3. DESCRIPTION The PL3 M is a complete modulated LED amplifier in a plug logic package it is intended for OEM use in systems already containing power supplies and solid state logic It may be powered by 12 to 18 VDC and has a switched logic level output 10 milliamps maximum that is high in the light state and low in the dark state It may be used with any of the LED scanners listed on pages 62 65 of the product catalog however range will be reduced by 50 in all cases Hookup is identical to that for M Series amplifiers except that pin 3 is used for sensitivity adjustment rather than for inhibiting SPECIFICATIONS Supply Voltage 12 to 18 volts DC at 75 milliamps nominal ripple must be less than 10 Output Short circuit proof open collector with 560 ohm output impedence Ifa voltage output is required a 10K ohm resistor should be connected externally between pins 7 and 8 The output is logic level only and should not be used with relay type or current type loads It will interface directly with the input pins of any B Series amplifier l Operating Mode Output transistor conducts sink to ground when receiver is dark output transistor is off when receiver sees light Any number of out puts may be tied together to create or logic A dark or B dark or C dark output Also A light and B light and C light output Range Depends entirely on scanners and scanning modes used and will in all cases be 5
