This module, named “6TL-MMI”, is designed to be the interface between an operator and a SYSTEM as well as being a metered power distribution unit (PDU) for it. The module is providing also safety controls, data bus interfaces, temperature control and timers.

The 6TL-MMI is suitable for any ATE, and specially for those based on CAN bus controlled devices, because in addition to the above functionalities, this module is also providing galvanic isolation up to 1500V for the CAN bus. This isolation will block potential disturbance towards the DUT.

The 6TL-MMI is powered from the grid through a bipolar switch for providing power to the Un-switched bus, and through an emergency stop with safety relays to provide power to the Switched bus.

The Switched bus is used to provide energy to the DUT as well as to all the power supplies that will be used to power up the DUT. The Un-switched bus (Two 10A Schuko plugs) is used for powering the control computer through a UPS.

The module includes a universal input DC power supply of 24VDC 8,3A with a thermal fan control. The 24VDC power outputs could be interrupted for energy saving while the system is in Stand-by mode or for resetting the modules.

The 6TL-MMI can be also used by the SYSTEM operator to choose options through the executive SW, or for starting/terminating the test execution.

Concerning the safety, note that a photoelectric barrier could be installed as part of the safety chain of the SYSTEM, as the 6TL-MMI provides power supply and automatic test and reset for it. Eight floating contacts (Potential free) are available for enabling external devices, that will also be part of the safety circuitry.
