PBT2
Input: 10 to 30V dc at less than 60mA (current draw
depends on scanner block used). 10% max. ripple.

normally open, one normally closed). 250mA
maximum, each output.
On state voltage drop: less than 1V dc
Off state leakage current: less than 10 microamps
PBT
Input: 44 to 52V dc at less than 60mA (current draw
depends on scanner block used). 10% max. ripple.

current to negative side of power supply). 250mA
maximum.
On state voltage drop: less than 1V dc
Off state leakage current: less than 10 microamps
PBP
Input: 10 to 30V dc at less than 60mA (current draw

MULTI-BEAM
DC Models
3- & 4-wire DC Power Blocks
PBT: the most commonly used dc power block. Its output is an NPN transistor, which sinks current to
the negative side of the power supply. The load is connected between the output and the positive side of
the power supply. Switching capacity is 250mA. There is no connection to terminal #4.
PBT48: exactly the same configuration as the PBT, but for 48V dc systems.
PBT2: provides two NPN outputs; one normally open, the other normally closed (equivalent to SPDT
relay). The normally closed output may be used when a load must de-energize when the MULTI-BEAM
operates (e.g. normally closed one-shot). NOTE: both outputs are open when dc power is removed.
PBP: similar to model PBT, except that it provides a PNP sourcing type output transistor. Sourcing
outputs are frequently required when interfacing to logic systems and programmable logic controllers
(PLCs) which require a positive source of dc voltage to generate an input condition. This type of interface
may also be accomplished by using PBT with a "pullup" resistor installed between terminals #1 and #3.
PBP48: a 48V dc version of model PBP.

MULTI-BEAM 3- & 4-wire power blocks provide regulated low voltage DC power to
the scanner block and logic module, and a solid state infinite-life switch (except in
emitter-only scanner blocks). Connections are made to heavy-duty screw terminals
which accept up to #14 gauge wire (no lugs are necessary). All power blocks are epoxy-
encapsulated and rated for -40 to +70 degrees C. Response times are determined by
the scanner block used, except that power blocks switching ac require up to 8.3
milliseconds to turn OFF in addition to the response time of the scanner block (plus
logic module time delays, if any).
Photo shows DC power block (left) and AC power block (right).
DC power blocks have gray housings; AC models are red.
