Description
The National Instruments PXI-2523 PXI Relay Module, with Part Number 778572-23, is a high-performance switch featuring DPDT armature relays across its 26 channels, suitable for a variety of signal routing needs.
This module is capable of handling a maximum switching voltage of 100 V between channels and to ground, while being resilient against impulse voltages up to 500 V. It falls under Measurement Category I, ensuring safe operation with signal voltages under 100V, but with the capability to withstand higher impulse voltages momentarily.
Each channel of the NI PXI-2523 can manage a maximum switching power of 60 W or 62.5 VA (from DC up to 60 Hz) and a maximum switching current of 2 A, providing flexibility in controlling various types of electrical loads. The module maintains performance at an operating temperature of up to 55 °C when all relays are conducting maximum current.
Relay operation is both rapid and durable, with a typical operation time of just 1 ms and a mechanical life span of 1 × 108 cycles, signifying the module’s reliability over extensive use. It can reliably detect signals with a minimum pulse width of 150 ns when using PXI trigger lines 0-7, and even shorter pulses with digital filtering disabled.
Designed to fit within a single slot in a 3U PXI chassis, the NI PXI-2523 is not only compact but also energy-efficient, making it an ideal choice for integrated test, measurement, or automation setups.
