Signal Converter Boards

High-Pass Compliance Amp

The High-Pass Compliance Amplifier is a 4th-order adjustable frequency high-pass filter, with a fixed low pass stage. It is commonly used as a bandpass filter for hydraulic compliance applicatoins. Each board provides one channel and switched filter settings.


Part Number: Hipass 1A
Power input: +12VDC or +/-5VDC
Output range: +/-5V
Dimensions: 2.8" x 1.4" (71mm x 36mm)

MOSFET Switch - 8 channel

The Mswitch-8ch board provides eight 10 amp MOSFET transistors suitable for switching heavy loads with only a 3.3V TTL/CMOS input. Jumpers on the board allow any particular switch to be set permanently on. Optional resettable fuses per-channel.


Part Number: Mswitch-8ch
Dimensions: 1.5 x 4.0" (38.1mm x 101.6mm)

Analog Buffer Board

The Analog Buffer Board reduces unwanted high-impedance of signals, and can also be used as a fixed-gain amplifier. Each board provides two channels which can be independently gain-adjusted.


Dimensions: 0.61" x 1.0" (15.64mm x 25.40mm)

Logic Level Shifter Board

The Logic Level Shifter board converts up to six digital logic signals, in the range of 3.3V to 15V, to 5V CMOS/TTL level. Input power in the range of 5.5 - 14V may be supplied. Signals are not inverted. The board may also be used as a buffer/line-driver.


The LCON board raises a single digital logic signal, in the range of 0.7V to 16V, to a 10V logic level. Input power in the range of 11.2V - 16V may be supplied. The input signals is not inverted, thus the board may also be used as a line-driver. Output current up to 200mA, so the board can be used to drive a load.

Dcon Buffer Board

The Dcon board is a four channel non-inverting buffer. It conditions digital signals such that logic up to 15V will be down-converted to 5V TTL/CMOS levels.
