    Relay Insulation: Microsemi BR246-S0233 - Why Resistance Changes?

    To berkeman: I'm terribly sorry but I'm not sure what you meant as "Do both sides of the questionable relay behave the same?". both sides meaning A-side and B-side? And yes, I would like to open it up to see what's going on. The unfortunate thing is, there is only one "defective" relay and 9...

    Relay Insulation: Microsemi BR246-S0233 - Why Resistance Changes?

    To berkeman: No, I didn’t buy them from eBay. Bought them from the franchises distributor. They are not brand new though, 5 are date code 1638 and another 5 is 1362. The 5Mohm one is date code 1638. They’ve never been used so I figuered that the risk of any insulation material degradation is...

    Relay Insulation: Microsemi BR246-S0233 - Why Resistance Changes?

    To Rive: No, I don't keep it in my hand. it's placed on a desk. To CWatters: Yes I agree that it's very high resistance and I was concerned about the accuracy of my reading. The issue is, I have 9/10 of these that ranges from 300Mohm - 500Mohm even after power up, and only one that resistance...

    Relay Insulation: Microsemi BR246-S0233 - Why Resistance Changes?

    I have Microsemi BR246-S0233. As is, the resistance between the X2 (GND) and signal line (e.g. A2) is OL. However, when I power it up (X1 = 25VDC), leave it for 5 minutes and power off, then straight away measure the resistance between X2 (GND) and the signal line A2, the resistance is now...
