3 Contact us at: ; Introduction Siemens offers 3RP15 electronic timers which meet the various control timing requirements of industry. These timers comply with IEC IEC /EN (EMC) Carry CE marking Range ON delay: Control supply voltage options Universal voltage of to 0V ac/dc Time ranges sec, sec Universal time range of 0.05 sec to 100Hr OFF delay: Control supply voltage options Time ranges sec, sec Star Delta: Control supply voltage options Universal voltages of 200 0V ac/dc, Vac/dc and V ac/dc 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, dditive ON delay) Control supply voltage options Universal voltage of 0V ac/dc Time ranges Universal time range 0.05 sec to 100Hrs pplication 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. 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) 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 deenergised (OFF) state. Start input B1 or B3 must only be triggered when the supply voltage is applied. OFF delay timers are with aux. voltage (refer wiring diagram fig.1). Same potential must be applied to 1 and B1, or 3 and B3. With the twovoltage version, only one voltage range must be connected. The activation of loads parallel to the start input is not permissible when using C control voltage (see diagram below). Fig.1 Mounting 3RP electronic timers are suitable for snap mounting onto 35 mm standard DIN rails. ccessory for mounting 3RP timers on base plate is available and can be ordered separately. Layout Benefits Reduction in inventory cost (upto 80%) due to universal time and universal voltage ON delay timers. High accuracy (<±1% repeat accuracy & <±5% setting accuracy) and switching reliability. High mechanical endurance of 30x10 6 operations ensures trouble free operation Integral surge suppression No voltage surges during switching makes them ideal for use with electronic circuits Clear visual status indication through 2 separate LEDs both for actuation of control supply and the change over status. High level of Electromagnetic compatibility (EMC) i.e. maximum immunity to interferences. No more failures of contactors in Star Delta starting during changeover LED to indicate time relay energised LED to indicate relay switched Dial for selecting time setting range Function selector switch (Multifunction) Device designation label Dial for selecting operating time Display window for selected time setting range Display window for set function 2
