Search Tips for Time Delay Relays

• Follow the correct format for each family as shown in the examples below, noting that dashes ("-") are used in all Macromatic time delay relays (except 981):

• TR-50222-05
• TR-60222
• SS-6262-06
• SS-40222-05
• TD-78122
• 9816U1

• Use correct prefix: do not confuse the "SS" prefix used on some of our products with "33" or "55" or "88".
• Follow these suggestions for products with modifications:

• Fixed time delay: replace the normal two digit suffix with "F" followed by fixed time delay, i.e., TR-50222-F5S, SS-6262-F1M, etc.
• Remote adjustment: add the appropriate "R" suffix, i.e., TR-50222-05R5, TR-51622-08R3, etc.
• Special trigger switch configuration: add the appropriate "T" suffix, i.e., TR-51622-05T9, TR-51528-08T2, etc.
• Repeat cycle time delay relays with different ON & OFF times: TR-53122-05-12

• If you do not know the complete Product Number, try using the Product Series drop-down menu.  NOTE: search results from the Product Series drop-down menu do not include standard modifications such as fixed time delay, remote adjustment, special trigger configuration & repeat cycle time delay relays with different ON & OFF times--these will only be included if entered as a complete Product Number in the search box.
• Any Macromatic Product Number ending with a letter followed by three numbers, i.e., "C-135" or "D-779", is a custom product and is not included in this database. Contact Macromatic for additional information.
