GE IS230TNTRH1C | Turbine Network Terminal Board
The GE IS230TNTRH1C is a Turbine Network Terminal Board (TNTR) that acts as an interface for the Mark VIe I/O packs. It is often paired with the TTUR board to handle specific pulse and digital signal distribution across the IONet (the Mark VIe internal Ethernet-based communication network).
Product Parameters (Datasheet)
- Model Number: IS230TNTRH1C
- Board Type: Turbine Network Termination (TNTR)
- Network Interface: IONet (High-speed 100 Mbps Ethernet)
- Mounting: Typically DIN-rail or rack-mounted via a plastic carrier
- Compatibility: Compatible with VTUR and PTUR I/O packs
- I/O Support: Specialized for speed monitoring and high-speed pulse processing
Product Technical Description
These two boards often work in tandem within the Mark VIe architecture. The TTURH1C provides the rugged terminal points for high-voltage and high-frequency field wiring (like magnetic speed pickups), while the TNTRH1C facilitates the connection of the digital I/O packs that process these signals. The “IS230” designation for the TNTR indicates it is a more modern, compact hardware assembly compared to legacy IS200 series boards, optimized for the high-speed IONet environment.
Product Usage Instructions
- Installation: Mount the boards on a standard 35mm DIN rail using the provided carrier. Ensure the TTUR is positioned to minimize the length of sensitive speed sensor cables.
- I/O Pack Seating: Carefully plug the appropriate I/O packs (e.g., VTUR) directly onto the terminal board connectors. Ensure the pins are aligned to avoid bending.
- Wiring: Use shielded twisted-pair cables for all speed sensor (magnetic pickup) inputs to prevent electromagnetic interference (EMI) from inducing false speed signals.
- Grounding: Ensure the shield drain wires are connected to the designated ground bar on the terminal board to ensure signal integrity.
- Configuration: Use GE ControlST software to configure the scaling factors for the pulse rate inputs and the threshold levels for overspeed protection.
Q&A (Common Questions)
Q: Can I use the TTURH1CFD in a TMR system? A: Yes, the “H1C” revision is designed to support Simplex, Dual, and Triple Modular Redundant (TMR) configurations by branching the signals to three separate I/O packs.
Q: What is the significance of the “FD” suffix on the IS200 board? A: This suffix refers to specific manufacturing revisions, often involving conformal coating for protection against moisture and contaminants or updated component selections.
Q: Does the IS230TNTRH1C require its own power supply? A: No, it typically draws power from the 24V DC IONet connection provided by the I/O pack or the system power distribution module.
