The T function block on easy800-SWD from device version 01 and on the
easy800 standard from device version 04 has the additional modes Off-
delayed with retriggering and Random switching.
With this timing relay you change the switch time and the on and off time of
a switch contact. The adjustable delay times are between 50 ms and 99 h
59 min.
An easy800 device allows the use of up to 32 timing relays.
