The 7I89 can also supply 5V power to encoders. 5V encoder power can be optionally switched to allow reset of combined absolute/incremental encoders.   In addition to the 8 encoder inputs, a single RS-422/RS-485 interface is provided. This interface is compatible with Mesa's sserial I/O expansion cards. The controller connection is a DB25 connector that matches the pinout of Mesa's 25 pin Anything I/O cards.  All buffered I/O is terminated with 3.5 mm pluggable screw terminals (supplied)






7I89 MANUAL

  
The 7I88 is a  16 channel differential driver that can provide up to 8 differential Step/Dir or  8 PWM/Dir output channels. The last channel pair can be be used as a RS-485 interface if desired. All differential outputs have a full 5V swing and can be used single ended if required. 5V and GND conections are provided for all channels.  The controller connection is a DB25 connector that matches the pinout of Mesa's 25 pin Anything I/O cards.  All buffered I/O is terminated with 3.5 mm pluggable screw terminals (supplied)

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.

THCAD2  High isolation A-D accessory

The THCAD2 is a frequency to voltage converter type A-D designed for high noise environments like plasma voltage monitoring for torch height 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.
