The PAB 20 is a 2-channel, multiplexed, photoelectric amplifier to be used in conjunction with two sets of remote light transmitters and receivers from the series 100, 110, 120. The two channels operate independently of each other with the multiplexing function ensuring that optical cross talk between channels is prevented.
The series offers manual sensitivity adjustment for each individual channel via an integral potentiometer located on the front panel of the amplifier, a choice between two individual relay or two individual transistor outputs with an adjustable 0-10 sec on/off time delay, light or dark function and long or short range switch selectable.
Up to nine amplifiers from the PAB series can be connected via a bus rail connector to form a modular master/slave system with up to 29 channels. The bus connection enables communication between the amplifiers, which allows the channels of all the amplifiers to be multiplexed ensuring that optical cross talk between channels is prevented and allows a common output from the amplifier modules. Both the PAB 20A and PAB 20S can share power supply via the bus connection.
