5.4 12V DC Output
The programmable 12V DC output provides a nominal 12 Volts at up to 40mA of direct current and is available at
the rear of the unit. The 12V DC output can be used to provide confirmation to a central controller, to control
another power distribution product, to drive LEDs, or to provide feedback to the previous SEQ in a cascaded
chain. Please see the applications section for full details on setting up an expanded system. There are three
menu items to control the 12V DC output: one to select the mode of operation, and two to set the delay times.
The two delay times are only applicable when option A, B, or C is selected for 12V DC Output. There is additional
information on the 12V DC output in Sections 3.2.3 and 3.2.4. If the DC output is not used it can be left at any
setting.

A Output synchronized with Bank A

C Output synchronized with Bank C
LED Flashes while powering Up and Down to drive LEDs
Cascade Provide feedback to the previous cascaded unit
12V Delay On 0 – 40 Seconds Set power-up delay time when set to A, B, or C. This delay time
begins with the same internal trigger as the bank selected in the
previous item. For example, if you wanted a fourth bank to power
on first and off last, you should select A as the 12V DC Output
and set this delay time to be shorter than the delay that you set
for Main Bank A On (the 12V Delay On can be set to zero in this
case); or if you wanted a fourth bank to power on last and off first,
you should select C as the 12V DC Output and set this delay time
to be longer than the delay that you set for Main Bank C On.
12V Delay Off 0 – 40 Seconds Set power-down delay time when set to A, B, or C. This delay
time begins with the same internal trigger as the bank selected in
12V DC Output. For example, if you wanted a fourth bank to
power on first and off last, you should select A as the 12V dc
Output and set this delay time to be longer than the delay that you
set for Main Bank A Off; or if you wanted a fourth bank to power
on last and off first, you should select C as the 12V DC Output
and set this delay time to be shorter than the delay that you set
for Main Bank C Off (the 12V Delay Off can be set to zero in this
case).
