Can we use the impulse relay iTL with maintained signal?
The closing of the impulse relay type iTL is triggered by an impulse on the coil,such as a push button order.
The duration of the control order is 50 ms to 1 s (200 ms recommended),and longer signal will affect the relay lifetime.
Consequently,if the control signal existing is longer than the above mentioned limit,we can advise to use the iTLm type,which Operates by latched orders from a changeover
contact (switch, time switch, thermostat,...).
