National Instruments USB-6525 Digital I/O Device
The NI USB-6525 (Part Number: 779640-01) is a device from National Instruments. The USB 6525 has 8 input channels. All the channels are digital in nature. These inputs work at ±60 VDC. All the channels are isolated. This isolation is provided from one channel to the other channel. This amazing device also includes 8 SSR outputs. SSR refers to relays that are solid state. All of these output channels are also isolated. This isolation is provided from one channel to the other channel. The output channels work at 60 VDC. The varying voltage for the output channels is 30 Vrms.
The USB DAQ 6525 also includes a counter. The frequency of this counter is 5 kHz. This counter has a resolution of 32-bits. This device includes a mainboard of M-Series. It is used for data acquisition purpose. This high-performance device offers 18-bits of accuracy for analog inputs. The 5 digits measurements of DC and 18-bit resolution measurements are equivalent. This module also includes an amplifier, which provides superb linearity. The USB-6525 National Instruments additionally incorporates low-pass filters, which are programmable. These filters reject the noise of high-frequency and block aliasing.
The National Instruments NI USB-6525 includes a feature of change detection. This device sends an interruption in case of any change. It detects a change in the input line(s) and sends this interruption. The user can program this device to use this feature. The typical delay of propagation is 65 µs for the isolated inputs. The lowest value of pulse-width is 200 µs for a change detection in isolated inputs. The switching current in SSR outputs of the NI DAQ USB 6525 is 500 mA maximum.
The USB 6525 weighs 2.3 oz (without connectors) and 3.1 oz (with connectors). It measures 2.50 x 3.35 x 0.91 in. (without connectors) and 3.22 x 3.35 x 0.91 in. (with connectors) in physical dimensions. The device has a recommended operating temperature range of 0 to 55 °C, a storage temperature range of –40 to 85 °C, non-condensing operating and storage humidity ranges of 10 to 90% RH and 5 to 90% RH respectively.
