Data Bus In Line Relay Couplers:
Commuting Without Mismatching

Axon’ has developed in line relay couplers to switch bus lines or stub lines. They are designed for applications which require to allow for an automatic disconnection of a number of equipment from the network without affecting the other remote terminals already connected. This is the case when a ground test bench is connected to an aircraft or in the case of applications which need to simultaneously disconnect a group of devices (a satellite, a rocket or a missile). In line relay couplers are in compliance with the MIL-STD-1553 standard.

  • Improved EMI performance
  • Impedance of 77 ohms of bus line terminators is maintained while the network is intentionally cut at a predefined point of the system
  • Transmission of the signal without distortion
  • Relay couplers can switch the signal to another line or a particular device
  • Relay couplers can be connected to classic couplers with the help of splices or ACB1 connectors.
  • Axon’ Cable offers 2 kinds of relay couplers:

    • Inline relay switch coupler (AMB/A-RE-A): to commute simultaneously 1 or 2 bus lines to 1 or 2 different bus lines with a single command signal.
    • In-line relay couplers (AMB/A-RE-C, AMB/A-RE-D) to commute without mismatching.
  • Dependent on the type, in line relay couplers meet the following specifications: JN 1161, MIL-PRF-39016, MIL-R-39016, MIL-STD-810D, MIL-S-19500, MIL-STD-1553.
