Relay Count Tracking

Overview and Applications

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.

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.

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.

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.
