14.4 Option board impulse //
This option board does not require any software programming.
It allows to add a minute, ½ minute, second or SR2-59 impulse output or TBT
24V DC 1A power supply. See page 36, the menu of the time outputs to set
this output. Use the two Power DIP switches to select internal (24V) or
external power (from 20 to 50 V).
The jumper allows to adjust the maximum amperage of the output.
Caution: the maximum amperage will depend on the version of SIGMA master
clock.
