Description

GE IS230TNCIH4C Mark VIe Terminal Board for Discrete I/O

Product Overview

The GE IS230TNCIH4C is a high-reliability discrete I/O terminal board designed for GE’s Mark VIe Speedtronic™ turbine control system, a cornerstone of power generation, oil and gas, and industrial automation. As a critical interface component, this board facilitates connections between field devices (such as limit switches, relays, and solenoids) and Mark VIe I/O modules, enabling seamless signal transmission in safety-critical turbine control systems. The IS230TNCIH4C supports 16 discrete input channels and 16 discrete output channels, with built-in isolation to prevent ground loops and electromagnetic interference—key for maintaining signal integrity in harsh industrial environments.

 

Engineered for ruggedness, the IS230TNCIH4C operates reliably across -40°C to +70°C and features a durable metal enclosure, making it suitable for offshore platforms, power plants, and refineries. Its DIN rail mounting simplifies installation in compact control cabinets, while compatibility with Mark VIe I/O modules like IS230SNRTH2A and IS220PDOAH1B ensures seamless integration into existing systems. The board’s LED status indicators provide instant visual feedback on channel activity and fault conditions, enhancing diagnostic efficiency.

 

Within the Mark VIe ecosystem, the IS230TNCIH4C acts as a bridge between field sensors/actuators and the main control processor, translating raw discrete signals into actionable data for turbine protection and process optimization. Compliance with UL 508 and IEC 61010 standards underscores its reliability in regulated industrial settings, where safety and uptime are paramount.

Main Features and Advantages

High-Density Discrete I/O: The IS230TNCIH4C offers 16 inputs and 16 outputs in a compact form, reducing the number of boards needed in control cabinets. This density optimizes space utilization, critical for crowded power plant or offshore platform enclosures. Each channel is isolated to prevent signal interference, ensuring reliable communication between field devices and Mark VIe modules.

 

Industrial-Grade Durability: With a -40°C to +70°C operating range and robust metal enclosure, the IS230TNCIH4C withstands extreme temperatures, vibration, and corrosive atmospheres—common in refineries and chemical plants. Its design resists dust and moisture, maintaining performance in environments where traditional terminal blocks might fail.

 

Seamless Mark VIe Integration: The board is specifically engineered to pair with Mark VIe I/O modules like IS220PDIAH1BE (discrete input) and IS220PDOAH1B (discrete output), creating a cohesive discrete control system. This compatibility simplifies retrofits, as existing Mark VIe users can integrate the IS230TNCIH4C without extensive reconfiguration.

 

Real-Time Diagnostics: Integrated LED indicators display power status, channel activity, and fault conditions (e.g., short circuits), enabling technicians to quickly identify issues during maintenance. This reduces troubleshooting time, minimizing downtime in 24/7 operations like turbine control.

 

Flexible Wiring Options: The IS230TNCIH4C features screw terminals for secure wire connections, accommodating 14–22 AWG cables. This flexibility supports diverse field devices, from small limit switches to heavy-duty solenoids, enhancing its versatility across industries.

Application Fields

The GE IS230TNCIH4C is indispensable in industries relying on precise discrete control for turbine and industrial systems:

 

  • Power Generation: In thermal, combined-cycle, and nuclear plants, it connects turbine trip switches, valve position sensors, and auxiliary motor relays to Mark VIe controllers. Its isolation prevents signal interference, ensuring accurate monitoring of safety interlocks—critical for preventing unplanned shutdowns.
  • Oil and Gas: Offshore platforms and refineries use the IS230TNCIH4C to link emergency shutdown (ESD) buttons, pump status sensors, and compressor anti-surge valves to control systems. Its rugged design withstands salt spray and vibration, maintaining reliability in harsh offshore conditions.
  • Industrial Manufacturing: Chemical plants and paper mills deploy the board to manage conveyor belt sensors, mixer start/stop relays, and process alarms. Its high channel count simplifies wiring for complex production lines, reducing installation costs.
  • Marine Propulsion: Shipboard turbine systems use the IS230TNCIH4C to connect engine safety sensors (e.g., overheat alarms) and throttle control solenoids. Its compact size fits in limited shipboard space, while its durability resists the effects of constant motion.

Installation and Maintenance

Pre-installation preparations: Ensure the DIN rail is securely mounted and grounded, with adequate space for wiring. Verify the 24V DC power supply meets voltage tolerances (±10%). Align the IS230TNCIH4C with the rail, secure it with clips, and confirm terminal labels match the wiring diagram. Before connecting field devices, test continuity of input/output channels using a multimeter to avoid short circuits.

 

Maintenance suggestions: Conduct monthly visual inspections to check for loose terminals, damaged wires, or dim LEDs—indicators of potential issues. Clean dust from the board using compressed air to prevent overheating. Quarterly, verify isolation between channels with a megohmmeter to ensure no degradation. When replacing the IS230TNCIH4C, label wires before removal to simplify reinstallation, and retest all channels post-installation to confirm proper operation.
