1.Specification:
2. Functional Description
IS210DTCIH1A is an unmanaged industrial IONet Ethernet switch module designed and developed by GE. It is a core communication component of GE Mark VIe and Mark VIeS safety distributed turbine control systems, dedicated to real-time data exchange between system controllers, I/O packs, and upper monitoring devices.
The ESWB series switches are purpose-built for Mark VIe IONet private industrial Ethernet networks, which exclusively serve GE turbine control I/O modules and safety controllers. This module delivers high-speed 10/100 Mbps full-duplex data forwarding, establishes stable communication links across gas, steam and wind turbine control cabinets, and supports both simplex and redundant network architectures for safety instrumented system (SIS) applications.
3. Module Key Features
- Equipped with eight auto-sensing 10/100 BASE-TX RJ45 copper ports, auto-negotiates transmission speed and duplex mode automatically to simplify field wiring configuration.
- Dual redundant wide-range DC power inputs (18–36 VDC) eliminate single-point power failure risk, maintaining continuous network operation during power source switching.
- Wide industrial operating temperature range of -40°F to 158°F, stable performance under high humidity (0%–95% non-condensing) factory environments.
- Compliant with Class 1 Div 2 and ATEX Zone 2 hazardous location certifications, suitable for gas turbine power plant hazardous area installation.
- Supports standard industrial communication protocols including TCP/IP, UDP, FTP, HTTP, Modbus/TCP for seamless interconnection with control and monitoring equipment.
- Dual installation options: vertical/parallel DIN rail mounting with dedicated fixtures, or rear panel wall mounting via integrated screw brackets; seismic vibration-resistant design for cabinet stability.
- Built-in LED status indicator lights for each port and power supply, providing real-time visual diagnostics for link status, data activity and power health to accelerate troubleshooting.
- Unmanaged plug-and-play design, no software configuration required after wiring; optimized low-latency forwarding to meet real-time control loop timing demands.
- Compact lightweight form factor saves cabinet space, with rugged metal housing for electromagnetic interference suppression.
4. UCSB Installation Guide
- Select the mounting method: install dedicated DIN rail fixtures for rail mounting, or fasten the module directly to cabinet panel via rear mounting holes. Ensure vertical airflow around the module is unobstructed.
- Secure the IS210DTCIH1A firmly to the mounting surface to withstand industrial vibration and shock loads.
- Connect primary and backup DC power sources to the two redundant power terminals; nominal 24/28 VDC supply is recommended for Mark VIeS system matching.
- Wire Ethernet cables to the RJ45 ports: connect controllers, YAIC analog I/O packs, UCSB safety controllers and HMI monitoring devices as per system network topology requirements.
- Verify port LED indicators to confirm valid link establishment and normal data transmission activity.
- No additional software setup is required; the unmanaged switch operates immediately after power is applied for IONet network communication.
Connectors
The following connectors are integrated on the IONet switch module:
- Eight RJ45 10/100 BASE-TX copper Ethernet ports for IONet device interconnection
- Dual terminal block power connectors for redundant 18–36 VDC power supply input
- Multi-position mounting screw holes and DIN rail latch fixtures for mechanical installation
5. Networking Capabilities
- Dedicated IONet private industrial Ethernet interface exclusive to Mark turbine control systems, isolating safety control traffic from plant office IT networks.
- 8-port copper RJ45 expansion enables flexible daisy-chain or star topology cabinet network layout design.
- Auto MDI/MDI-X crossover function eliminates the need for special cross-over Ethernet cables during field installation.
Full-duplex transmission eliminates data collision and maximizes real-time control signal throughput for turbine safety loops.
Redundancy Considerations
- Dual redundant power inputs provide power source failover without manual intervention.
- Dual IONet network topologies can be implemented by deploying two IS210DTCIH1A switches per control cabinet to create fully redundant communication paths for TMR safety controllers and I/O packs.
- The switch itself does not support internal port redundancy; system-level redundancy is achieved via separate parallel switch hardware deployment.
Diagnostics and Environmental Performance
- Per-port LED link/activity indicators plus dual power status LEDs for continuous visual operational diagnostics.
- Full power-up self-test on startup to validate internal switching hardware, power regulation circuits and port transceiver functionality.
- Operating ambient temperature range of -40 to 158 °F, engineered for outdoor power plant and heated turbine cabinet harsh environments.
- Rugged metal enclosure with IP30 ingress protection against dust and incidental contact.
