For the series production of XFEL cryo modules, it is planned to test all complete modules prior the installation in the XFEL tunnel. For the test stands in the Accelerator Module Test Facility (AMTF), we have developed a new technical interlock. The interlock allows the observation of 8 individual analog signals per device (like temperature, pressure, light, free electrons) and can be fully remote controlled. Each channel has its own upper and lower remote controlled thresholds. The channels will be customized with sensor specific module cards, which adapt the power needs and signal conditioning to the specifications of the different sensors. The local display is used as user interface and the little space requirement makes the device quite suitable. An overview of functionality, internal features, connectivity and extendability of the device is given.
