Expand Testing Capabilities with the HD Logic I/O Module
In today’s power industry, testing protection and control (P&C) systems is more complex than ever. Field engineers are tasked with ensuring P&C reliability amid a growing presence of intermittent power sources from inverter-based wind and solar renewables and heavy loading on utility and industrial electrical infrastructures. Knowing how quickly, or if, relays will initiate circuit breaker operations is critical, especially in complex automated schemes that rely on real time communication and control functions to prevent electrical damage to vital system assets.
With so much on the line, relay commissioning and routine maintenance today demands advanced test instruments with extremely accurate input and output (I/O) sensing. The cutting-edge platform of modular F8-series Power System Simulators from Doble meet that requirement with the HD Logic I/O Module, a state-of-the-art component that precisely measures response characteristics during tests of protection and secondary system devices.
Clever Connections
As an F8 module, the ports of the HD Logic I/O Module feature color-programmable LED rings. Doble’s Protection Suite and RTS software apply color selections to the HD Logic I/O Module for custom indications of expected test lead placements and input signal detection. If sensing issues, the HD Logic I/O Module displays red LEDs and the F8 test set emits an alarm tone. These visual and auditory aids provide technicians with feedback so that they can avoid errors in their test setup and work safely and efficiently should troubleshooting be necessary.
Other innovations are its dual-socket ports and special dual-pin adapter cables. By design, the unique dual-socket/dual-pin connectivity affords the HD (high density) Logic I/O Module twice the programmable I/O pairs as the LD (low density) Logic I/O Module in standard F8 module dimensions. Plus, polarity-based contact monitoring is supported where positive and negative voltage differentials can be detected in a single connection. Overall, the HD Logic I/O Module design not only offers more I/O but ingeniously can require fewer connections as well, an advantage when using F8200 or F8300 Power System Simulators for end-to-end testing and other applications involving complex relay response monitoring.
Versatility
Each of the eight inputs of the HD Logic I/O Module can be utilized for counting and measuring 33 kHz electrical pulses up to 40 V. Additionally, Port 8 provides dedicated inputs that can measure DC in ranges up to 10 V / 20 mA.
These capabilities enable accurate transducer and Class 2 meter tests, showcasing another application of the HD Logic I/O Module for device testing that eliminates any need for separate equipment.
Expands F8 Flexibility
The F8 platform is designed with configurability at its core, allowing users to customize F8200 and F8300 Power System Simulators to meet evolving testing requirements. The HD Logic I/O Module seamlessly integrates into this platform, adding advanced capabilities while ensuring compatibility with other F8 modules as well as Protection Suite and RTS software.
With an expanded set of I/O and advanced features in single connections, the HD Logic I/O Module has ample capacity to streamline test setup for a variety of test and measurement applications. Including this module in an
F8 equipment fleet ensures F8200 and F8300 instruments remain relevant and capable long term despite evolving complexity in P&C testing.
