PXI-6515

The PXI‑6515 is an industrial digital I/O interface with eight banks of isolated channels. You can wire each input bank in a source or sink configuration. With programmable power-up states, you can configure the initial output states in software to ensure safe operation when connected to industrial actuators. If a computer or application fault occurs, the PXI‑6515 can use digital I/O watchdogs to switch to a configurable safe output state to ensure detection and safe recovery from fault conditions. Programmable input filters eliminate glitches/spikes and provide debouncing for digital switches/relays through a software-selectable digital filter.

2. Electrical Isolation and Noise Immunity
With built-in isolation, the module protects the PXI system and connected devices from voltage spikes, electrical noise, and ground loops.

3. Factory Automation and Process Control
It is suitable for controlling and monitoring industrial processes, production lines, and automated machinery.

4. Equipment Monitoring and Control Systems
PXI-6515 can be used to monitor equipment status (ON/OFF, alarms) and control system operations in real time.

5. Hardware-in-the-Loop (HIL) Simulation
The module is ideal for HIL applications requiring both digital input acquisition and output control for real-time system validation.

6. Automated Test Equipment (ATE)
It is commonly integrated into automated test systems to manage digital control signals, trigger instruments, and interact with DUTs.

7. Research, Development, and System Integration
PXI-6515 is widely used in R&D labs and engineering environments for prototyping, system validation, and industrial interface development.
