The PA 01, from Telco Sensors, is a 1 channel photoelectric amplifier, which is used in conjunction with a set of remote transmitter (LT) and receiver (LR) from the series 101, 100, 110 or 120.
The amplifier series offers a choice between automatic and manual sensitivity adjustment with or without a 0–10 sec time delay via integral potentiometers located on the front panel of the amplifier. Output can be selected from a relay or NPN/PNP transistor, light or dark function and long or short range selection.
In automatic mode set-up is required, which is achieved by pressing the teach-in button located on the front panel. This unique feature ensures that the transmitting power level is adjusted according to the application, thus achieving optimal hysteresis and excess gain. Once initialised, the system will automatically compensate for moderate misalignment and contamination during operation. In manual mode, the teach-in button allows for an overall manual system test by temporarily disabling the transmitter. The sensor LED drive powers the optional monitor LEDs available on the remote sensors - output (LT) and power (LR). The feature STF allows up to three identical systems to operate within a close distance of each other without optical cross talk as each system automatically maintains different transmitter frequencies.
The remote sensor series is available in a wide range of housings, with either cable or plug connection, and may be used in through-beam or diffuse proximity mode.
