INPUT: 10 to 30V dc, 20mA, exclusive of load cur-

rent; 10% maximum ripple.

OUTPUT: one open-collector NPN (current sinking)

and one open-collector PNP (current sourcing) transis-

tor. 250mA continuous, short-circuit and reverse po-

larity protected (both outputs).

ON-STATE VOLTAGE DROP:

PNP output: less than 1 volt at 10mA and less than 2

volts at 250mA.

NPN output: less than 200 millivolts at 10mA and less

than 1 volt at 250mA.

OFF-STATE LEAKAGE CURRENT: less than 10

microamps.

Power block RPBT is the one most often used in low voltage dc applications. There are two

solid state output switches (transistors), each rated at 1/4 amp. The NPN output at terminal #3

of the wiring base sinks current to the negative side of the power supply. The PNP output at

terminal #4 sources current to the load from the positive side of the power supply. Both outputs

may be used simultaneously. Response time of a MAXI-BEAM which uses model RPBT is

the response time which is programmed at the sensor head (plus logic delays, if any). Model

RPBT-1 is the dc power block to use with model RSBE, RSBESR, and RSBEF emitter sensor

heads. The RPBT-1 has no switching elements.

MAXI-BEAM power blocks provide regulated low voltage dc power to the sensor head and

logic module (if one is used), and all power blocks (except emitter-only types) contain an

output switch for interfacing to loads or to control circuitry.

Power blocks plug into the model RWB4 wiring base which has heavy-duty screw

terminals that accept up to #12 gauge wire (no lugs are necessary). The RWB4 wiring base

is necessary for all MAXI-BEAM sensor assemblies (except sensors using the RPBTLM

power block), and must be purchased separately.

All power blocks, except the emitter-only types, include status LEDs which continuously

indicate the state of the output circuit and input power. MAXI-BEAM power blocks are

epoxy-encapsulated and rated for -40 to +70 degrees C (except models RPBR and RPBR2).

All MAXI-BEAMs have circuitry to prevent false closure of the output on power-up.
