PABA amplifier modules in bus connection
Up to 10x PABA modules can be connected in bus connection
PABA 10 A
The PABA 10 is a 1-channel photoelectric amplifier, which is to be used in conjunction with a set of remote transmitter LT and receiver LR from the series 100, 110 and 120.
This amplifier series offers versatile automatic gain adjustment with potentiometer adjustable excess gain and switch selectable long or short range which ensure 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. Output can be selected from either a relay or transistor output, with an adjustable 0-10 sec on/off time delay. Light or dark function is switch selectable.
The amplifiers from the PABA 10 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 28 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 10 A and PABA 10 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).
