These are power blocks for emitter scanner blocks only (models SBE, SBED, SBEX, SBEV, SBEXD, SBEF, SBEXF). Emitter assemblies do
not require logic modules.
MULTI-BEAM
PBT-1
Input: 10 to 30V dc at less than 60mA (current draw
depends on scanner block used). 10% max. ripple.
PBT48-1
Hookup Diagrams for DC Power Blocks
Input: 44 to 52V dc at less than 60mA (current draw
depends on scanner block used). 10% max. ripple.
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).
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.

Parallel Hookup to a Common Load
Hookup to a Programmable Controller
requiring a current sink
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.

Hookup to a Programmable Controller
requiring a current source
Use power blocks with PNP out-
puts to interface to PLCs and
other logic devices requiring a
current source 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 nega-
tive of the PLC power supply.

Functional Schematic
Hookup of DC Emitter
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.
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.
