Telco PA - a new era in PA controllers

March 2001 Sensors & Transducers

The new Telco PA controllers are user friendly, with effective elimination of cross talk and interference from other systems.

The recently launched PA01 Series designed for the door and gate industry was the first of the new range, with new models still being added.

Using the latest opto-electronic technology and Telco's unique signal tracking feature (STF) means that the new controller automatically re-adjusts to a safe position if interference is detected from any source, so the user does not need to worry about signals from other photo-electric systems, electrical noise, light sources or even dirt and dust on the sensor head.

The system is suitable for a wide range of applications: switching from automatic to manual mode, for example, or for applications where time delay of functions is necessary. Anywhere where automatic operation is called for ... in conveyor systems, materials handling or food and beverage manufacturing for example. A 'last set-up' memory function is a useful feature - especially in a power break situation. Once the system is installed, it will not need re-checking.

The traditional Telco housing allows users to install the miniature sensors so that they stay well hidden and they come in many different shapes.

The original PA 01 for the door industry; the PA 01 B with adjustable gain options, and with manual or fully automatic modes which are particularly suited to industrial applications; and a PA 01 D with a one-shot timer that is adjustable from 0 to 30 s - good for the elevator industry and a wide range of other applications.
