Description
The USB-2019 provides easy USB plug-and-play operation and accurate measurement for all kinds of automation applications.
Compared with the traditional PC-based card like PCI, PC/104 and ISA cards, users can achieve data acquisition easier and quicker via USB-2019. The USB-2019 is an 8-channel universal analog input module and provides the following features.
- Provides over-voltage protection of up to 240 Vrms
- Voltage and current input types.
- Supports thermocouple devices with J, K, T, E, R, S, B, N, C, L, M and LDIN43710 types.
- Accurate thermocouple measurement and automatic cold-junction compensation for each channel.
- Open wire detection for thermocouple and 4 ~ 20 mA inputs for each channel.
Using the USB I/O utility, users can configure and test the USB-2019 directly and easily without any coding. The friendly API library is also provided for users to develop their own USB application.
