& MC370AD7Q2 Remote Multiplexer/Module Cases The Surge Withstand Capability (SWC) tests were carried out in accordance with the IEEE STD 472-1974.
Tile tests were done on the input connectors of the MC170AD-Q2 and MC370AD-Q2 with and without the signal conditioners and power supplies plugged in. The signal conditioners subjected to SWC tests were the CD173-Q2, PT174-Q2, DI325-Q2, BA332-Q2, PC202-Q2, Q.1249-Q2 and TC292-Q2. ,The PS171-Q2 and PS294-Q2 were also plugged in during the SWC Test. Tests were performed at Validyne in February, 1982. The surge generator was constructed according to the schematic shown "in Figure 1. (Same as recoI1DI1ended by IEEE STD 472-1974.)
The SWC test wave *is an oscillatory wave., frequency range of 1.0 MHz to 1.5 MHz, voltage range of 2.5 kV to 3.0 kV crest value of the first half cycle peak, envelope decaying to SO cent of-the crest value of the first peak in not less than 6 µs from the start of the wave.

Then*each plug-in was*subjected to SWC test for 2 s*econds with common mode connection.
In transverse (differential) mode tlon the duration of each SWC test was 2 seconds for each pair of connections.
The MC170AD-Q2 and MC370AD-Q2 had the power on during SWC tests. The units were functionally retested after SWC exposure and were operating nonnally.
The MC170AD-Q2 and MC370AD-Q2 chassis were also subjected to SWC test without plug-in. The units were working normally after the SWC test. The signal conditioners*subjected*
to the SWC test were as follows: CD173-Q2 Input Pins :

The MC170AD-Q2 ana MC370AD-Q2 chassis did not have any tion because of SWC test. 3. The PS171-Q2 and PS294-Q2 were functioning normally after being subjected to SWC test.

- Telex No. 65*1303 REV VEC 305-11/IIO A[id)'NE DIQI_I_ COll~IIA110N ADDENDUM 1 to QTR82-003 Two additional signal conditioner units are also manufactured by Validyne as qualified to the SWC requirements of IEEE STD 472-1974.
These units are: (a} DI338-Q2 (or DI338-XXX-Q2}
and (b) BA332-1829-Q2 Both of these signal conditioners have equivalent configuration to other units which were directly tested in the February, 1982 tests. The BA332-1829-Q2 is identical to the BA332-Q2, with the addition of a single gain setting resistor.
The added resistor*is located in a part of the circuit which is not directly exposed to the SWC transients.
The DI332-Q2 and DI338-Q2 comparisons have been explained in QTR82-002, Addendum II. Those factors affected by the SWC stresses are also equivalent between the DI325-Q2 and DI338-Q2 models: {a) Spacing between input circuits is the same, {b} Components directly exposed to SWC transients are the same, (c} Functional and fail-safe criteria are the same, isolation between input and output circuits is maintained.
Validyne has concluded that the comparisons of all SWC-significant characteristics are sufficient to warrant designation of both DI338-XXX-Q2 and BA332-1829-Q2 modules as complying with the IEEE STD 472-1974 requirements.
- Other modules are contained within the Remote Multiplexer unit, but are not normally exposed to the SWC transients "seen" by the signal conditioner units. Validyne does not envision a need to qualify these modules to the SWC requirements.
The modules to be exempted from SWC qualification .are: AB295-Q2, containing 9860-XXX-Q2 plug-ins AD296-l-Q2 AD296-2-Q2 NUMBER QTR82-003 Addendum I SHEET 1 OF 8626 WILBUR AVENUE
