USB controller switches relays for ATE
systems
The USB-M 48 USB controller allows users to control relays (up to 500mA primary current) directly from a PC via a standard USB interface.
The USB-M 48 USB controller allows users to control relays (up to 500mA primary current) directly from a PC via a standard USB interface The relays can be controlled without additional drivers, ie the USB controller's outputs are working as relay drivers and no additional drivers, such as GPIB etc, have to be interconnected

Test card simulates automotive switching
A new PXI card provides switch simulation and state monitoring of digital signals in automotive engineering applications.
Therefore, one USB controller is able to directly control up to 48 relays.
Via an expansion line the USB master controller can control up to two USB slave controllers (USB-S 48).
The user can specifically determine the relay type and its functions due to the required applications.
The USB controller was specifically developed as a control unit of a versatile modular load switching system which can be operated both via USB and digital I/O.
The load switching system comes in a 19in format, and can be used either as a standard component integrated in functional test systems or as a stand-alone unit.
Applications include: switch-in of original or equivalent loads at UUT outputs and inputs; loop-in of shunt resistors into the load circuit to detect load currents; provision of galvanically decoupled control signals for the control of external and internal relays; and building relays matrixes.
Several options allow the modification of the load box to a unit, which not only provides load switches but includes these loads in itself.
A compact device for load simulation is thereby available which can easily be configured by means of the standard load modules.
Besides its use as part of this load switching system, the new USB controller can individually be integrated into existing test systems.
A prerequisite is the existence of a backplane connected to the controller which routes the signals, received from the USB controller, to the controlled modules.
The user can set the load relays' control voltage ranging between 5 and 30V via an external reference input. Request a free brochure from Goepel Electronic ...
