24-Chn Digital Input
4-Chn Thermocouple

24-Chn Digital Input 4-Chn Thermocouple
  • 24 wide-range digital input channels with high voltage transient protection.
  • 4 differential thermocouple input channels with a 10V common mode range and protection to 40V.
  • Electrically isolated from the power supply rails, the communications bus, and the RS-232 / USB port.
  • Digital Inputs incorporate user programmable pull-up or pull-down resistors for use with either NPN or PNP sensors.
  • Digital Inputs respond to button presses and switch transitions using automatic debounce and typematic repeat with adjustable delay.
  • Logic state of each digital input channel can be read (or polled) by the host PC, or each channel can be set up to automatically report a logic transition without polling.
  • 24 event counter inputs with 24-bits each and adjustable rollover limits.
  • 12 quadrature encoder inputs with 24-bits each and adjustable rollover limits.
  • 12 tachometer inputs which read the speed of a rotating shaft from 200 to 400,000 RPM.
  • Thermocouple Inputs accept types J, K, T, E (ungrounded) thermocouples.
  • Thermocouple Inputs individually selectable to read temperature in Fahrenheit or Celsius.
  • Temperature conversions use high-order polynomial equations eliminating look-up table interpolation errors.
  • Built-in cold junction reference, no external ice-point necessary.
  • Software calibrated; no trim-pots to adjust.
  • All user configuration and calibration data stored in non-volatile memory.
  • Wide power supply range (10 to 30 VDC).

The WTX4 is a Data Acquisition and Control module which is available in various different versions that provide a wide assortment of input and output combinations. Multiple units can also be plugged together to create an expandable network. Each WTX4 unit is comprised of four individual sub units which can be a mix of Digital Inputs, Digital Outputs, Analog Inputs, Analog Outputs, and Thermocouple Inputs.
