MULTI-BEAM
Hookup Diagrams for AC Power Blocks (continued)
Hookup in Parallel with other MULTI-BEAMs
Any number of 3- & 4-wire
MULTI-BEAM power block
outputs may be connected in
parallel to a load. Parallel sen-
sor connection is usually used to
yield "OR" logic (i.e., if an event
occurs at any sensor, the load is
energized).The total off-state
leakage current through the load
is the sum of the leakage current
of the individual power blocks.
However, the maximum leak-
age current of MULTI-BEAM
3- & 4-wire ac power blocks is
only 100 microamps. As a re-
sult, installation of an artificial
load resistor in parallel with the
load is necessary only for large
numbers of sensors wired in par-
allel to a light load.
Interfacing to a PLC I/O is direct with MULTI-BEAM 3- & 4-wire ac power
blocks. All models have less than 100 microamps (0.1 milliamp) of off-state
leakage current. If you have a question on hookup to a particular brand of
PLC, contact the Banner Applications Department during normal business
hours.
Hookup to a Programmable Logic Controller (PLC)
Hookup in Parallel with Contacts or Switches
Any number of "hard" contacts
may be wired in parallel with
one or more MULTI-BEAM
3- & 4-wire power blocks. All
models have less than 100
microamps (0.1 milliamp) of
off-state leakage current. The
load operates when either the
contacts close or the MULTI-
BEAM output is energized.

Hookup to a Counter
Power block models PBO and PBOB are
designed to power the MULTI-BEAM with
ac voltage and to permit the sensor output to
interface with low voltage
dc circuits and devices. A
common situation involves
inputing to battery-powered
LCD totalizers, rate meters,
etc. The output switch is the
transistor of an optical cou-
pler, which may be connected
to switch dc common to the
count input. Polarity must
be observed.
MULTI-BEAM 3- & 4-wire ac power blocks may be wired in series with
each other for the "AND" logic function. The total voltage drop across the
series will be the sum of the individual voltage drops across each power
block (approximately 3 volts per block). With most loads, 10 or more
power blocks may be wired in series.
Terminals #3 and #4 of
MULTI-BEAM 3- & 4-wire
power blocks may be con-
nected in series with one or
more "hard" contacts. The
load operates only when all
contacts are closed and the
MULTI-BEAM output is en-
ergized.
