ripple.|||| ## Overview A Banner MULTI-BEAM Sensor is a compact modular self-contained photoelectric switch consisting of three components: a scanner block, a power block, and a logic module. The scanner block comprises the housing for the sensor and contains a complete modulated photoelectric amplifier, the emitter and receiver optoelements and lenses, and space for the other modules. The power block module provides the interface between the scanner block and the external circuit. It contains a power supply for the MULTI-BEAM plus a switching device (except in emitter-only power blocks) to interface the sensor to the circuit to be controlled. The logic module interconnects the power block and scanner block both electrically and mechanically. It provides the desired timing logic function (if any) plus the ability to program the output for either light- or dark-operate. The emitters of MULTI-BEAM opposed mode emitter/receiver pairs do not require a logic module. Emitter scanner blocks are supplied with a bladepin to interconnect the scanner block and power block. Power block and logic modules are purchased separately. This modular design, with fieldreplaceable power block and logic modules, permits a large variety of sensor configurations, resulting in exactly the right sensor for any photoelectric application. Original Document 03499 Rev. C 8 July 2022 03499 MULTI-BEAM 3- and 4-wire DC Power Block Modules ## Power Block Modules MULTI-BEAM 3- and 4-wire DC power block modules provide regulated low voltage DC to power the scanner block module and logic module in MULTIBEAM modular photoelectric sensors. They also contain a solid-state infinite-life switch (except in emitter-only scanner blocks) for switching external circuitry. Open-collector output transistors switch up to 250 mA maximum - see Specifications in Models on page 1. On-state voltage drop is less than 1 V DC. Off-state leakage current is less than 10 microamps. 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 °C to +70 °C (–40 °F to +158 °F). Response times are determined by the scanner block used. Models are available to operate from either 10 V DC to 30 V DC, or 44 V DC to 52 V DC. All 3- and 4-wire DC power block modules are color-coded gray. If you are unable to find the power block for your interface, contact Banner Engineering. ## Wiring Descriptions and Diagrams ## PBT, PBT48 PBT is the most commonly used DC power block. Its output is an NPN transistor, which sends current to the negative side of the power supply. The load is connected between the output and the positive side of the power supply. The switching capacity is 250 mA. There is no connection to terminal #4. PBT48 has exactly the same configuration as the PBT, but for 48 V DC systems. **==> picture [96 x 7] intentionally omitted <==** **----- Start of picture text -----**

## PBT2 PBT2 provides two NPN outputs: one normally open, and one normally closed (equivalent to SPDT relay). The normally closed output may be used when a load must de-energize when the MULTI-BEAM operates (for example, normally closed one-shot). Note: Both outputs are open when DC power is removed.

## PBP, PBP48 PBP is similar to model PBT, except that it provides a PNP type output transistor. PNP 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 pull-up resistor installed between transistors #1 and #3. PBP48 has exactly the same configuration as the PBP, but for 48 V DC systems. P/N 03499 Rev.

When using power blocks with current PNP outputs, simple loads connect between the power block output (terminal #3) and DC common (terminal #2). Any number of MULTI-BEAMs may be connected in parallel to one load to create LIGHT-OR (light operate mode) or DARK-OR (dark operate mode) multiple sensor logic. In most situations, MULTI-BEAM DC power blocks cannot wire in series. However, addition of an interposing relay with a normally closed contact or a Banner logic module will permit AND logic with a parallel sensor array. Note: MULTI-BEAM DC power blocks cannot be wired in series. **==> picture [426 x 144] intentionally omitted <==** **----- Start of picture text -----**

A logic zero (0 V DC) is applied to the gate input when the MULTI-BEAM output is energized. When de-energized, a logic one is applied. The logic supply must be common to the MULTI-BEAM supply negative. MULTI-BEAM emitter-only scanner blocks use DC power block models PBT-1 or PBT48-1. These power blocks connect directly across the DC supply, as shown. Emitter models: SBE, SBED, SBEX, SBEV, SBEXD, SBEF. The NPN 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 shown in this wiring diagram. When emitter/receiver pairs are used, the emitter should be powered from a separate power source (for example, using PBA-1, etc.). The NPN output(s) of MULTI-BEAM power block models PBT and PBT2 may be connected directly to the input (terminal #5) or to the auxiliary input (terminal #3) of any Banner B-series logic model. The MULTI-BEAM is powered by the MRB chassis as shown. Additional logic may be added on a longer chassis. Banner PLUG-LOGIC modules may also be used. P/N 03499 Rev.

Most counters, totalizers, rate meters, etc., including the batterypowered LCD types, accept the NPN output of MULTI-BEAM power block models PBT and PBT2 as an input. Counters which are powered by AC line voltage usually offer a low voltage DC supply with enough capacity to power one MULTI-BEAM (≥10 V DC at ≥60 mA). ## Banner Engineering Corp.
