Input: 105 to 130V ac, 50/60Hz.
Input: 210 to 250V ac, 50/60Hz.
Input: 22 to 28V ac, 50/60Hz.
Input: 11 to 13V ac, 50/60Hz.
NOTE: MULTI-BEAM dc power blocks cannot be wired in series.
PBD-2
These power blocks are the most commonly used for ac operation. As the typical hookup
shows, they are intended to switch the same ac voltage as is used to power the MULTI-BEAM.
However, the output of all four blocks is rated for 250V ac maximum, and all can switch a
voltage which is different than the supply as long as both ac circuits share a common neutral.
For example, a PBA could switch a 24V ac door chime, etc. Observe local codes when mixing
ac voltages in a wiring chamber. These blocks are designed to handle the inrush current of ac
inductive loads like motor starters and solenoids. The "holding current" specification of any
inductive load should not exceed the 750mA output rating. There is no minimum load
requirement. These power blocks will interface directly to all ac programmable controller
inputs. All contain built-in transient suppression to prevent false turn-on or damage from
inductive loads and line "spikes". Outputs of multiple power blocks may be wired in series or
parallel for "AND" and "OR" logic functions.
The current sinking output(s) of
MULTI-BEAM power block mod-
els PBT and PBT2 may be con-
nected directly to the primary input
(terminal #7) or the other inputs of
MICRO-AMP logic modules. The
following logic modules may be
used:
MA4-2 One shot
MA5 On/off delay
MA4G 4-input "AND"
MA4L Latch
Hookup to MAXI-AMP Logic Module
The current sinking output(s)
of MULTI-BEAM power
block models PBT and PBT-2
may be connected directly to
the input (terminal #5) or the
auxiliary input (terminal #3) of
any Banner B Series logic mod-
ule. The MULTI-BEAM is
powered by the MRB chassis
as shown. Additional logic
may be added on a longer chas-
sis. Banner PLUG-LOGIC
modules may also be used.
Most counters, totalizers, rate meters,
etc., including the battery-powered
LCD types, accept the NPN current
sinking output of MULTI-
BEAM power block mod-
els PBT and PBT2 as an
input. Counters which are
powered by ac line voltage
usually offer a low voltage
dc supply with enough ca-
pacity to power one
MULTI-BEAM (
≥ 10V dc
at ≥ 60mA).

The current sinking output(s) of MULTI-BEAM power block
models PBT and PBT2 may be connected directly to the input
of CL Series MAXI-AMP modules. A MAXI-AMP which is
powered by ac voltage offers a dc supply with enough
capacity to power one MULTI-BEAM sensor, as is shown in
this hookup diagram. When emitter/receiver pairs are used,
the emitter should be powered from a separate power source
(e.g.- using PBA-1, etc.)
Output: SPST solid-state switch for ac, 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 re-
sponse of the scanner block.
