TEC Model 156 |
Analog Signal Isolator | ||||
| Environmental and Seismic Qualification | ||||||
|

|||||
|
The TEC Model 156 Series Analog Signal Isolators are qualified to meet
the requirements of IEEE Standards 323-1974, 344-1975, and 381-1977. The qualification
program included baseline functional testing, thermal aging, irradiation aging, seismic
testing, and functional testing after each type test. TEC has performed isolation integrity testing on the Model 156 Isolator. Such testing consisted of the following: (1) Shorts, opens, and 120 V ac at 20 A fault (with input fuses shortened) applied to the non-1E side; and (2) 2000 V dc at 20mA (with input fuses shortened) applied to the non-1E side. The modules are manufactured by TEC under its Quality Assurance Program in accordance with 10CFR Part 50. If additional information is required on the isolation integrity or qualification of the TEC Model 156 Isolator, copies of pertinent reports are available. |
