Product Overview

The IS200TVIBH2BCC is a dedicated vibration termination interface board built for the GE Mark VI Speedtronic turbine control platform. It routes raw analog signals from proximity probes, accelerometers and velocity transducers to paired VVIB processing boards, while supplying regulated‑24 VDC power to field‑mounted machinery sensors. Conformal PCB coating protects circuit traces against cabinet humidity and airborne contaminants typical within power‑generation environments.

This hardware solves critical field challenges for turbine safety monitoring: reliable multi‑channel vibration signal buffering, convenient on‑board BNC test points for handheld diagnostic tools, and native compatibility with both simplex and TMR redundant system architectures. It eliminates custom wiring work between vibration probes and control processing hardware, preserving signal integrity over long field cable runs. Turbine maintenance engineers, power‑plant retrofit teams and system integrators benefit most; this spare board restores shaft‑vibration, axial‑position and eccentricity monitoring functions without altering existing Mark VI system configuration. It installs directly into standard Mark VI card slots and supports up to 14 connected vibration sensor channels for rotating‑asset protection workflows.

Key Application Notes

• Must pair with Mark VI VVIB vibration processing boards for signal digitization; does not perform standalone data conversion
• BNC test ports allow technicians to capture live sensor signals without disconnecting field wiring
• Supports TMR triple‑modular‑redundant configurations where one termination board interfaces to three separate VVIB units
• Intended strictly for cabinet‑mount use; not for direct field‑deployment outdoors or in wet locations
