MULTIPLEXED AMPLIFIER SERIES Description ■ Operation mode and max sensing range: Thru-beam: 0-35 m Diffuse proximity: 0-2 m ■ 230 V ac, 115 V ac, 24 V ac or 24 V dc supply voltage ■ Manual sensitivity adjustment ■ Adjustable on/off time delay ■ 4 relays and/or 4 transistor individual outputs ■ 1 relay and 1 transistor common output ■ Switch selectable light or dark function ■ Switch selectable long or short range ■ Power, output and signal level indicators ■ Screw terminals connection The MPA 41 is a 4-channel, multiplexed photoelectric amplifier, which is to be used in conjunction with 4 sets of remote transmitters LT and receivers LR, from the series 100, 110 and 120. The 4 channels operate independently of each other with their own set of remote transmitter and receiver. The multiplexing function ensures that optical cross talk between channels is prevented. The series offers a choice between 4 individual relays and/or 4 individual NPN/PNP transistor outputs, or 1 common relay and 1 common transistor output which features an adjustable 0-10 sec on/off time delay. This amplifier series offers manual sensitivity adjustment for each individual channel via integral potentiometers located on the front panel of the amplifier. Light or dark function and long or short range are switch selectable for each individual channel. Technical Data REMOTE PHOTOELECTRIC SYSTEMS I 1
