Relays / Switches - MIL-STD-1553

Benefits of relay usage in systems

  • Remotely controlled with 5 or 28 volt signal through D-sub connector (DPDT, DPST, Latching)

  • Can effectively terminate a bus or segment

  • Switch data acquisition or bus mon

Optional features

  • Relay switching between three or four buses or stubs (RT’s)

  • Physical configuration

  • Inline relays (configured as an inline coupler; various physical sizes available

  • Any connectors attached

  • Internally terminated 

  • High isolation between outputs is available

The Data Bus relay/switches family of products are typically used to switch MIL-STD 1553 signals between Bus A and Bus B. The switching is accomplished without the interruption of databus protocol.


The DBPR2000 series can switch a UUT from one bus to another (typically A to B) with switching to as many as four buses possible. The device is also used to segment an existing bus into smaller sections. This is useful when adding/removing 1760 stores management systems devices to the bus.


The DBPR1000 is used to shorten an existing bus at some "break point". It will switch to an off position without creating an open circuit impedance.


The DBPR1000T is used to shorten an existing bus by sending the signal to a terminated position.
