Signal amplifier AM-TOP series

powercurrentvoltage

• OPTOCOUPLED STATIC OUTPUT • 1 Timed channel General Features: These units allow to amplify signals from NAMUR sensors or contacts. The delay time and hold time respect the input signal are adjustable through potentiometers on the front panel. Each output is electrically insulated from each other, from power supply and from all the inputs. It is possible to configure them as N.O. or N.C. and use them as PNP or NPN. They are protected against over voltages on lines, overload and short circuit. On the 24V version is also possible to configure the OUT2 with the same funtion of OUT1 or use it as remote failure indication. When used for NAMUR sensors, the indication of failures is visible with a red LED on the front panel for interruptions or short circuits on the input lines. The configuration dip-switches are easily accessible removing the front panel. Suitable for DIN rail mounting.
