The logic relay provides 16 timing relays from T 1 to T 16.
A timing relay is used to change the switching duration and
the make and break times of a switching contact. The delay
times can be configured between 2 ms and 99 h 59 min. You
can use positive values, values of analog inputs, actual
values of counter relays and timing relays.
You can also use the logic relay as a multi-function relay in
the application. The logic relay is more flexible than any
hardwired timing relay since you can wire all the functions at
the push of a button as well as program additional functions.
h The timing relays of CL-LSR/CL-LST and CL-LMR/CL-LMT
function in the same way as the timing relays of the
AC010 devices.
Exception: The "flasher" function starts on the CL-LSR/
CL-LST and CL-LMR/CL-LMT with the pulse. With the
AC010, the "flasher" function starts with the pause. If
required, the same timing relays can also be used for
retentive data.
You integrate a timing relay into your circuit in the form of a
contact and coil.

To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram.
