Photoelectric Amplifier Series Multiplexed Amplifier Series MPA 81

Description

Operation mode and max sensing range: Thru beam : 0-35 m Diffuse proximity : 0-3 m 230 V ac, 115 V ac, 24 V ac or 24 V dcsupply voltage Manual sensitivity adjustment Adjustable on/off time delay 8 relays or 8 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 81 is to be used in conjunction with 8 sets of remotetransmitters LT and receivers LR, from the series 100, 110 and 120.The 8 channels operate independently of each other with their own set ofremote transmitter and receiver. The multiplexing function ensures that optical cross talk between channels is prevented. The series offers a choice between 8 individual relays or 8 individual NPN/PNP transistoroutputs, or 1 common relay and 1 common NPN/PNP transistor outputwhich has an adjustable 0-10 sec on-off time delay.This amplifier series offers manual sensitivity adjustment for eachindividual channel, via integral potentiometers located on the front panel of the amplifier. Light or dark function and long or short range is switch selectable for each individual channel. Technical Data
