We have been supplying a wide range of Siemens Products to Various Industries, through our Work, we have built a reputation as a company that combines innovation with integrity with quality range.
ELECTRONIC TIMER
Whether on-delayed, off-delayed or timing relay for switching from star to wye-delta - with diverse designs, our broad range covers almost every application. All of our timing relays are especially compact and are available with removable terminal, screw connection or spring loaded technology. An additional advantage: Versions with wide-range voltage of AC/DC 24 to 240 V reduce the number of versions and thus warehousing. 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. Changing the time setting ranges and the functions will only be effective when carried out in de-energised (OFF) state. Start input B1 or B3 must only be triggered when the supply voltage is applied. With the two-voltage version, only one voltage range must be connected.
