Our Reflective Memory technology is centered 

on an innovative and efficiently designed hardware platform that is easy to use, 

provides for greater distance between nodes, high noise immunity,

optional node bypass, and no software overhead. 

Just read and write to the onboard memory and the Reflective Memory node controller does the rest.

The PMC-5565PIORC is a Reflective Memory node card in PMC format.

Reflective Memory node cards are available in multiple form factors, including PMC, PCI Express,

PCI, low profile PCI Express, and VME. The family allows computers, workstations,

 PLCs, and other embedded controllers to all share data in real-time.

The transfer of data between nodes is software transparent so no processor overhead is required.

Data written into the Reflective Memory is broadcast to all nodes on the network without further involvement of the sending or receiving nodes. 

Benefits

• Highly scalable technology supports up to 256 nodes

• Bus independent design protects investments in your current network infrastructure

• Low latency, deterministic data transfer rate allows for predictable, high-perfor mance application deployment 

• Seamless integration with GE Intelligent Platforms’ SBC solutions and most industry standard offerings 

• Improved PIO read performance and field upgradeable firmware

Reflective Memory is an optical ring-based, ultra high-speed shared memory network solution.

It allows a distributed network to share real-time data at a deterministic rate,

regardless of bus structures and operating systems.

With more than 15 years of experience in this field, GE Intelligent Platforms

is an original pioneer of this technology and our 5565 Reflective Memory family extends our market leadership position. 

How do we do it? We keep it simple. 

The transfer of data between nodes is software transparent so no processor overhead is required.

Data written into the Reflective Memory is broadcast to all nodes on the network without further involvement of the sending or receiving nodes. 

Benefits

 Cost effective 35A brushless dual redundant regulator

configuration

 Improved reliability and less spare parts inventory

 Less maintenance and on-going training costs with

common software tools

 Better life-cycle support with more compute power for

upgrades and simplified controller replacement

 Risk mitigation of new technology with proven algorithms

and power bridges

Proven Technology

While controllers, networks, I/O modules, and software tools

are upgraded, the heart of the system remains the same.

Proven control and protection algorithms remain unchanged.

Similarly, mission-critical power bridge technology is carried

over from the EX2100 power conversion assemblies.

In addition, control cabinet footprints are unchanged and

compliance to international regulations and standards is retained.

The EX2100e uses the ToolboxST* application for

configuration and diagnostics and retains all attributes for

high-speed analysis of rotating machinery and the enhanced

look-and-feel of plant-level Distributed Control System

software. For example, the ToolboxST application can analyze

and configure I/O modules, controllers, networks, and

operator stations for generator controls, turbine controls, and

balance-of-plant controls to simplify maintenance.

Controllers

The Hydran 201Ti can be connected to optional controllers to facilitate

communication with multiple units and create a local network.

• The Ci-1 controller is a one channel controller that replicates some of

the human interface functions (gas value display, alarm buttons). This is

ideal when the 201Ti is mounted out of reach on an upper valve of the

transformer. It also brings down the alarm relay contacts and the analogue

output for easier wiring.

• The Ci-C controller receives the gas ppm data from up to four 201Ti,

providing a single communication point for all four monitors. It has no

alarm relay or analogue output. This is ideal when protecting 3 single phase

transformers + 1 spare.

It is possible to “daisy-chain” up to 32 controllers or 201Ti through their RS-485

port. The maximum chain distance (all cables added up) is 1200m (4000ft). All

the 201Ti connected to any of the daisy-chained controllers can be accessed

through any controller in the local network, thus facilitating communication by

only having to fit one RS-232 modem for example.

Human Interface

• Backlit LCD display of gas information

• Keypad to stop unit and acknowledge alarms

• Compatibility with GE’s acclaimed Perception™

software to download, trend and analyze

transformer data

Mark IV Improvements

• Completely overhauled with improved sensor

durability, new electronic boards and power

supply to make it RoHS compliant while

increasing device reliability and capabilities

• Local USB port to replace the RS-232 port no

longer found on most field laptops

• Digital output of registers using Modbus®

protocol communication over isolated RS-485

Easy Asset Supervision

• Permanently mounts on a single transformer oil

valve. No extra piping or pump required

• “Composite gas” sensor responds 100% to

Hydrogen (general fault gas) and is also sensitive

to Carbon Monoxide (overheated paper)

Acetylene (arcing) and Ethylene (overheated oil)

thus covering main failure root causes

• “Hydrogen only” gas sensor is simpler and

responds 100% to Hydrogen gas only, the

general fault gas

Configurable Alarms

• An alarm is raised when an abnormal level of

fault gas is detected

• Two alarm levels (one for Alert and one for Alarm)

can be set to show increasing severity

• Alarms can be set on gas ppm levels or on gas

rate of change (ROC) over an hour or a day

• Automatic self-test every 15 days will trigger

service alarm if it detects a fault, including power

failure, oil valve closed, sensor or  battery needing

replacement

Key Benefits

• Continually measures key fault gas to give you an insight into the transformer’s condition

• Choice of gas sensor: traditional “Composite gas” or more basic “Hydrogen only”

• Communicates gas ppm and gas rate of change values remotely to avoid site visits and enable

remote supervision

• Fourth generation of this continuously improved design, with over 25.000 units sold worldwide

Applications

Power Utilities

• Simple and effective solution for less-critical transformers

• Focuses and prioritizes asset replacement strategy

Industrial Plants

• Reduces the risk of process interruption due to power failure

• Minimizes costly production downtime

Essential DGA monitoring for transformers

Transformers are key and expensive components of the electrical grid and knowledge of their

health condition is essential to having a reliable network. When a transformer’s insulation system is

overstressed, gases are produced that dissolve in the oil. Dissolved Gas-in-oil Analysis (DGA) is recognized

as the best indicator of developing faults.

The Hydran™ 201Ti is a small and easy to setup continuous Dissolved Gas-in-oil Analysis (DGA) monitor.

It provides the basic information used by IEEE® Standard C57.104 and can be used as an essential first

line of defence for the transformers in your fleet to obtain advance warning of a failure condition and

minimize the risk of an unplanned outage.

The 201Ti uses fuel cell technology (described as fixed instruments – method 3 in the standard) and is

now available with a choice of either the world renown “Hydran Composite Gas” sensor which responds

100% to Hydrogen and is also sensitive to Carbon Monoxide, Acetylene and Ethylene or the more basic

“Hydrogen Only” sensor which focuses purely on Hydrogen gas generation.

Because the monitoring unit mounts on a single valve and uses Dynamic Oil Sampling, there is no need

for a pump or extra piping to connect to different valves. Due to its uncomplicated features and the easily

understood information it provides, the 201Ti has been amongst the monitors of choice for many years,

with one of the largest installed base of any DGA monitor.
