Hookup Diagrams for DC Power Blocks
DC Models
These are power blocks for emitter scanner blocks only (models SBE, SBED, SBEX, SBEV, SBEXD, SBEF, SBEXF). Emitter assemblies do
not require logic modules.
When using power blocks with current sinking (NPN)
outputs, simple loads connect between the power block
output (terminal #3) and the positive supply (terminal
#1).
MULTI-BEAM emitter-only scanner blocks use dc power
block models PBT-1 or PBT48-1. These power blocks
connect directly across the dc supply, as shown.
Any number of MULTI-BEAMs may be connected in parallel to one load to create "LIGHT-OR" (light operate
mode) or "DARK-OR" (dark operate mode) multiple sensor logic. In most situations, MULTI-BEAM dc power
blocks cannot wire in series. However, addition of an interposing relay with a normally closed contact or a Banner
logic module will permit "AND" logic with a parallel sensor array.

Output capacity: 250mA
maximum, each output.
When using power blocks with current sourcing (PNP)
outputs, simple loads connect between the power block
output (terminal #3) and dc common (terminal #2).
A logic zero (0 volts dc) is applied to the gate input
when the MULTI-BEAM output is energized. When
de-energized, a logic one is applied. The logic supply
must be common to the MULTI-BEAM supply nega-
tive.
Use power blocks with NPN
outputs to interface to PLCs and
other logic devices requiring a
current sink at the inputs. Con-
nect the output of the power
block (terminal #3) to any input
of the PLC. Also connect the
negative of the MULTI-BEAM
power supply (terminal #2) to
the negative of the PLC power
supply.
