All output relays are form C relays. Only one of the two states of the form C relay is connected to the MIFII output
terminal. For each output relay it is possible to select which state is preferred to have at the MIFII terminals, NC
(normally closed) or NO (normally open).
The figure shows the PCB of a MIFII relay, and the location of the jumpers used to select the configuration of each
output contact (NO or NC).
