6.1.1.5 T - Timing relay
General
easyE4 base devices provide 32 timing relays (timer)
T01…T32.
You can use a time relay to delay the switching duration and
the ON and OFF times of a switch contact. The times can be
set from a range of 5 ms to 99 h 59 min.
As reference values, you can use positive values,
e.g., from analog inputs or actual values from counter and tim-
ing relays.
Minimum time setting: 0.005 s (5 ms).
Operating principle
Each one of the 32 timing relays is a multifunction relay with various operating modes.
This operating mode is selected during configuration and cannot be changed at runtime.
In addition, the time range can be configured as well. Seconds, minutes, and hours are
available.
The operands with the time reference values are connected to inputs I1, I2 and the
switching state and the actual value of the running timing relay are signaled at the out-
puts.
The timing relay is started via the trigger coil T…EN and can be selectively reset via the
reset coil T…RE. The third coil T..ST terminates the run down of the actual time.
The EN input is used to start and stop the timing relay.
Enabling the function block by disabling the Function block
release by Enable is necessary option is not possible in this
case.
