 Introduction • Sleek 22.5mm wide housing and compact design saves panel
space.
Siemens offers 3RP15 electronic timers which meet the various
control timing requirements of industry. These timers comply with Thus 3RP timers ensure unmatched reliability and offer excellent

Application Mounting
3RP15 electronic timers can be used for all delayed switching 3RP electronic timers are suitable for snap mounting onto 35 mm
applications in control, starting and protection circuits. They are standard DIN rails. Accessory for mounting 3RP timers on base
ideal for use in application like machine tools, material handling, plate is available and can be ordered separately.
process control and motor control.
Layout
With multifunction timer, you can conigure the same timer as
per your application need. Thus one timer is suited for many
applications (refer timing diagram)
