摘要： A method of monitoring an analog signal output from a sensor comprising comparing the amplitude of the analog signal to a first high and low threshold, setting a primary monitoring signal to a first value when the amplitude of the analog signal exceeds the first high threshold, setting the primary monitoring signal to a second value when the amplitude of the analog signal decreases below the first low threshold, comparing the amplitude of the analog signal to a second high and low threshold, setting a secondary monitoring signal to a first value when the amplitude of the analog signal exceeds the second high threshold, setting the secondary monitoring signal to a second value when the amplitude of the analog signal decreases below the second low threshold, comparing the primary and secondary monitoring signals and determining from the comparison whether an error exists with the monitoring of the analog signal.

摘要： The present invention includes a contact block for a safety switch that has a support structure and a pair of electrical contacts that are fixed in position on the support structure. The contact block includes a contact block plunger provided with a bridging contact. The bridging contact extends through the contact block plunger, from one side to another, and protrudes from the sides of the contact block plunger. The contact block plunger is moveable in-between the fixed pair of electrical contacts to move the bridging contacts into and out of contact with the fixed pair of electrical contacts. A contact block guide extends along the support structure and between the pair of fixed electrical contacts and cooperates with the contact block plunger such that the contact block plunger is restricted to movement along the contact block guide.

摘要： A safety switch assembly having a handle pivotably attached to a casing to allow selective operation of an electrical contact assembly. The handle is attached to the casing with a movable pivot such that excessive grip pressure renders the safety switch inoperable until the safety switch is reset. The handle is moveable responsive to grip pressures that range from no actuation to a first grip pressure. Actuation of the handle in this range controls operation of the electrical contact assembly. Gripping of the switch with a grip pressure greater than the first grip pressure moves the pivot such that the safety switch is rendered inoperable, or non-conductive, until manipulation of a reset actuator returns the pivot to a pivot position associated with the first operating zone. Such a construction provides a safety switch that can be rendered inoperable and reset to allow subsequent operation.

摘要： An output module comprises two management units each of which calculates the current demand for the module independently from one another. One management unit controls an output current, controller whilst the other unit monitors the current produced by the output current controller against an independently calculated demand. The output module has multiple output modules. In normal operation, each module provides a portion of the required output current, the total output current being equal to the sum of the currents output by each module. in the event of failure on one of the, modules, the other module or modules switch to providing the total current required and the failed module is switched to a fail safe mode by using an isolation circuit to switch off the output current from that module.

摘要： This invention relates to an apparatus and method for output current control in an Industrial Process Control System, The output module comprises two management units each of which calculates the current demand for the module independently from one another. One management unit controls an output current controller whilst the other unit monitors the current produced by the output current controller against an independently calculated demand. The output module has multiple output modules. However rather than one module providing a backup for the other modules, or alternating between use of each module, in normal operation, each module provides a portion of the required output current, the total output current being equal to the sum of the currents output by each module. In the event of failure on one of the modules, the other module or modules switch to providing the total current required.

摘要： An output module for an Industrial Process Control System that drives a load in a failsafe manner. The output module drives a load in response to a driving signal and includes a controller that generates a command signal and a drive enable signal in response to said driving signal. A keep alive circuit generates an active keep alive signal unless the drive enable signal is inactive. The output module includes a driver circuit that generates a drive signal in accordance with the command signal when the keep alive signal is active such that the load can be driven with a channel failsafe switch in response to the drive signal. The output module can be integrated into any of a number of industrial process control systems to enhance the operability of such systems.

摘要： A lockable safety switch mechanism having a lockable switch mechanism that cooperates in an offset or skewed manner with an electrical switch. The lockable switch mechanism includes a switch plunger that is displaceable along a predetermined axis between a first position and a second position. A contour is formed along the switch plunger and cooperates with one or more locking mechanisms. A fork cooperates with the locking mechanism so as to selectively interfere with free movement of the switch plunger depending on the interaction between the contour and the locking mechanism. A link extends from one of the locking mechanism and the fork and interacts with a plunger of an electrical switch contact carrier so that an axis of movement of the switch plunger can be offset or skewed relative to an axis of movement of the electrical switch plunger.

摘要： A power supply that is capable of supplying power to an input/output channel for an Industrial Process Control System. The power supply includes a primary voltage converter having a first voltage input and a second voltage output, and overvoltage protection components that prevent the second voltage from rising above a predetermined maximum. The power supply includes a first low dropout regulator that is connected to receive the second voltage and to generate a third voltage, a second low dropout regulator that is connected to receive the second voltage and to generate a fourth voltage, and a third low dropout regulator that is connected to receive the fourth voltage and to generate a fifth voltage.
