The National Instruments PXI-2527 / PXIe-2527 32-Channel (2-Wire), 300 V Multiplexer Switch are designed for medium- to high-density automated test systems. With a switching capacity of up to 300 VDC/300 VAC and up to 2 A, an NI 2527 acts as an effective front end for NI 4070 and NI 4072 digital multimeters (DMMs), offering simple channel expansion for voltage, current, resistance, capacitance, or inductance measurements. NI provides multiple-channel configurations including 64x1 one-wire, 32x1 two-wire, and 16x1 four-wire. Each channel, using robust electromechanical relays, is capable of scanning up to 140 channels/s. A cold-junction compensation (CJC) sensor is also included in the front-mounting terminal block to assist in thermocouple scanning applications.

NI 2527 switches are able to maximize throughput in automated test applications with the use of scanning. Scanning improves throughput by downloading a list of up to 32,000 connections to the switches and cycling through the list using an event (trigger) without any interruption from the host processor.
