Description
The USB-2026 is a USB powered multifunction module that offers 5 analog input channels, 2 analog output channels, 2 digital input channels and 2 digital output channels, in a small form factor.
The USB-2026 provides a programmable input range on all analog inputs (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA or 0 ~ +20 mA), analog outputs are 12-bit at +/-5 V, +/-10 V, 0 ~ +20 mA or +4 ~ +20 mA and all digital outputs can be set as alarm output. Each analog input can be configured for an individual range and provide a high overvoltage protection of 240 Vrms.
