Overview and Applications:
- The NI PXI-2527 and PXIe-2527 are high-voltage multiplexer switch modules 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.

Automatic Scanning:
- 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. You can most efficiently implement scanning by mating an NI 2527 with an instrument such as an NI 407x FlexDMM, which issues a trigger after each measurement.

Relay Count Tracking:
- These switch modules count relay closures on each of their relays. Relay counts are incremented each time a relay is actuated. You can retrieve the counts, stored on board the modules, programmatically and use them for predictive maintenance to reduce unexpected system downtime.

Simplified Signal Connectivity:
- Make signal connections for the NI 2527 modules in the TB-2627 front-mounting screw-terminal block. Additionally, to simplify connectivity with a DMM, use the HV6-BAN4 cable, which connects the banana jack inputs of a DMM to the COMs of each multiplexer bank.

Software:
- All National Instruments PXI switch modules are shipped with NI-SWITCH, an IVI-compliant driver that offers complete functionality for all switch modules. For additional assistance in configuring, programming, and managing higher-channel-count switching systems, NI Switch Executive software provides an easy-to-use, intelligent switch management and visual routing environment. Use the NI-SWITCH soft front panel for simple relay operations or debugging switch code/execution.
