What is a substitute product for MKF-P Flicker Relays?
1.H3CR-A Solid-sate Timers. 8-pin H3CR-A8 cannot be used because they do not support a flicker OFF start, which is the operating mode of MKF-P.
Therefore 11-pin P2CF-11 Surface Mounting Sockets are required, as well as new wiring. Interconnect terminals 2 and 6. Use a power-ON start in mode B, with a flicker OFF start.
2.By setting equivalent ON and OFF times for H3CR-F8 Twin Timers with flicker OFF start, the functionality can be replicated.
It is recommended that the socket is changed to P2CF-08. If you continue to use 8PF(A) Sockets, they must be used with Y92F-42 Adaptors.
The terminal arrangements of external connectors are not compatible.
