The PABA 30 is a 3-channel photoelectric amplifier, which is to be  used in conjunction with 3 sets of remote transmitters LT and receivers  LR from the series 100, 110 and 120. The 3 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.

This amplifier series offers  versatile automatic gain adjustment with potentiometer adjustable excess  gain (for each individual channel) and switch selectable long or short  range which ensures that the transmitting power level is adjusted  according to the application, thus achieving optimal hysteresis and  excess gain. Once set up, the amplifier will automatically and  continuously compensate for moderate contamination and misalignment  during operation in accordance with the selected auto gain settings. The  series offers a choice between 3 individual relay or 3 individual  transistor outputs, with an adjustable 0-10 sec on/off time delay. Light  or dark function is switch selectable. 

The amplifiers from the  PABA 30 A series can be connected together with up to 9 amplifiers from  the PAB(A) series via a bus rail connector positioned on the DIN rail,  to form a modular master/slave system with up to a total of 30 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 PABA 30 A and PABA 30  S can share power supply via the bus connection (except 90-240 V ac  types). 

The amplifier offers a test input, which is used for  either disabling or enabling the transmitting power temporarily for test  purposes. The system includes an alarm output, which is used to  indicate if the transmission power is at maximum and the selected excess  gain level is not obtained or if a sensor is faulty/disconnected. The  sensor LED drive powers the optional monitor LEDs available on the  remote sensors – output (LT) and power (LR).
All products include a 3-year worldwide warranty.
