Electronic Timers and Interface Modules

The following accessories require use of cabling accessories (LAD4BB●●) for proper mounting. See TeSys N Cabling for illustration.

The solid-state Electronic Serial Timer Modules in Electronic Serial Timer Modules delay the energizing of the contactor coil, and feature built-in varistor surge suppression.

The Interface Modules in Interface Modules allow the contactor coils to be energized from low voltage and low current level signals. They come in mechanical relay and solid-state versions. The relay plus manual operation versions include a lever for manually turning the contactor on and off. When a module receives a low-level signal, it allows the separate-sourced control voltage to flow to the contactor coil. It saves space and wiring time compared to conventional interposing relays.

Footnotes

  1. For spring terminal versions of these blocks, add a 3 to the end of the catalog number (for example, LADN223).
  2. Including 1 N.O. + 1 N.C. make-before-break overlapping contacts.
  3. 1 block may be added to the left side of Size 00–1, AC coils only; only 1 block may be added to either side of the Size 2 contactor, AC coil only. Cannot be installed on Size 00–2 contactors with DC coils.
  4. Device comes with 4 ground terminal points.
  5. For spring terminal versions of these blocks, add a 3 to the end of the catalog number (for example, LADT23). There is no charge for this modification.
  6. Scale range is expanded between 0.1 and 0.6 seconds on the dial for more accurate settings at the lower end of the range.
  7. Switching time between the opening of the N.C. contact and the closing of the N.O. contact: 40 ms ± 15 ms .
  8. Complete the catalog number by adding the coil voltage code (for example, LAD6K10F).
  9. Does not include internal coil clearing contact.
  10. DC available at 24 V only.
  11. Kit including mechanical interlock and wiring.
  12. Kit combines both LAD4CM and LA9D65A69
  13. Installing the suppressor into the cavity makes the electrical connection. The overall width of the contactor remains the same.
  14. For Size 00–2 with DC coils, 3-pole contactors are fitted with built-in bidirectional diode suppression as standard.
  15. Adapter required. See Cabling Accessories.
  16. The mounting hardware (screws, washers, and nuts) comes with the contactors, not the lugs. Starters Sizes 3–7 come with lugs.
  17. Lug kits incude 6 lugs.
