VT5838
Multi-IO Module
The VT5838 offers 8 differential analog voltage inputs, 14 analog voltage outputs and 16 digital channels that can be either input or output. In addition, it offers two RS422 interfaces, two LVDS interfaces, one IBC+ and one Ethernet port.
The module VT5838 always comes with a user programmable FPGA and all inputs, outputs and interfaces are directly connected to this FPGA. Therefore, simulation models or control loops with very short cycle times can be created.
Characteristics
Functions
- Digital channels can be used as inputs and outputs

- Two galvanically isolated groups of analog inputs
- Two groups of analog outputs (±10 V / ± 15 V)
- Relay for signal path interruption at the ± 15 V outputs
- 16 project-specific LEDs on the VT5838 front panel
- User-programmable FPGA
- USB-Blaster® (JTAG Interface) for user programmable FPGA
