PX1-6514 NI Product Details

The NI PXI-6514 is an industrial digital I/O module with 64 channels. It features eight banks of isolated channels, offering 32 sourcing outputs and 32 sink/source inputs. This module is designed for reliable communication with industrial actuators and sensors.

Product Parameters

• Number of Channels: 64 (32 sourcing outputs, 32 sink/source inputs)
• Digital Input Voltage Range: -30 V to 30 V
• Output Voltage Range: -30 V to 30 V
• Logic Level Digital I/O: 24 V
• Current Output for Single-Ended Digital I/O: 250 mA (Note: maximum drive current may vary based on the number of lines used and operating temperature)
• Bus Type: PXI Hybrid
• Operating Temperature Range: 0 °C to 55 °C
• Relative Humidity Range: 10% to 90%, noncondensing

Product Advantages

• Isolation: Bank isolation provides enhanced safety and noise immunity for industrial applications.
• Programmable Power-Up States: Allows users to configure the initial output states via software, ensuring safe operation when connected to industrial actuators.
• Digital I/O Watchdog: In case of computer or application faults, the module can switch to a configurable safe output state, enabling fault detection and safe recovery.
• Programmable Input Filters: Software-selectable digital filters eliminate glitches and spikes, providing debouncing for digital switches and relays.

Precautions

• Ensure that the output Vcc (user-provided) is greater than 10 VDC to guarantee the output voltage is within the +4.3 VDC to +6.3 VDC range. The power at the I/O connector is derived from this output Vcc.
• Each output port has a self-resetting fuse for overcurrent protection. The actual current trip value may be lower depending on the device’s operating temperature, which is affected by ambient temperature, airflow, I/O voltage, I/O usage, and duty cycle. Refer to NI KnowledgeBase document “Why does my 651x Shut Down When Outputting Over Maximum Current?” for more information.
• When using all output lines at a 100% duty cycle, the maximum drive current for the PXI-6514 is 75 mA. When using only one output line in each bank at a 100% duty cycle, the maximum drive current is 350 mA.
• Follow the National Instruments installation, operation, and maintenance instructions carefully.
