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.
