear and occupy a field of 2 modules (mH-R2x16) and 6 modules (mH-R8x8).
