SIRIUS 3RP25 Timing Relays, 17.5 mm and 22.5 mm Siemens

Область применения



Timing relays are used in control, starting, and protective circuits for all switching operations involving time delays. They guarantee a high level of functionality and a high repeat accuracy of timer settings.

Enclosure version

All timing relays are suitable for snap-on mounting onto TH 35 standard mounting rails according to IEC 60715 or for screw fixing.

SIRIUS 3RP25 timing relays

SIRIUS 3RP25 electronic timing relays for general use in control systems and machine building with:

  • 1 or 2 CO contacts, 1 NO contact (semiconductor) or 3 NO contacts
  • Mono- or multifunctional
  • Combination voltage
  • Wide voltage range
  • Single or selectable time setting ranges
  • Switch position indication and voltage indication by LED

Standards

The timing relays comply with:

  • IEC 60721-3-3 “Ambient conditions”
  • IEC 61812-1/DIN VDE 0435 Part 2021 "Specified time relays for industrial use"
  • IEC 61000-6-2, IEC 61000-6-3 and EN 61000-6-4 "Electromagnetic compatibility"
  • IEC 60947-5-1 "Low-voltage switchgear and controlgear"​

Multifunctional timing relay 3RP2505

The functions of the multifunctional timing relay 3RP2505 can be set by means of the function selector switch. The choice of whether both changeover contacts perform simultaneous delayed switching, or whether one switches with a delay and one switches instantaneously, as well as the selected timing range, is made using the time setting range selector switch. The precise operating time can be set using the operating time switch.

The timing relay can be clearly labeled with the selectable functions using a set of labels. This is included in the scope of supply of the multifunctional relay.

The same potential must be applied to terminals A. and B. For functions, see function diagrams.

Note:

The activation of loads parallel to the start input is permissible when using AC control voltage (see circuit diagram).
