USB-1024LS Measurement Computing 24-line USB digital I / O card NEW

Description

USB digital device with 24 digital I/O, one 32-bits counter input (Maximum input frequency: 1 MHz), screw terminals. Includes a 3 m (9.8 ft) USB cable. Windows and Linux compatible.
The programmable DC continuous power supply of the SPD3000X series has a 4.3-inch TFT-LCD screen, supports remote programming and has a real-time waveform display.SPD3000X-E has three isolated outputs; two adjustable channels and a selectable channel of 2.5v, 3.3V and 5V. It also has protection against short circuits and output overload and can be used in production and development.
Features:
Protocol: PROFINET IO Device.
3 isolated and independently controlled outputs: 32V / 3.2A × 2, 2.5V / 3.3V / 5V / 3.2A × 1,total 220W.
5-digit voltage, 4-digit digital display, minimum resolution: 1mV.
Supports front panel timing outputs.
TFT-LCD color screen 480x272 4.3 inches.
3 types of output modes: independent, serial, parallel.
Design compatible with 100V / 120V / 220V / 230V to meet the needs of different electrical networks.
Intelligent fan controlled by temperature, effectively reduces noise.
Clear graphic interface, with waveform display function.
Five internal groups of saving / recovering system parameters support the expansion of the data storage space.
