MIL-STD-1553 to Relay Output
Part Number: YED/1553/R1/VF1
This MIL-STD-1553 to Relay Output converter extracts a discrete or
a field from a 1553 data word contained in a specified 1553 message. The 1553 data word to be converted
should be specified by you when requesting a quote.
The MIL-STD-1553 to Relay Output converter is powered from an external 28 VDC (18-36V) nominal supply with
internal current and thermal (102 șC) fuse.
The inputs are also reverse polarity protected.
The range and limits of the required
parameter that will switch the relay discrete output must be specified as part
of the requirements for this converter. For example, a 1553 data
word containing "Fuel quantity" or "Ground Speed" could be programmed such that
when this parameter drops to a predefined value the relay discrete is switched.
The switched relay output can be either configured for chassis ground or be
provided as a "volt-free" contact. The discrete output can switch back again
once the parameter increases above the predefined limit. Indicator and/or
enunciator can be provided as an option.
Other options including extra contact outputs, etc. can be specified with the
other requirements at the time of ordering.
The connections for the YED/429/R1/VF1 Adapter are via a D9 filtered plug as
follows:
