MSD Dual Delay Timer
PN 7563
Parts Included:
1 - Dual Timer Delay
WARNING: Before installing the MSD Timer, disconnect the battery cables. When dis-
connecting the battery cables, always remove the Negative (-) cable first
and install it last.
The Dual Delay Timer allows you to activate two different circuits based on time (Channel 1
and Channel 2). Each Channel can be used to activate (supply a ground source) or deactivate
(remove the ground) at a programmed time. The time is adjustable down to 0.01-second
increments.
Note: To control devices that require over 2 amps, a relay will be required. MSD offers a
SPDT 30 Amp/12 Volt DC as PN 8961 or a DPDT 30 Amp/12 Volt DC as PN 8960.
