High-Pass Compliance Amp
![](images/hipass-5Hz_201812_2c.500x300.png)
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.
Specifications
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
![](images/mswitch-8channel.520x316.png)
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.
Specifications
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.
Specifications
Dimensions: | 0.61" x 1.0" (15.64mm x 25.40mm) |

Logic Level Shifter Board
![](images/levshift_rev1A-500x350.png)
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.
LCON

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.
