When constructing a failsafe circuit using ondelay timers only
*2 Since YB0 turns ON and OFF alternatively at 0.5 second
intervals, use a contactless output module (a transistor is used in
the above example).
*3 If an offdelay timer (especially miniature timer) is not available,
construct the failsafe circuit using an ondelay timer shown on the
next page.
*1 Use a solid state relay for the M1 relay.
