Hookup Diagrams for AC Power Blocks
Model PBAQ is identical to model PBA (page 17) except that the solid-state output contact is
normally closed instead of normally open. It is used where it is necessary to have the load de-
energize when something is sensed (e.g.- one shot pulse to de-energize load). When no timing
logic is involved, model LM3 can program any power block for normally open or normally
closed operation via the light/dark operate jumper. NOTE: model PBAQ is not comaptible
with logic module models LM5 and LM5-14. For normally closed on-delay logic, use PBA
with LM5R and reverse the light/dark function.
NOTE: output switching capacity
is 3/4 amp maximum.
Input: 105 to 130V ac, 50/60Hz.
PBD-1
Input: 22 to 28V ac, 50/60Hz.

Input: 210 to 250V ac, 50/60Hz.

MULTI-BEAM emitter-only ac power blocks connect directly
across the ac line, as shown.
Emitter models: SBE, SBED, SBEX, SBEV, SBEXD, SBEF,
and SBEXF.
Hookup of an AC Emitter Hookup to a Simple AC Load
AC voltage is connected to terminals #1 and #2 to provide power to the MULTI-BEAM. The solid-state output
switch behaves as if there were a contact between terminals #3 and #4. L1 is most conveniently applied to
terminal #3 by jumpering terminals #1 and #3 inside the MULTI-BEAM.
The outputs of all five power block models are rated
for 250V ac maximum, and can switch an ac voltage
which is different from the supply as long as both ac
circuits share a common neutral. Observe local
wiring codes when mixing AC voltages in a common
wiring chamber.
Since the output switch is a solid-state device, con-
tact continuity cannot be checked by means of an
ohmeter, continuity tester, etc. To check the func-
tioning of the output switch, a load must be installed
and tested along with the MULTI-BEAM.
CAUTION: the output switch could be destroyed if
the load becomes a short circuit (i.e., if L1 and L2 are
connected directly across terminals #3 and #4).
NOTE: this hookup depicts the output switch as a
normally open contact. Model PBAQ actually has a
normally closed output switch.
Connections Functional Schematics
Input: 105 to 130V ac, 50/60Hz.
Output: SPST isolated solid-state switch; nor-
mally closed, 3/4 amp maximum (derated to 1/2
amp at 70 degrees C).
Maximum inrush: 10 amps for one second or 30
amps for one ac cycle (non repeating).
On-state voltage drop: less than 2.5V ac at full
load.
Off-state leakage current: less than 100
microamps.
Response: add 8.3 milliseconds to the off-time
response of the scanner block.
NOTE: the output of the PBAQ will not conduct
when power is removed from terminal #1 or 2.
These are power blocks for emitter scanner
blocks only (models SBE, SBED, SBEX, SBEV,
SBEXD, SBEF, SBEXF). Emitter assemblies
do not require logic modules.
