Answers for industry.

Introduction Siemens offers 3RP15 electronic timers which meet the various control timing requirements of industry. These timers comply with IEC 60 947-5-1 IEC 61 000-6-2/EN 50 081-1 (EMC) Carry CE marking

• Sleek 22.5mm wide housing and compact design saves panel space. Thus 3RP timers ensure unmatched reliability and offer excellent ‘Value for Money’

Note • Changing the time setting ranges and the functions will only be effective when carried out in de-energised (OFF) state.

Range

• Start input B1 or B3 must only be triggered when the supply voltage is applied.

ON delay:

Control supply voltage options Discrete voltages Universal voltage of 24 to 240V ac/dc



Time ranges - 0.5 -10 sec, 5 - 100 sec Universal time range of 0.05 sec to 100Hr

• OFF delay timers are with aux. voltage (refer wiring diagram fig.1). Same potential must be applied to A1 and B1, or A3 and B3.

OFF delay:

Control supply voltage options Discrete voltages

• With the two-voltage version, only one voltage range must be connected.



Time ranges - 0.5 - 10 sec, 5 - 100 sec

Star Delta:

Control supply voltage options Discrete voltages Universal voltages of 200 - 240V ac/dc, 380 ‑ 440Vac/dc and 230 - 400V ac/dc

• The activation of loads parallel to the start input is not permissible when using AC control voltage (see diagram below).



Time ranges - 1- 20 Sec, 3 - 60 Sec with 50 msec changeover delay

Multifunction: 1 timer 8 functions (ON delay, OFF delay, ON+OFF delay, Cyclic, Make Contact, Break contact, Pulse shaping, Additive ON delay)

Control supply voltage options Universal voltage of 24 - 240V ac/dc



Time ranges - Universal time range - 0.05 sec to 100Hrs

Application

Mounting

3RP15 electronic timers can be used for all delayed switching applications in control, starting and protection circuits. They are ideal for use in application like machine tools, material handling, process control and motor control.

3RP electronic timers are suitable for snap mounting onto 35 mm standard DIN rails. Accessory for mounting 3RP timers on base plate is available and can be ordered separately.

With multifunction timer, you can configure the same timer as per your application need. Thus one timer is suited for many applications (refer timing diagram)

Benefits • Reduction in inventory cost (upto 80%) due to universal time and universal voltage ON delay timers.

Layout

LED to indicate time relay energised

• High accuracy (<±1% repeat accuracy & <±5% setting accuracy) and switching reliability.

LED to indicate relay switched

• High mechanical endurance of 30x106 operations ensures trouble free operation

Dial for selecting time setting range

• Integral surge suppression – No voltage surges during switching makes them ideal for use with electronic circuits

Function selector switch (Multifunction)

• Clear visual status indication through 2 separate LEDs both for actuation of control supply and the change over status.

Device designation label

• High level of Electromagnetic compatibility (EMC) i.e. maximum immunity to interferences. • No more failures of contactors in Star Delta starting during changeover
