摘要： An industrial automation controller module includes a main module and an energy storage module (ESM) releasably connected to the main module. The ESM includes a back-up electrical power source such as a battery or a capacitor that is electrically connected to processor circuitry of the main module when the ESM is physically connected to the main module. In case of interruption of operating power to the processor circuitry of the main module, the back-up power source of the ESM supplies back-up power to the main module to allow for completion of an emergency save operation to save data to non-volatile memory in the main module. If the ESM includes a capacitor back-up power source, it is charged by the main module and the capacitor charge is dissipated if the ESM is separated from the main module. In all cases, the ESM can include one or more configuration parameters stored therein that allow the main module to validate (or not) the ESM for the requirements of the main module, with respect to type of back-up power source, product code or model, capacity of back-up power source, and the like. The main module can also initiate periodic testing of the back-up power source of the ESM.

摘要： An output circuit has multi-stage protection circuitry for protecting against different fault current conditions. The protection circuitry operates by detecting voltage changes across the output transistor of the output circuit. The output circuit comprises first, second and third switching devices. The first switching device is connected to the output device and power conditions the output signal. The second and third switching devices override the output signal and turn off the first switching device when a magnitude of current through the first switching device exceeds predetermined magnitudes for predetermined amounts of time. A protection circuit is also disclosed which has a sensing device that senses a current flow condition by sensing a voltage drop produced across two terminals of the first power conditioning transistor, the two terminals being the terminals through which the current flows. Advantageously, the output circuit utilizes highly flexible two-stage protection circuitry. The protection circuitry separately identifies surge current and overcurrent conditions. In addition to the flexibility provided by the use of two-stage protection circuitry, flexibility is also provided by the fact that component values may be easily varied to vary the magnitudes/durations of current within each stage which activate the protection circuitry. Moreover, the protection circuitry has a very fast response time. As a result, an output transistor which is protected by the protection circuitry of the present invention suffers much less stress in the event of a short circuit condition.

摘要： A connector assembly uses an intermediate guide plate to align and mate opposing connectors mounted on electrical chassis. The intermediate plate includes guide pins and is aligned to the first chassis by means of an alignment fixture attaching between the guide pins and the first connector. The guide plate is attached to the first chassis and the alignment fixture is removed, the guide pins allowing alignment with the second chassis and connector.
