Flexible remote sensor controller
July 2001
PLCs, DCSs & Controllers
The PA 11 remote sensor amplifier from Gail Norton Instrumentation 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 manual sensitivity adjustment via integral potentiometers located on the front panel of the amplifier. Output can be selected from either a relay and NPN or NPN and PNP transistor outputs with or without a 0-10 s on/off time delay. Light or dark function and long or short range is switch-selectable.
The microprocessor-controlled sensor test ensures that the system will automatically detect and indicate a faulty transmitter or receiver - cable break or electrical failure - during operation, through the relevant LED located on the front panel. The sensor LED drive powers the optional monitor LEDs available on the remote sensors - output (LT) and power (LR).
The operational range depends on operational mode, providing a range of 0 to 2,5 m (in diffuse proximity mode) and 0 to 45 m (in through-beam mode). The devices run off 230 or 115 V a.c. as well as 24 V a.c./d.c. Sensitivity may be manually or automatically adjusted and there is an adjustable on/off time delay.
