Timers
Multifunction
Timer Type VIMT51CW24
Description & Mode of operation:
Function Dr - Delay on release
The relay operates as soon as the trigger contact is closed.
The time period begins when the trigger contact is opened.
The relay releases at the end of the set delay time or when
the power supply is disconnected. The relay operates again
when the input contact is closed again. If it is opened
before the end of the delay time the relay keeps ON, a new
time period begins as soon as the contact is closed again.
63

mounting on DIN-rail. Housing 17.5 mm wide suitable both
for back and front panel mounting.
Wide power supply range: 12 to 240 VAC/DC.

Function Op - Delay on operate
The time period begins as soon as the trigger contact is
closed.
At the end of the set delay time the relay operates and does
not release until the trigger contact is closed again or the
power supply is disconnected. If the trigger contact is
closed before the end of the delay time, the device resets
and a new time period starts.
Q
Function In - Interval
The relay operates and the time period begins as soon as the
trigger contact is closed. The relay releases at the end of this
period or when the power supply is disconnected. The relay
operates again when the trigger contact is closed again. If the
trigger contact is closed before the end of the delay time, the
device resets and a new time period starts.
Q
Function Io - Interval on trigger open
The relay operates and the time period begins as soon as
the trigger contact is opened. At the end of the set delay or
when the power supply is disconnected the relay releases.
The relay operates again when the trigger contact is opened
again. If the trigger contact is opened before the end of the
delay time the relay keeps ON and a new time period
begins.
Function Id - Double interval
The relay operates and the time period begins as soon as
the trigger contact is closed. The relay releases at the end of
this period or when the power supply is disconnected.
When the trigger contact is opened the relay operates again
for the set delay period. If the trigger contact is opened
before the end of the first time period the second one
begins; if the trigger contact is closed before the end of the
second time period the device resets and the first time period begins again.
Specifications are subject to change without notice (11.01.07)
Function R - Symmetrical recycler, ON-time period first
The relay operates and the time period begins as soon as
the input contact is closed. After the set delay period the
relay releases for the same time period. This sequence continues with equal ON- and OFF-time periods until the power
supply is interrupted.
Function Rb - Symmetrical recycler, OFF-time period first
The time period begins as soon as the input contact is
closed. The relay is OFF during the set delay period, after
this time it operates for the same time period. This
sequence continues with equal OFF- and ON-time periods
until the power supply is interrupted.
Additional Load
It's possible to wire an additional load (i.e. a relay) between
pins Y1 and A2, driven by the trigger contact without damaging the device.
