THCAD
High isolation A-D accessory
The THCAD is a
frequency to voltage converter type A-D designed for high
noise environments like plasma voltage monitoring for torch
height controls.
The THCAD is available in three voltage
ranges, 0-5V, 0-10V and 0-300V. When used for plasma voltage
monitoring, the 5V and 10V versions require an external high voltage
resistor. The advantage of the 5V and 10V THCAD and external resistor is that
the resistor can be selected to work with high-frequency start
torches.
The 300V version of the THCAD has all input divider resistor on board
and can connect directly to the plasma voltage of touch start type
torches only. The THCAD has a frequency output range of approximately
100 KHz to 1 MHz. This can be counted directly by our FPGA cards for
conversion to voltage value. The
frequency output can optionally be divided by 32, 64 or 128 if the
output must be counted in software. Frequency and reference frequency
outputs are available. Both outputs are differential for high noise
immunity. The A-D has galvanically isolated inputs (2500V common
mode isolation). The 5V and 10V model can withstand a 500V input
overload indefinately. The 300V model can withstand a 2500V input
overload indefinately. Being a frequency to voltage type A-D,
resolution is sample rate dependent and approximately 10 bits at a 1
KHz sample rate and 12 bits at a 250 Hz sample rate. The THCAD is
normally used in unipolar mode but can be jumpered for bipolar mode for
non-plasma applications. The THCAD requires 5V at 150 mA for
operation. Pluggable screw terminal blocks are provided for all
connections.

controls. The THCAD2 has selectable 0 to 5V and 0 to 10V ranges. When
used for direct plasma voltage monitoring, the THCAD2 requires an
external high voltage resistor.
The THCAD2 has a frequency output range of
approximately 100 KHz to 1 MHz. This can be counted directly by our
FPGA cards or uControllers for conversion to digital voltage value. The
frequency output can optionally be divided by 32, 64 or 128 if the
output must be counted in software.
Frequency and reference frequency outputs are
available. Both outputs are differential for high noise immunity, but
can be used single-ended (TTL) if desired. The A-D has
galvanically isolated inputs (2500V common mode isolation). The THCAD2
can withstand a 500V input overload indefinitely.
Being a frequency to voltage type A-D, resolution is
sample rate dependent and approximately 10 bits at a 1 KHz sample rate
and 12 bits at a 250 Hz sample rate. The THCAD2 requires 5V at 150 mA for operation.
Pluggable screw terminal blocks are provided for all connections.
