80-Channel SPST Switch Module

The TF85182 is an 80-channel universal switch that fits into a standard PXIe bus. TF85182 works mainly in testing situations where a great number of signal channels need to be switched. TF85182 finds its typical applications in multi-channel testing of aerospace and national defense electronic systems; the reliability verification of automotive electronic ECUs and wiring harnesses; industrial power module and circuit board isolation testing, and laboratory automated test platform signal routing. When conducting experiments, the operators program the equipment in advance based on the testing plan. Then the connection lines in the test system do not need to be changed. All channel switching of the TF85182 can be controlled automatically, whereby the testing efficiency is significantly increased.

The TF85182 universal switch module consists of 80 single-pole single-throw relays. TF85182 is equipped with electromagnetic relays, which ensure that medium-power signals will be handled with excellent isolation between channels and high sensitivity. The maximum switching voltage and current of the TF85182 module are 300VDC/250VAC and 2A, respectively. Upstream software can be used for the control of the switch on or off status of any channel through auto-control of the TF85182 switch. Channel-on condition of TF85182 enables a stable and reliable two-way signal transmission system. The channel bandwidth of TF85182 can reach up to 60MHz. 

The isolation switch in the channel-off condition causes the two channels to be separated physically, thus preventing interference and ensuring the channel's stability and reliability. Besides, the MT5182 is also endowed with the counting function to keep track of the number of times the relays are used.

TF85182's total height is 3U, and TF85182's width is 4HP. All the channels TN TF85182 are extended to the front panel 160Pin connector, where TF85182's characteristic impedance is 50Ω. TF85182 combines the traits of high channel density and compact structure.

1.Q:‍‌‍‍‌‍‌‍‍‌ What are some of the application types that would be most suitable for 80 SPST channels?
A:The number of channels on this scale is incredibly high, and the potential applications could be a vehicle wiring harness test in the automotive industry, a power module validation, and a multi-point signal routing, where numerous signals have to be switched at the same time in aerospace, automotive, and industrial systems.
2.Q: What power levels can this device handle?
A: It can carry a maximum current of 2 A, and the switching voltage is 300VDC/250VAC; thus, it can be used for medium power applications such as power supply testing, relay control, and industrial automation signals, which are beyond the range of low-power relays.
3.Q: How will the 60MHz bandwidth influence signal integrity?
A: One needs a certain amount of bandwidth to separate a particular signal from noise and other signals. So, a 60 MHz bandwidth implies that analog and digital signals can still be very cleanly transmitted up to that frequency. The result is the preservation of signal integrity, which is of the utmost importance in cases of RF testing, audio, and high-speed digital ‍‌‍‍‌‍‌‍‍‌switching.
4. Q: What's the advantage of the 160-pin front connector?    
A: The 160-pin front connector is a very high-density connector. It is one single point to access all the 80 channels, and the characteristic impedance is 50Ω, so the reflections of the signal are minimal. The connector thus simplifies the integration of the system in those applications where there is a very high channel count.
5. Q: How does the relay counting function support long-term reliability?    
A: Continuous usage can now be accurately predicted with the help of the relay counting feature. It means that the operation of relays can be closely monitored against the 100 million-cycle lifetime and failures are avoided. This is very useful especially for production test environments where the test cycles are running ‍‌‍‍‌‍‌‍‍‌constantly.
