FUNCTIONAL DESCRIPTION:

IS200BPDIH1A is a Discrete Input Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. A Discrete Input Module is designed to receive and process on/off signals (digital signals) from field devices such as switches, sensors, and other binary sources. In turbine control systems, these signals often represent statuses like trip signals, limit switches, or safety interlocks. The module converts the incoming discrete signals into a form that the turbine controller can use for monitoring, control logic, and safety functions.

• Receives digital on/off signals from field devices such as switches, sensors, and relays.
• Converts and conditions discrete signals for interpretation by the turbine controller.
• Continuously monitors input signals for real-time status updates.
• Supports safety and control logic execution, including trip signals and interlocks.
• Provides electrical isolation to protect the turbine control system from faults and transients.

OPERATION:

The module continuously scans input channels from connected field devices to detect active or inactive states. Incoming signals are filtered, isolated, and converted into logic-level signals for the turbine controller. The processed signals are transmitted via the controller’s communication bus, enabling real-time monitoring, alarm generation, safety trips, and execution of control logic. The module also provides diagnostic feedback to detect wiring faults, device failures, or abnormal conditions, supporting safe and uninterrupted turbine operation. These processed signals are transmitted through the system’s serial communication bus, allowing the turbine controller to perform real-time monitoring, execute safety trips, trigger alarms, and implement control logic sequences. In addition, the module provides continuous diagnostic feedback, enabling the system to detect wiring issues, device malfunctions, or abnormal operating conditions before they affect turbine performance.

COMPATIBILITY:

It integrates seamlessly with other modules in the Mark VI/VIe rack, including output modules, analog input/output modules, processor boards, and communication interfaces, allowing for coordinated turbine control and protection. The module supports standard discrete input signal types used in turbine operations, such as trip signals, limit switches, and interlocks, ensuring accurate and reliable acquisition of field device data. Its design also accommodates both new installations and retrofit applications, making it suitable for upgrading existing turbine control systems without requiring major changes to the control architecture.

FREQUENTLY ASKED QUESTIONS:

What is the nominal input voltage and current for each channel?

Each discrete input channel is designed for DC signals in the range of 18–32 V, with a nominal operating voltage typically 24 V DC. Input current per channel is low, usually in the range of 3–5 mA, sufficient to detect logic transitions without loading field devices.

What is the input current requirement per channel?

Input current is typically 3–5 mA per channel, ensuring minimal load on field devices while maintaining reliable detection of on/off states.

What is the timing specification for input detection?

The input scan rate is typically 2–5 milliseconds per channel, and the module provides synchronous updates to the controller, ensuring minimal latency for safety-critical signals.

How should I handle boards in terms of static sensitivity?

Treat all boards as sensitive to static electricity. Utilize a grounding strap when changing boards to dissipate static charge. Additionally, store boards in anti-static bags or the original shipping boxes to minimize static-related risks.
