7.2 Device description
Time relays are used for different control tasks in automatic production lines
and for processing machines.
They are suitable for all time-delayed switching operations in control, star-
ting, protective, and regulating circuits and ensure high repeatability of the
set run times.
7.2.1 Device types
Device types
The SIMIREL 3RP1 time relays are available in the following forms:
• Single-function devices, such as the on-delay function
• Multifunctional devices
Frame sizes
The SIMIREL 3RP1 time relays are available in two widths:
•3RP10: 45 mm
The width, height, and depth of time relays and contactors of frame size S00
(3RT/3RH10) are identical. The terminals are therefore on the same level,
and the tier spacing in the cubicle can be kept correspondingly low.
• 3RP15: 22.5 mm
Time relays with 1 changeover contact are 82 mm in height and have six
possible terminals
Time relays with 2 changeover contacts are 102 mm in height and have a
possible twelve terminals
