4 Digital Input Channels

Digital input channel configuration and protection

The input channels of the USB Digital I/O Module are carried out optical and potential insulated in order to protect the hardware and give higher flexibility in design.

Voltage threshold levels of the digital input channels

The USB Digital I/O Module is available for 3 different threshold input voltages of the ranges 5V, 10V and 24V in order to interface with many different devices directly without conversion of input levels.

Digital input channel operation modes

In order to give most flexibility each of the 4 input channels of the USB IO Module can operate in one of the following modes:

Mode Function
Reflect Mode Samples a digital input signal and provide its conditioned and debounced state.
Edge Detection Mode High speed sampling of digital inputs and detecting rising or falling edges in real-time.
Count Mode Configurable high speed counter  allows to acquire a wide range of pulses and sensors.
Signal conditioning and debouncing

Filters can be applied to each input channel in order to suppress erroneous signal states.

High sampling rate

Ensures signal detection without activity of the host computer which is crucial in order to guarantee precise timing.

4 Digital Output Channels

Digital output channel configuration and protection

The optical and potential insulated outputs are realized by using solid state relays (SSR). The USB Relay Module with SSR provides the best overall capabilities and high protection level for controlling power loads like pumps, fans or heating elements by statically switching or by periodically pulsing. Each digital output is rated with 24 V and 0.75 A and can switch loads up to 18 Watt.

Digital output operation modes

The 4 outputs of the USB Relay Module can operate in different modes:

Mode Function
Reflect Mode Generates a digital output signal by setting the channels state directly.
Duty-Cylce Mode Generates a Pulse Width Modulation (PWM) by configuring cycle time and duty cycle.
This mode can be used in order to control the power of loads by pulsing them periodically.
On-Off Mode Generates a time sequenced output signal. Using this mode the USB IO Module can be used to realize e.g. time switches.
