Memory & latching relays MR-41, MR-42
! Latching relays, controlled by buttons from several locations can replace three way switches or cross bar switches
thanks to control by buttons (unlimited number, connected in parallel by 2 wires), installation gets more transparent
and faster for mounting.
! Relays MR-41/UNI, MR-42/UNI memorize its last state even after supply failure. During the failure relay will turn off and
after re-energizing will automatically turns on.
! MR-41
- output contact: 1x changeover / SPDT 16 A
! MR-42
- options - 2x parallel contacts or the other relay is latching
- function selected via external jumper between B1 - B2
- output contact: 2x changeover /SPDT 16 A
