■
Benefits
•
Easy stock keeping and logistics thanks to low variance
of devices
•
Reduced space requirement in the control cabinet thanks to
variants in width 17.5 mm and 22 mm
•
Consistent for all functions thanks to wide voltage range from
12 to 240 V AC/DC
•
Up to 27 functions according to IEC 61812 in the
multifunctional timing relay with wide voltage range
•
Multifunctional timing relay with semiconductor output for high
switching frequencies, bounce-free and wear-free switching
Standards and approvals
•
IEC 60721-3-3 "Classification of environmental conditions"
•
IEC 61812-1/DIN VDE 0435 Part 2021
"Specified time relays for industrial use"
•
IEC 61000-6-2, IEC 61000-6-3 and

Application
Timing relays are used in control, starting, and protective circuits
for all switching operations involving time delays. They guaran-
tee a high level of functionality and a high repeat accuracy of
timer settings.
Enclosure version
All timing relays are suitable for snap-on mounting onto
TH 35 standard mounting rails according to IEC 60715 or
for screw fixing.
