Description

GE IS230TNRLH1B Product Specification

Product Overview

The GE IS230TNRLH1B is a high-reliability relay output terminal board engineered for GE’s Mark VIe Speedtronic Turbine Control System, serving as a critical interface for switching and controlling industrial equipment in automation systems. Designed to manage high-current loads from relays, this module enables precise actuation of valves, motors, and safety interlocks in gas turbines, steam turbines, and rotating machinery across power generation, oil and gas, and heavy manufacturing.

As part of the Mark VIe distributed control architecture, the GE IS230TNRLH1B features 8 relay output channels rated for 250 VAC/10 A, with a nominal control voltage of 28 VDC. Its dual redundant 100 Mbps Ethernet ports ensure seamless communication with the Mark VIe controller, while the rugged construction—including a triple-layer conformal coating and IP20-rated enclosure—ensures reliable operation in harsh environments (-30°C to +65°C) with high vibration, humidity, and chemical exposure.

In automation systems, the GE IS230TNRLH1B acts as the switching backbone for critical control loops, translating digital commands from the controller into physical actuation of field devices. Its compatibility with IS220PDIOH1B I/O modules and IS200STCIS1A terminal boards allows deployment in hazardous locations (Class I, Division 2), adhering to safety standards for explosive atmospheres. The module’s compact 3U VME form factor and hot-swappable design simplify integration and maintenance, making the GE IS230TNRLH1B indispensable for maintaining uptime in mission-critical operations.

Main Features and Advantages

High-Current Relay Control:
The GE IS230TNRLH1B delivers 8 relay outputs rated for 250 VAC/10 A, enabling direct control of high-power devices like turbine fuel valves, compressor anti-surge valves, and emergency shutdown (ESD) actuators. This capability eliminates the need for intermediate relays, reducing system complexity and potential failure points.

Redundant communication:
Dual 100 Mbps Ethernet ports with IONET protocol support ensure uninterrupted data transmission to the Mark VIe controller. In redundant architectures, automatic failover (<10 ms) maintains control continuity, critical for safety-critical systems where even brief communication loss could cause operational disruptions.

Hazardous location readiness:
When paired with IS200STCIS1A terminal boards and explosion-proof enclosures, the GE IS230TNRLH1B meets Class I, Division 2 standards, making it suitable for oil refineries, chemical plants, and offshore platforms. Its 2500 Vrms isolation prevents sparking, mitigating ignition risks in explosive atmospheres.

Rugged industrial design:
A triple-layer conformal coating protects against salt spray, dust, and chemical vapors, while the module’s vibration resistance (10–2000 Hz, 10 G rms) ensures reliability in high-vibration environments like turbine halls. The wide operating temperature range (-30°C to +65°C) adapts to extreme climates, from arctic pipelines to desert power plants.

Hot-swappable operation:
The GE IS230TNRLH1B supports hot swapping, allowing replacement without powering down the control system. This feature cuts mean time to repair (MTTR) to under 15 minutes, critical for maintaining uptime in mission-critical applications.

Application Areas

Power Generation:
- Controls gas turbine fuel supply valves, regulating flow rates during startup, shutdown, and load changes to optimize combustion efficiency.
- Actuates steam turbine bypass valves, diverting excess steam to condensers during grid fluctuations to prevent overpressure.
- Triggers generator circuit breakers in protection systems, isolating faults to safeguard equipment and grid stability.
Oil and Gas:
- Manages pipeline block valves via relay outputs, enabling remote shutdowns during leaks or pressure anomalies.
- Controls compressor anti-surge valves in offshore platforms, maintaining stable flow to prevent mechanical damage.
- Activates fire suppression systems in refineries, responding to heat detector signals with rapid valve actuation.
Manufacturing:
- Operates robotic welding arm relays in automotive plants, synchronizing motion with assembly line conveyors.
- Controls oven heating elements in food processing facilities, regulating temperatures via relay switching to ensure product quality.
Renewable Energy:
- Actuates wind turbine brake systems during high winds, feathering blades to reduce rotational speed and prevent structural stress.
- Switches solar inverter connections to battery storage systems, optimizing energy distribution during peak demand.

Installation and Maintenance

Pre-installation preparations: Before installing GE IS230TNRLH1B, verify the control cabinet is grounded to prevent electrostatic discharge (ESD) and that ambient conditions (-30°C to +65°C, 5–95% humidity) match specifications. Use an ESD wrist strap during handling. Mount the module in a 3U VME rack with 50 mm clearance for airflow, securing it with anti-vibration brackets. Connect the IS200STCIS1A terminal board to relay outputs and Ethernet cables to the Mark VIe controller, ensuring proper polarity and torque on terminal screws (0.5–0.7 N·m).

Maintenance suggestions: Perform monthly visual inspections of GE IS230TNRLH1B front-panel LEDs (Power, Fault, Relay Status) to confirm normal operation. Clean dust from ventilation slots with compressed air to avoid overheating. Quarterly, test relay contacts with a multimeter to check for resistance (>100 mΩ indicates wear). Annually, update firmware via GE’s Proficy software to address compatibility issues. Replace relays every 5–7 years or if switching delays exceed 10 ms, as degraded contacts can cause operational lag in safety-critical systems.
