Featuring Banner's exclusive Bi-Modal output
Standard OMNI-BEAM dc power blocks provide regulated low voltage
dc power to the sensor head and logic module (if one is used), with input
of 10 to 30V dc. There are two infinite-life outputs, one for the load and
the other for the alarm of the D.A.T.A. self-diagnostic system.
All models, except emitter-only types, have the unique Bi-Modal™
output design (US patent no. 4982107) that offers either sinking (NPN) or
sourcing (PNP) outputs, depending upon the polarity with which the two
dc supply leads are connected. Outputs are protected from overload,
shorted load, or low voltage conditions. Outputs automatically reset when
the cause of the problem is cleared. Problems are identified by the
D.A.T.A. light system.
All standard OMNI-BEAM power blocks are epoxy-encapsulated and
rated for -40 to +70 C (-40 to +158 F). They feature limit switch style
cross-hole design for front, back, or side mounting, plus a 30mm threaded
hub for swivel bracket or through-hole mounting. Models include
prewired cable or either style of quick-disconnect (QD) fitting. As-
sembled OMNI-BEAM Sensors are rated NEMA 1, 2, 3, 3S, 4, 12, and 13.

Models
The following three power blocks are for use with emitters only
(models OSBE and OSBEF). They contain no output circuitry.
The Bi-Modal output of
Standard OMNI-BEAM dc
power blocks is configured
for current sinking (NPN) by
connecting the BROWN
supply wire to +V dc, and
the BLUE wire to dc
common.
Outputs sink 100mA, maximum.
The Bi-Modal output of
Standard OMNI-BEAM dc
power blocks is configured
for current sourcing (PNP) by
connecting the BLUE supply
wire to +V dc, and the
BROWN wire to dc common.
Each output sources up to 100mA.

Specifications, Standard dc Power Blocks
Input:
maximum ripple.
Output:
alarm. Both are configured to either sink (NPN) or source (PNP),
depending upon the polarity of the power supply leads (see hookup
drawings). 100mA maximum continuous, overload and short circuit
protected (both outputs). Off-state leakage current less than 100 mi-
croamps. NOTES: Interface to TTL logic is not direct (contact factory).
When the load and the OMNI-BEAM do not share a common power
supply, load voltage must be the sensor supply voltage.
On-state Voltage Drop:
NPN outputs: <1.0V @10mA load, and <1.5V @100mA load.
PNP outputs: <1.0V @10mA load, and <1.5V @100mA load.
Hookup to PLC
Standard OMNI-BEAM dc
power blocks interface directly
to any type of programmable
logic controller or computer dc
input.
The current sinking configura-
tion (NPN) is shown here. For
the current sourcing configura-
tion, simply reverse the polarity
to the BROWN and BLUE
power supply wires.
Standard OMNI-BEAM emitter
sensor blocks (models OSBE
and OSBEF) simply require
supply voltage to operate.
Power blocks without output
circuitry are available for
powering emitters. However,
power blocks with output
circuitry may also be used to
power emitters (output circuitry
will go unused).
