The WTX4 is a Data Acquisition and Control module that is available in various different versions that provide a wide assortment of input and output combinations. Each WTX4 unit is comprised of four individual sub units which can be a mix of the following different types of I/Os.
DIGITAL INPUT – Used to read the on/off states of dry contacts for switches, proximity sensors, optical encoders, TTL level pulses, NPN or PNP sensor outputs, etc. Can also count event pulses, measure the RPM of a rotating shaft, or track the position of a quadrature encoder.
DIGITAL OUTPUT – Used for TTL level outputs, or high current open collector outputs to control the on/off states of relays, solenoids, magnetic latches, flow valves, DC motors, etc. Provides PWM control signals as well as Timer outputs.
ANALOG INPUT – Used to read the voltages from pressure transducers, load cells, strain gages, temperature sensors, 4-20 mA devices, potentiometer positions, etc.
ANALOG OUTPUT – (coming soon) Used to output DC control voltages to machinery that requires a ±10V control signal. Includes an internal automatic ramp generator with trapezoidal or S-curve shaped slope profiles.
THERMOCOUPLE INPUT – (coming soon) Used to read the voltages from types J, K, T, E thermocouples and convert it to absolute temperature using a built-in high-order polynomial equation.
