Models

(Electromechanical relay output)
MULTI-BEAM 2-wire power block models 2PBA, 2PBB, and 2PBD contain a low voltage power supply which
utilizes a unique circuit to take a very small leakage current through the load and convert it to the dc power required
to run the scanner block and logic module. They also contain the solid-state switch that operates the load, and a
transient suppression circuit to prevent false operation from high voltage spikes on the incoming line. They are
completely solid-state for unlimited operating life.
Model 2PBR is a 4-wire power block which works with 2-wire scanner blocks and logic modules and offers an SPST
"hard" contact for switching heavy ac or dc loads. Model 2PBR2, also for use with 2-wire scanner blocks and logic
modules, uses a 3- or 4-wire hookup with SPDT "hard" contacts for switching heavy ac loads.
NOTE: MULTI-BEAM 2-wire ac power blocks are color-coded black.
Model 2PBR actually requires a 4-wire hookup and model 2PBR2 requires a 3- or 4-wire hookup,
even though they only work with 2-wire scanner blocks and logic modules. Both are powered by
120V ac across terminals #1 and 2. The 2PBR offers an SPST "hard" relay contact between
terminals #3 and 4. Model 2PBR2 is an SPDT version, with both contacts common to terminal
#1: terminal #3 is a normally open output, and terminal #4 is normally closed. These
configurations allow MULTI-BEAM sensors to directly interface large loads which draw more
than 3/4 amp like clutches, brakes, large contactors, and small motors. Model 2PBR can switch
both ac and dc loads; model 2PBR2 switches the ac line voltage to an ac load (see connection
diagrams). The 2PBR and 2PBR2 also eliminate the problem of voltage drop from series strings
of sensors operating low voltage ac loads. NOTE: install an appropriate value MOV (metal oxide
varistor) transient suppressor across the power block relay contacts when switching an ac
inductive device.
MULTI-BEAM 2-wire power blocks offer the ultimate in simplicity of sensor hookup. They wire
directly in series with an ac load, exactly like a limit switch. Response time of 2-wire power
blocks is determined by the scanner block, which is 10 milliseconds on/off. A built-in false pulse
protection circuit holds the output OFF for 100 milliseconds after power is initially applied to the
power block. 2-wire power blocks will operate from -40 to +70 degrees C (-40 to +158 degrees
F). Resistive loads must be less than 15,000 ohms and inductive loads must be greater than 1.2
watts (10 milliamps).
