| Differences Between the Obsolete SS-5 & SS-6 Series of Time Delay Relays vs. Current TR-5 & TR-6 Series |
| Issue |
| I have an old SS series of product which appears to be obsolete and was told to replace it with a TR series equivalent. What is the difference between the old & new products? |
| Solution/Resolution |
| The SS-5 Series and SS-6 Series of plug-in time delay relays were manufactured by Macromatic through the summer of 1999. At that time, they were replaced by the TR-5 & TR-6 Series, the next generation of Macromatic plug-in time delay relays. All TR Series products are direct replacements for their SS Series equivalent in terms of form, fit & function. The major obvious difference is the white enclosure of the TR Series products vs. the black enclosure of the obsolete SS Series. However, there are many more improvements which are summarized on this page --click for more information. Or contact Macromatic if you have other questions about the substitution of the TR Series for the SS Series products. |
