The PXIe-2569 (Part Number: 780587-69) is a 100-Channel Relay Module from National Instruments, with a single-pole single-throw relay. The module also implements the mechanism for input and output triggers. The source and destination for the triggers are PXI trigger lines. The value of the minimum pulse width for the input triggers is 150 nanoseconds. It enables the user to program the output triggers. Their pulse width ranges from 1 microsecond to 62 microseconds. This module also offers a step scan capability. The NI PXIe-2569 Relay Module comes with a built-in step scan list of 32,000, which enables the user to utilize deterministic scanning.

The PXIe-2569 offers a maximum switching voltage of 100 volts. This value is for the channel-to-channel voltage. The value for the channel-to-ground switching voltage is also 100 volts. This module is specifically designed for Measurement Category 1. This module implements a feature for protection against impulse voltages. The instrument has the capability to withstand the impulse voltage of 800 volts. The NI PXIe-2569 Relay Module implements an additional protection feature to ensure smooth operation of the module against high voltage transients. These transients may occur due to switching inductive loads.

The PXIe-2569 Relay Module offers a value for minimum switch load of 20 mV or 10 mA. The initial value of DC path resistance for the instrument is less than 0.55 ohms. Its value at the end of the life of relay is one ohm. The typical bandwidth of the NI PXIe 2569 is greater than or equal to 20 MHz.
