3RP2505 multifunctional timing relay

Setting the functions on the device

The functions of the 3RP2505 multifunctional timing relay can be set by means of the function selector switch. Whether both CO contacts are switched in parallel or one CO contact with a delay and one instantaneously and the choice of time setting range are set by means of 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.

Note:

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

Overview of functions

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.

Особенности

Simple inventory management and logistics thanks to low device variance
Less space required in the control cabinet thanks to 17.5 mm und 22 mm wide versions
Consistent in all functions due to wide voltage range from 12 to 240 V AC/DC
Up to 27 functions according to IEC 61812 in the multifunctional timing relay with wide voltage range
Multifunctional timing relay with semiconductor output for high switching frequencies, bounce-free and wear-free switching

Standards and approvals

IEC 60721-3-3 "Classification of environmental conditions"
IEC 61812-1/DIN VDE 0435 Part 2021 "Specified time relays for industrial use"
IEC 61000-6-2, IEC 61000-6-3 and IEC 61000-6-4 "Electromagnetic compatibility"
