Connect Sensors Directly with Isolation Isolation is a form of built-in signal conditioning that provides an extended voltage range for direct connection to industrial sensors and actuators. NI 6528 and PXI-6529 devices provide channel-to-channel isolation where every channel is physically and electrically separated from the others and earth ground. Optical isolators separate the high- voltage front end from the low-voltage back end, breaking ground loops, improving common-mode voltage rejection, and protecting computer circuitry from hazardous voltages. Industrial environments containing machinery and inductive loads require isolation to protect the electronics from transient voltage spikes and provide greater common-mode noise rejection. Achieve Glitch-Free Startup with Programmable Power-Up States Using programmable power-up states, you can configure the initial NI 6528 output states in software to ensure glitch-free operation when connected to industrial actuators such as pumps, valves, motors, and relays. An NI 6528 holds these output states after receiving power, so your computer can boot and your software application can begin running. Programmable power-up states are glitch-free, meaning the outputs never go through an incorrect state during power up. You can configure each individual digital line as high-output or low-output. An NI 6528 stores the settings in onboard nonvolatile memory and implements the power-up states instantaneously after power is applied to the device. Detect Faults and Recover with Digital I/O Watchdogs Digital I/O watchdog timers are an innovative technology that can detect a variety of fault conditions, such as an application crash, and automatically respond by setting the outputs to a user-configured safe state. Watchdogs are important whenever the module is connected to actuators such as pumps, valves, motors, and relays. An NI 6528 monitors the software application; if the application fails to respond within a preset time limit, an NI 6528 automatically sets the output lines to a user-defined safe state. An NI 6528 remains in the watchdog state until the watchdog timer is disarmed, an NI 6528 is reset, or the computer is restarted. Trigger Your Application with Change Detection With change detection, you can automatically trigger your software application to perform a digital read operation upon a digital change of state. A digital change of state is defined as the rising edge (0 to 1 transition) or falling edge (1 to 0 transition) on one or more digital lines. Using change detection, you can monitor for digital events with minimal processor usage. No polling is necessary because the digital I/O module generates an interrupt to automatically wake up your application. Using NI-DAQmx software technology, NI 6528 and PXI-6529 devices notify the software application when an event is detected, causing the application to automatically perform a read operation. To minimize the effects of noisy input lines, use programmable input filters in combination with change detection to eliminate spurious change- detection events caused by noise or glitches. Eliminate Noise with Programmable Input Filters Programmable input filters remove noise, glitches, and spikes on inputs as well as provide debouncing for digital switches and relays. These features are important for applications in industrial environments to prevent false readings caused by noise. You can configure the programmable input filter for each digital line by setting the filter time. NI 6528 and PXI-6529 devices block any digital noise, glitch, or spike that is shorter than half of the specified filter time, preventing invalid readings and false triggers for change-detection events. Use High-Voltage Triggering With NI 6528 and PXI-6529 devices, you can route isolated high-voltage (±60 VDC) signals to the PXI trigger bus or RTSI (Real-Time System Integration) bus, so you can synchronize between multiple high-voltage devices without additional circuitry. This feature benefits automotive, aerospace, and industrial monitoring and control applications needing high-voltage triggers.
