About the IS220PPROH1A
This IS220PPROH1A printed circuit board product offering from General Electric is an interesting product within the trusted automated industrial retailer's greater Mark VI Turbine Control System Series, firstly for the fact that it does not exist as a standard printed circuit board product at all but as a special modular assembly product. The Mark VI Turbine Control System Series that this IS220PPROH1A modular assembly product in particular belongs to has a set of specific functional applications in gas, steam, and wind turbine automated drive assembly control and management systems. While this is the case, this IS220PPROH1A product's greater Mark VI Series's set of specific possible functional applications can be seen as a major upgrade on the Mark V Series's applications that came before, as this product series' potential applications have been restricted to gas and steam turbine assemblies alone. This IS220PPROH1A product's Mark VI Series' nature as one of the final-developed GE Mark product series to incorporate the patented Speedtronic control system technology across many offerings is an additional reason why it is considered one of the most esteemed GE Mark product series on its current automated industrial promotional marketplace.
Hardware Tips and Specifications
The IS220PPROH1A is a Turbine specific I/O module. It is designed to provide a direct interface to specific turbine field devices. This setup eliminates or reduces much of the previously needed instrumentation needed to make the connection to field devices, and also improves running reliability and reduces long term maintenance. The IS220PPROH1A typically works with the TREAH_A terminal board and is used in Aeroderivative Turbine Emergency trip applications. The component can connect to either barrier or box type terminal blocks. The IS220PPROH1A has field wiring restrictions for voltage sensing that limits cable length to 1,000 feet of 18 AWG wiring. It is important to note the IS220PPROH1A cannot be auto-reconfigured when swapping a BPPB P-Pack with a BPPC P-Pack. The IS220PPROH1A is built with a front faceplate that is marked with the component id number and several LED indicators. These are placed on the front faceplate in pairs. The first pair is labeled PWR/ATTN, the second LINK/TxRx and ENET 1, and the third LINK/TxRx and ENET2. A final component is located at the bottom of the faceplate; this is labeled IR Port. The IS220PPROH1A accepts three speed signals. This includes deceleration, acceleration, and overspeed. The component also has hardware implemented overspeed. This IS220PPROH1A product is actually not the originally-developed product of its specific Mark VI Series functionality, as that would be the IS220PPROH1 parent PCB notably missing this IS220PPROH1A product's A-rated functional product revision.
The pack monitors the status and operation of selected trip boards through a set of comprehensive feedback signals. The pack supports TMR and simplex back up protection. The IS220PPROH1A is built with a high speed processor and two fully independent 10/100 Ethernet ports. The pack has a hardware reset circuit and watchdog timer. Temperature is monitored by an internal sensor. This IS220PPROH1A product in particular is not surrounded by any great amount of originally-pertinent instructional manual materials; probably a result of General Electric's concerted efforts to remove copyrighted material from infringing sources online. With this being the case, the IS220PPROH1A functional product number itself identifies a number of relevant IS220PPROH1A Board hardware specifications through its series of specially-designed functional naming components. For example, the IS220PPROH1A functional product number is started through the dual-functional IS220 series tag responsible for identifying this IS220PPROH1A product's special modular Mark VI Series assembly version as well as its domestic original manufacture location. Some of the other relevant hardware specifications revealed in this manner include the IS220PPROH1A Board's PPRO functional acronym on top of its conformal PCB coating, group one Mark VI Series product grouping, and its A-rated functional product revision.
