Installation Guide

• Mount the I/O pack with the correct terminal board (IS200TRPAH1A for Mark VIe).
• Connect power supply at 28V DC (27.4 to 28.6 range).
• Wire voltage detection inputs (16 to 140V DC).
• Connect E-stop input (18 to 140V DC).
• Wire speed inputs (-15 to +15V DC).
• Connect contact outputs (24 to 28V DC, max 7A).
• Follow hazardous location guidelines if used in classified areas.
• Use only approved hardware combinations for safety.

Compatibility Notes

• Works with Mark VI and Mark VIe turbine control systems.
• Requires terminal board IS200TRPAH1A for Mark VIe.
• Also works with IS220PTURH1A (older version).
• For Mark VIeS, use YTUR series modules.
• Used in combined cycle power plants with DCS systems.

Typical Applications

• Gas turbine primary protection
• Steam turbine primary protection
• HRSG (boiler) control
• Auxiliary plant controls
• Motor-operated valve control
• Combined cycle power plants
• Boiler drum level control

Diagnostic Capabilities

• Monitors voltage detection inputs for abnormalities
• Checks E-stop circuit status continuously
• Verifies speed input signals from turbine
• Reports trip conditions to Mark VI controller
• Provides status through system HMI

Maintenance Tips

• Check power supply voltage regularly. Keep within 27.4 to 28.6V DC.

Professional FAQ

• What is the difference between IS220PTURH1A and IS220PTURH1B?
• The B version is a later sub-revision. Both work with the same terminal board. Check your system requirements before choosing.
• Can I use this module with Mark VIeS systems?
• No. Mark VIeS uses YTUR series modules (IS220YTURS1A or IS220YTURS1B). PTUR modules are for Mark VIe standard systems.
• Experience: My E-stop input is not responding. What should I check?
• Measure voltage at the input. It must be between 18 and 140V DC. Also check wiring to the TRPA terminal board.
• Experience: The module gets warm during operation. Is this normal?
• Yes. The module draws 0.41A at 28V. Ensure proper airflow around the I/O pack. Do not block ventilation.
• Buying guide: Do I need the terminal board IS200TRPAH1A?
• Yes. The I/O pack alone does not have connectors. You need the terminal board for wiring field devices. Order both together.
• Buying guide: Can I replace PTURH1A with PTURH1B?
• Yes. PTURH1B is backwards compatible. Test the system after replacement to confirm normal operation.
• Buying guide: What power supply do I need?
• You need a 28V DC supply with at least 0.5A capacity. Voltage must stay between 27.4 and 28.6V for proper operation.
• Is this module approved for hazardous locations?
• Yes. When used with terminal board IS200TRPAH1A, the combination is approved for hazardous locations. Follow installation rules.
