FMA-02A Single Channel Filter Mounting Assembly For 424, 428, 824 & 828 Series Modules Description The FMA-02A is a filter mounting assembly that eliminates the need to breadboard or hand-wire filter modules into individual test set-ups. The FMA-02A is a factory assembled 3" x 5" printed-circuit board with socket pins for filter insertion, various electronic components, and screw terminal connections for power and signal input/output. FMA-02A’s will operate any of the low-pass, high-pass, band-pass or notch 424, 428, 824 and 828 series filter modules. Features/Benefits: • No more building of breadboards. • Utilized as a single channel bench-top test set or rack mounted via mounting holes for instrumentation applications. • Accepts a broad range of programmable filter modules allowing for selected cut-off frequencies and transfer functions specific to each application. • Provide quick and easy connection between circuit card and wired electrical circuits. • All external connections are easily made with a screwdriver, reducing engineering design, set-up and test time. Applications • Aerospace, navigation, sonar applications • ATE, research and development • Automotive and transportation • Communication systems and electronics Low-Pass 424 824 428 828 Filters Available 4-pole 4-pole 8-pole 8-pole 10.0 1.00 10.0 1.00 Hz Hz Hz Hz to to to to 102.4 102.4 102.4 102.4 kHz kHz kHz kHz High-Pass 424 824 428 828 Filters Available 4-pole 4-pole 8-pole 8-pole 10.0 1.00 10.0 1.00 Hz Hz Hz Hz to to to to 102.4 102.4 102.4 102.4 kHz kHz kHz kHz Band-Pass Filters Available 824BP 2-pole pair 1.00 Hz to 102.4 kHz 828BP 4-pole pair 1.00 Hz to 102.4 kHz • Data acquisition systems • Industrial process control • Medical electronics equip. and research Band-Reject (Notch) Filters Available 828BR 4-pole pair 1.00 Hz to 102.4 kHz • Sound and vibration testing • Noise elimination • Signal reconstruction 1 1784 Chessie Lane, Ottawa, IL 61350 • Tel: 800/252-7074, 815/434-7800 • FAX: 815/434-8176 e-mail: [email protected] • Web Address: http://www.freqdev.com FMA-02A Single Channel Filter Mounting Assembly For 424, 428, 824 & 828 Series Modules SCHEMATIC 824/828 D5 D4 D2 GND D1 D0 D3 A2 OUT +VS -VS M1 OUT R7 GND D7 IN OS R3 GND R5 A1 D6 R2 IN R4 R6 P1 SW1 OUT +VS OS M2 -VS Vout= R6+2.49k Ohms Vin(output stage) R6 D3 D0 D2 +5V GND R4+2.49k Ohms Vin(input stage) Vout= R4 Amplifier stage A2 is configured Amplifier A2 ismay configured for unity stage gain.
