Product Description
The IS220PTURH1B printed circuit board is a PCB that was developed by General Electric shell company GE Energy, specifically for use in their Mark VI Speedtronic series of turbine control system products. This PTUR-abbreviated printed circuit board can be more explicitly defined as a Turbine Specific Primary I/O Trip Pack. This I/O Trip Pack is considered a revised PCB, as it exists as a modified version of the preexisting IS220PTURH1 printed circuit board. As indicated through the presence of the "IS220" series tag in the IS220PTURH1B board's individualized product number; this Primary I/O Trip Pack features a special assembly version that should bolster its revised performance specifications
Hardware Tips and Specifications
As with any similar Mark VI Speedtronic Series printed circuit board, this IS220PTURH1B model I/O Trip Pack comes standard with a series of hardware specifications that are specifically important to its overall functioning. This Primary I/O Trip Pack has been allowed for use in various hazardous locations; but only when paired with the IS200TRPAS1A terminal board accessory. When equipping the IS200TRPAS1A terminal board assembly for conjunctive use alongside a PTUR I/O Trip Pack, a series of voltage specifications and best practices are important to remember. For starters, the IS200TRPAS1A terminal board features voltage protection inputs with V dc voltage ratings of 16 V dc at minimum and 140 V dc at maximum voltage capacity. The TRPA-abbreviated terminal board that interfaces with the IS220PTURH1B has an E-stop input voltage range of 18 to 140 V dc and an additional Speed Inputs voltage range of -15 to 15 VDC.
While originally-produced instructional materials for the IS220PTURH1B are certainly helpful in outlining some of the compatible terminal boards that correspond with this Primary I/O Trip Pack, more IS220PTURH1B-specific information can be gleaned from both a thorough visual inspection of the product and a complete part number breakdown of the IS220PTURH1B product number. For starters, a series of LED indicators are immediately evident on the front face of the IS220PTURH1B I/O Trip Pack, all printed with various factory-issue labels, including the Turbine I/O, K25, K25P, PWR, ENET1, ENET2 labels, and many more. Also present on the front face of this IS220PTURH1B product is a singular port, labeled conveniently as an "IR Port." While the front face of this product is crucial to diagnostics of its functionality, this PTUR-abbreviated module features additional crucial hardware components on its back; including dual ethernet ports, and two screw standoffs for installation purposes.
While a visual inspection of the IS220PTURH1B does shed some light into its basic functionality, its series placement and revision history is revealable through a breakdown of the individualized IS220PTURH1B product part number. The "IS220" tag present at the very beginning of the IS220PTURH1B product number has dual functionality; defining this product both as a special-assembly version, and as a domestically-produced General Electric offering that was manufactured in their Salem, Virginia factory location.
