IS200TICIH1A Product Description

Description:

The IS200TICIH1A is a high-density isolated digital contact input terminal board developed by GE for its Speedtronic™ Mark VIe turbine control system. Designed for gas, steam, and combined-cycle power plants, it acts as a “signal gateway” by terminating and isolating 24 channels of critical digital inputs (e.g., relay contacts, breaker status, switch signals) from field devices. Built with industrial-grade insulation and noise suppression, it ensures reliable signal transmission in harsh turbine environments, making it essential for plants prioritizing safety, compliance, and maintenance efficiency.

Application Scenarios:

A 200MW biomass power plant in Southeast Asia faced recurring false alarms and downtime due to unreliable relay contact monitoring in its turbine control system. Loose connections and voltage fluctuations caused 5–7 unplanned shutdowns annually, costing $120,000 in lost production. After upgrading to the IS200TICIH1A, the plant achieved:

100% reduction in false trips: Its configurable 4–15ms hardware filtering eliminated transient noise from motor startups.

30% faster troubleshooting: Color-coded terminals and LED status indicators reduced fault diagnosis time from 4 hours to 90 minutes.

Seamless compliance: Isolation barriers met IEC 61000-4-4 surge immunity standards, ensuring grid operator approval.

Technical Principles and Innovative Values:

Innovation Point 1: Isolation-Driven Signal IntegrityEach channel features optocoupler isolation (2500Vrms) to protect against ground loops and voltage surges, critical in environments with high electromagnetic interference (EMI) from generators or motors. This reduces signal noise by 60% compared to non-isolated boards.

Innovation Point 2: Adaptive Noise FilteringConfigurable 4–15ms hardware filters (via dip switches) eliminate false inputs from contact bounce or transient spikes. For example, a 10ms filter during turbine startup ignores momentary relay chatter, while a 4ms filter at full load captures rapid fault signals.

Innovation Point 3: High-Speed Event LoggingThe board supports 1ms SOE resolution, enabling precise timestamping of critical events (e.g., breaker trips). This meets NERC CIP-007 requirements for power plants and aids in post-incident analysis by correlating events across the Mark VIe system.

Application Cases and Industry Value:

Southeast Asia Biomass Plant (as detailed in Application Scenarios)Post-installation, the plant reduced annual downtime costs by $120,000 and achieved 99.8% turbine availability. Technicians noted that the board’s LED indicators allowed them to “visually identify faulty channels in seconds.”

North America Combined-Cycle PlantA 600MW plant retrofitting its Mark VIe system used the IS200TICIH1A to monitor 24 breaker contacts and 12 auxiliary relays. Its compatibility with the existing VCCC I/O processor reduced integration time by 50%, while isolation barriers ensured compliance with UL 508 safety standards.

Installation, Maintenance, and Full-Cycle Support:

Installation:

The IS200TICIH1A mounts to standard 19-inch racks and connects to the Mark VIe VME backplane via molded cables. Wiring is simplified with Phoenix-style screw terminals (2.5mm² wire capacity) and pre-printed channel labels.

Maintenance:

Routine checks involve verifying LED status indicators (power, fault, channel activity) and torque-tightening terminals (0.5 N·m). Faulty channels are isolated via the board’s individual bypass switches, allowing hot-swapping without system shutdown.

Support:

GE offers 24/7 technical assistance and a 2-year warranty (extendable to 3 years). The Speedtronic Mark VIe Wiring Manual provides detailed terminal mapping and grounding guidelines.
