Photoelectric Amplifier Series Multiplexed Amplifier Series MPA 21

Description

Operation mode and max sensing range: Thru beam : 0-45 m Diffuse proximity : 0-3,5 m 230 V ac, 115 V ac, 24 V ac or 24 V dc supply voltage Manual sensitivity adjustment Adjustable on/off time delay 2 relays or 2 transistor outputs Power, output and signal level indicators Switch selectable light or dark function Switch selectable long or short range 11-pole DIN socket connection

The MPA 21 is to be used in conjunction with 2 sets of remotetransmitters LT and receivers LR, from the series 100, 110 and 120.The 2 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 2 individual relays or 2 individualNPN/PNP transistor outputs, with or without an adjustable 0-3 sec on/offtime 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
