dry contact Explanation: I think you right. I had agreed to Dustys' answer prematurely bcause I had this term in a manual of Japanese origine to denote a NC *output*. However, reading your text again my impression is that you have an *input*, i.e. the signal in question is used to control the instrument, not to control an external device. If this understanding is correct, dry contact (or potential-free contact) is the correct term. -------------------------------------------------- Note added at 12 hrs 12 mins (2003-12-01 16:44:54 GMT) -------------------------------------------------- Hmm, where did my previous note go???? Anyhow, it\'s a question of perspective. What it boils down to is this question: Does the specification (no-voltage) refer to the signal to be applied to the input (output of whatever device controlling this signal) or does is no-voltage a property of the input? As the phrase is \"no-voltage contact signal\" I tend to think it refers to the signal. Hence, the *signal* has to be a contact signal, i.e. coming from a potential-free contact. Which means there is actually a voltage (however small) to detect the input state. Whenever the contact is closed (e.g. by a relay in the external device that lost power), the resulting change triggers the action. In other words, if the phrase appears in the specifications of the UPS, I tend to think that I\'m likely to be correct. -------------------------------------------------- Note added at 12 hrs 22 mins (2003-12-01 16:55:07 GMT) -------------------------------------------------- No matter what the contact turns out to be, it\'s nice to see teamwork in progress. Thanks for that. |
