Programmable integrated detonator delay circuit.

摘要

In the control process, the programming unit (18), once the programming of ignition modules has taken place, transmits the likewise programmed delay times to the firing control unit (17). The firing control unit (17) can simultaneously interrogate the ignition modules (15) which return the required information to it. The coded firing control assembly and the coded ignition modules make it possible to carry out the process. <IMAGE>
