20090125156 | ENERGY STORAGE MODULE - 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. | 05-14-2009 |
20100320990 | Low Heat Dissipation I/O Module Using Direct Drive Buck Converter - A current-loop output circuit for an industrial controller provides for low power dissipation and reduced part count by driving current loads of different resistances directly from a switched voltage source. Proper filtering and design of a feedback loop allows the necessary transient response times to be obtained. | 12-23-2010 |
20140145638 | Circuit That Deciphers Between AC and DC Input Signals - Electronic devices require correct power in order to operate correctly. Receiving an incorrect power signal could potentially result in immediate and/or long term harm to the electronic device and/or catastrophic conditions. Certain devices, such as programmable logic controller (“PLC”) modules, may provide variable power to electronic devices, such as field devices comprising sensors and/or actuators. The present inventors have recognized that deciphering between AC and DC input signals before coupling electronic devices to such power sources may advantageously avoid harmful and/or catastrophic conditions. Aspects of the present invention provide an electronic circuit for deciphering between an AC and a DC input signal. Systems and methods are also described. | 05-29-2014 |
20140306691 | Circuit That Deciphers Between AC And DC Input Signals - Aspects of the present invention provide a module including an electronic circuit that flags the presence of AC or DC input signals. An AC filter receives an input signal and couples it to a first leg. The AC filter permits an AC signal to pass to produce a first output and prevents a DC signal from passing. A DC filter also receives the input signal and couples it to a second leg. The DC filter permits a DC signal to pass to produce a second output and prevents at least part of an AC signal from passing. A lock out circuit in the first leg prevents the second leg from producing the second output when the first leg produces the first output. The output of each leg may be digitized and coupled to a logic controller to flag the presence of AC or DC input signals. | 10-16-2014 |
