FUNCTIONAL DESCRIPTION:

IS230TNVBH8A is a Simplex Vibration Input Assembly DIN Rail Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Speedtronic Distributed Control Systems. A single-board controller is the heart of the system. The controller includes the main processor and redundant Ethernet drivers to communicate with networked I/O, and additional Ethernet drivers for the control network. A real-time, multi-tasking operating system is used for the main processor and I/O modules. Control software is provided in a configurable control block language and stored in non-volatile memory. It is similar to IEEE� 854 32-bit floating-point format, and Sequential Function Charts (SFC) are also available for complex sequencing. The I/O network (IONet) is a dedicated, full-duplex, point-to-point protocol. It provides a deterministic, high-speed 100 MB communications network that is suitable for local or distributed I/O devices, and provides communication between the main controllers(s) and networked I/O modules. Online controllers continuously read input data directly from the IONet, which is available in single, dual, and triple redundant configurations. Both copper and fiber interfaces are supported.

RACK CHASIS:

The rack chassis is available in 16-slot, 8-slot, and 4-slot sizes. 16-slot and 8-slot racks are available with an optional lockable faceplate and integral touchscreen display, while 4-slot racks are intended for blind (no display) or remote display applications only. Slot 1 in all racks is reserved for the Rack Connection Module (RCM). Slots 2 and 3 are available for System Access Modules (SAMs) or monitoring modules. Slots 4-16 are available for monitoring modules only. Racks may be mounted in a panel cutout, on 19” EIA rails (16-slot rack only), or with the back flush against a wall or surface (i.e., bulkhead mounting). The rack and its optional door/touchscreen can be mounted such that modules insert from the front (behind the door) or rear (side opposite the door). The rear-insertion option is particularly useful when retrofitting older monitoring systems where wiring lands on the back of the rack.

RACK CONNECTION MODULE:

This module accepts simplex or redundant +24Vdc power and distributes this power to all other installed modules via the rack backplane. It also accepts discrete inputs from external contact closures to invoke rack-wide functions, including Alarm Reset, Bypass, Trip Multiply, and Special Alarm Inhibit. The system’s Fault (NOT OK) Relay is contained in the RCM. One RCM must be installed in slot 1 of every rack. A variation on the RCM called the Power Connection Module (PCM) is an optional accessory that may reside in any rack slot. It is used in conjunction with the RCM for redundant power schemes. The PCM is identical to the RCM, but has connections only for Power 1 (P1) and Power 2 (P2). The presence of both an RCM and a PCM in a rack allows either of these modules to be removed without interrupting rack power, providing the highest level of tolerance to single-point failures.

PROGRAMMABLE 4-20 MA OUTPUTS:

Each monitor module provides the same number of 4-20 mA outputs as channels. However, these outputs can be assigned to any channel in the module and any measurement. For example, a 4- channel monitor can assign its direct measurement from each channel to a corresponding 4-20 mA output. Or, it can assign a channel’s direct measurement to analog output 1, its 1X amplitude to analog output 2, its 1X phase to analog output 3, and its gap voltage to analog output 4. There are no restrictions as to measurement type or channel, provided the value originates on the same module as the 4-20mA output.

PEER-TO-PEER I/O LEVEL COMMUNICATIONS:

Local processors in I/O modules can communicate data peer-to-peer with local processors in other I/O modules without the latency of communicating with the main controller. As an example, Power Load Unbalance is used on large steam turbines to quickly close control valves and intercept valves during a load rejection that might lead to rapid acceleration. One I/O module compares the turbine mechanical power (analog inputs) with the generator load (current transformer inputs) and quickly commands the valves to close via a peer-to-peer transmission to the I/O module that controls the valves.

FREQUENTLY ASKED QUESTIONS:

What is the IS230TNVBH8A?

It is a Simplex Vibration Input Assembly DIN Rail Module manufactured by General Electric as part of the Mark VIe series. It is designed to interface vibration and position sensors with GE Speedtronic Distributed Control Systems. The module conditions input signals and communicates them to the I/O network for real-time monitoring, diagnostics, and turbine protection.

How does the module handle 4–20 mA outputs?

Each channel has a programmable 4–20 mA output, which can be assigned to any measurement from the module. Users can map direct channel measurements, 1X amplitude, phase, or gap voltage to any output without restrictions. This flexibility allows seamless integration with turbine monitoring systems or external control devices.

What sensors are compatible with the IS230TNVBH8A?

It supports proximity probes, accelerometers, eddy-current probes, velocity transducers, and keyphasor sensors. The module conditions these signals for reliable transmission to the control system, ensuring compatibility with standard turbine monitoring setups.

How does it integrate with Mark VIe I/O networks?

The IS230TNVBH8A communicates via the IONet deterministic 100 MB full-duplex network. It supports single, dual, and triple redundant configurations, providing real-time communication between the module, other I/O devices, and the main controller for fast and reliable data transfer.
