BIS-419 relay has two switching sections and allows for switching of two lightning circuits or others receivers from several different points and in accordance with the preselected sequence.
OperationThe relay power supply is indicated by a green LED U. Sequential relay has two separate outputs: R1 and R2. Contact status (closed/open) is forced sequentially in accordance with a predetermined program. Contacts switch to another state after subsequent pulse from control button. R1 and R2 contact activation is indicated by the relevant R1 and R2 red LED. After a power failure, contact state is reset. When the power is back on, the relay starts from the sequence number 0.
Note!BIS-419 230 V can be used with backlit buttons.
Working function
Function A
Pressing the button subsequently repeats sequences 0-3.
Function B
* Pressing the button subsequently in less than 5 seconds repeats sequences of 1-3.* Subsequent pressing of the button after more than 5 seconds disconnects both contacts (sequence 0).* Long press – in any sequence – disconnects both contacts (sequence 0).* Pressing the button after both relays were turned off restores the last state (memory of state). Does not apply in the case of a relay power failure.
Function C
Pressing the button subsequently repeats sequences 0-3.
Function D
* Pressing the button subsequently in less than 5 seconds repeats sequences of 1-3.* Subsequent pressing of the button after more than 5 seconds disconnects both contacts (sequence 0).* Long press – in any sequence – disconnects both contacts (sequence 0).* Pressing the button after both relays were turned off restores the last state (memory of state). Does not apply in the case of a relay power failure.

These data are indicative and will heavily depend on the design of a specific receiver (that is especially important for LED bulbs, energy-saving lamps, electronic transformers and pulse power supply units), switching frequency and operating conditions.
