Functions
(see diagrams above)
Symmetrical relays: On and Off delay times are equal.
On-delay and Off-delay relay
External control possible for
- partial stop of time delay
- adjustment of time delay (1)
Start control via
external contact only
On-delay and Off-delay relay
Start control via
external contact only
Asymmetrical relays: On and Off delay times are adjusted separately.
On-delay and Off-delay relay
External control possible for
- partial stop of time delay
- adjustment of time delays (1)
Start control via
external contact only
(1) By external potentiometer(s), to be ordered separately. If external potentiometer(s) is/are fitted, the internal
potentiometer(s) is/are automatically disconnected.
(2) A switch on the front face of the relay allows the second changeover contact to be used in instantaneous mode.
