Switch-on and switch-off delay

Devices for switch-on and switch-off delay of signals are used to protect machines and installations from damage caused by premature switch-on or switch-off. A typical example is the protection of a vessel against overflow or dry running.
The device receives signals from an external sensor and switches its outputs according to the adjustable input and output delays. Optionally, ON delay and/or OFF delay, ON pulse and OFF pulse can be set via a selector switch.
