The Photoelectric Amplifier Bus (PAB) series has a total of 3-channel photoelectric amplifier. These amplifiers are used in conjunction with Telco remote transmitter LT and receiver LR. Using the integral potentiometer placed on the front panel, the series gives a manual sensitivity adjustment. With a 0-10 sec on/off time delay, the output can be selected on a relay or transistor output. The user can choose light or dark function and long or short range.
The series can connect a total of 9 amplifiers using a bus rail connector placed on the DIN rail. The bus connection between the amplifiers enables communication. By connecting the amplifiers, a modular slave system is formed. This system consists of 28, 29 or 30 channels in accordance with its PAB type.
