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.
