Descrição

The Omega^TM FLSC-AMP amplifies the low level signals from the magnetic pickup of gear teeth or flow transmitters by a factor of more than a hundred times to drive any Omega ratemeter, counter or controller. It is mounted in a rugged 2 x 3" metal housing with screw terminals for easy installation.

SPECIFICATIONS
Power Requirements: 11 to 26 Vdc; 30mA Maximum
Input Characteristics:
    Input Impedance: 1500 Ω
    Input Frequency: 0-15 KHz
    Input Voltage: 0.020 to 50 V
Output Characteristics: Open Collector with internal 2700 ohms pull-up resistor to supply voltage. 100 mA Maximum sink to 1 v or less
Temperature Range: 0 to 60ºC (32 to 140ºF)

NOTE:
The low voltage line from the magnetic pickup to the FLSC-AMP should be less than 3 m (10') in length, shielded and isolated from relays, solenoids or other sources of electrical noise (let the output line make the long run). If the input is too sensitive, lower the 1.1K input impedance by adding a 220 to 1 KO resistor across TB1, pins 1 and 2, to increase noise immunity.
