TeSys™ D IEC Style Instantaneous Control Relays

CAD32

These 600 V relays are approved for use around the world. TeSys D relays are usually mounted on 35 mm DIN track, but can also be mounted directly to a panel. The contacts have NEMA A600 and Q600 ratings, in addition to the standard IEC ratings, making them suitable for use in most any control circuit. Low consumption versions are available for use with low level DC control signals from a computer or a PLC. Adder decks can be added to a basic five pole relay to make it up to an 11 pole relay. The serrated silver-nickel contacts with wiping action provide excellent reliability in 12 or 24 V control circuits. Special auxiliary contacts are available for switching low power down to 5 V at 10 mA. Timer and mechanical latch attachments are available.

Footnotes

  1. Add the proper voltage code from Coil Voltage Codes or Coil Voltage Codes (cont.):277–600 Vac, 110–440 VdcAdd the proper voltage code to the end of catalog number. to the end of the catalog number. For example, CAD50B7.
  2. Add the proper voltage code to the end of catalog number.
  3. Auxiliary contact blocks with four contacts cannot be used on relays with low consumption coils.
  4. Includes 1 N.O. and 1 N.C. overlapping contact.
  5. Grounding terminal points (2 terminals jumpered together; see diagram on page 8 of Catalog 8501CT0101).
  6. With extended scale from 0.1 to 0.6 s.
  7. With switching time of 40 ms ± 15 ms between opening of the N.C. contact and closing of the N.O. contact.
  8. Power should not be simultaneously applied or maintained to the mechanical latching block and the CAD relay. The duration of the control signal to the mechanical latching block and the CAD relay should be greater than or equal to 100 ms.
  9. Complete the catalog number by adding the coil voltage code from Coil Voltage Codes. For example, LADK10B.
  10. For 24 V operation, the relay must be fitted with a 21 V coil (code Z7).
