Component Details

IS220PTURH1B – PTUR Pack

The IS220PTURH1B serves as the electrical interface between one or two I/O Ethernet networks and a turbine control terminal board. Each pack includes:

• A processor board (common to all Mark VIe distributed I/O packs)

• A function-specific control board for turbine protection

• An analog acquisition daughterboard

The pack connects to the TTURH1C terminal board and manages the following:

• Four speed sensor inputs

• Bus and generator voltage inputs

• Shaft voltage and current signals

• Eight flame sensor inputs

• Outputs to the main breaker

Inputs/Outputs:

• Input: Dual RJ45 Ethernet connectors and a 3-pin power input

• Output: DC-62 pin connector that mates directly with the terminal board

Diagnostics:

• Visual indicators via status LEDs

• Local diagnostics via an infrared communication port

Mounting and Configuration

• The PTUR pack mounts directly to the Mark VIe TTURH1C terminal board

• The terminal board supports Triple Modular Redundancy (TMR) with three DC-62 pin connectors for I/O packs

• It can also operate in simplex mode with a single PTUR pack installed

System Integration: Mark VIe Control System

The Mark VIe system is a flexible and scalable control platform used in a variety of large industrial applications. Key features include:

• High-speed, networked I/O for Simplex, Dual, and TMR systems

• Industry-standard Ethernet communications for I/O, controllers, operator interfaces, and third-party system integration

• Compatible with ControlST™ software suite, including ToolboxST™, for configuration, diagnostics, and trending

The Mark VIeS Safety controller and I/O components support IEC 61508 safety-critical applications and can operate either independently or integrated with standard Mark VIe controllers. ToolboxST™ allows secure configuration and programming of Safety Instrumented Functions (SIFs), with certified hardware/software blocks ensuring system integrity.
