RS-232 Compatible Photoelectric Sensors Feature Computer Screen Set Up, Monitoring And Control!
Tanpa,Florida: TRI-TRONICS COMPANY,INC. has introduced the first Photoelectric Sensors that can be set up, monitored and controlled directly from a computer screen. The new DCS SAMRTEYE Digitally Controlled Sensors are compatible with computers, PLC's, imbedded controllers or any control device equipped with an RS-232 serial port.
Using "point and click" icons on the screen, the universal DCS Sensors can be easily configured to perform a wider variety of sensing tasks than any other single sensor. They are also the first sensors that provide an on-screen "oscilloscope style" Contrast Deviation Analyzer (Patent Pending) that allows the operator to easily "tweak" the adjustment to guarantee the most reliable setting.
Important benefits of computer screen control:
*Icons Simplify Set-Up
*Graphical Performance Monitor
*Configurable Performance Options
*Unlimited Performance Memory Settings
*Multiple Timer Options
*Tamper Proof
Once the particular performance features have been set for different products, they can be stored in memory and easily recalled later.
