1.1.1.1 COMMUNICATION BOARDS WITHDRAWAL / INSERTION
The modular design of the relay allows for the withdrawal and insertion of the communication module.
Figure 1–2: shows the location of communication modules on the rear part of the relay. Qualified personnel must carry out
the insertion or extraction of the communication boards only after interrupting the relay auxiliary voltage and ensuring that
all the rear terminals are potential free.
Communication boards are installed on the rear of the unit, the upper port being reserved for the asynchronous
communications board and CAN, and the lower port for the ETHERNET board in any of its configurations.
Figure 1–2: MODULE WITHDRAWAL/INSERTION
WARNING: MODULE WITHDRAWAL AND INSERTION SHALL ONLY BE PERFORMED BY DULY QUALIFIED
SERVICE PERSONNEL. FOR PERSONAL SECURITY PURPOSES, BEFORE ACCOMPLISHING ANY
WITHDRAWAL OR INSERTION OPERATION, THE RELAY MUST BE POWERED OFF AND ALL THE REAR
TERMINALS MUST BE POTENTIAL FREE. THE RELAY MUST BE GROUNDED USING THE REAR GROUNDING
SCREW.
Before performing any of these actions, control power must be removed from the relay and all the rear terminals
must be potential free. A grounded antistatic wristband must be used when manipulating the module in order to avoid
electrostatic discharges that may cause damage to the electronic components.
WITHDRAWAL: Loosen the small screws that keep the faceplate in place and extract the module.
INSERTION: Insert the module and press it firmly in the case, until it is completely fixed. After this, bolt the faceplate
screws and replace the control power. Check that the relay is fully operative.
GE Multilin will not be responsible for any damage of the relay, connected equipment or personnel whenever
these safety rules are not followed.

1.1.1.2 MAGNETIC MODULE TERMINALS
The transformer module for the VTs and CTs is already connected to a female connector screwed to the case. The
current inputs incorporate shorting bars, so that the module can be extracted without the need to short-circuit the
currents externally. It is very important, for safety reasons not to change or switch the terminals for CTs and VTs.

1.1.3 SAFETY INSTRUCTIONS
The G650 ground screw shown in Figure 1–5: must be correctly grounded.
Figure 1–5: LOCATION OF GROUNDING SCREW
Before communicating with a G650 unit through the front serial port, please ensure that the computer is grounded.
In case of using a laptop, it is recommended not to have it connected to its power supply. In many cases it might not be
correctly grounded either due to the power supply or to the connector cables used.
This is required not only for personal protection, but also to avoid a potential voltage difference between the
relay’s serial port and the computer’s port, which could produce permanent damage to the computer or the relay.
GE Multilin will not be responsible for any damage to the relay or connected equipment whenever this elemental
safety rule is not followed.

1.2OVERVIEW 1.2.1 INTRODUCTION TO 650 FAMILY OF RELAYS
Historically, substation protection, control and metering functions were performed with electromechanical equipment. This
first generation of equipment was gradually replaced by analog electronic equipment (called static devices), most of which
emulated the single-function approach of their electromechanical precursors. Both of these technologies required
expensive cabling and auxiliary equipment to produce functioning systems.
Recently, digital electronic equipment has begun to provide protection, control and metering functions. Initially, this
equipment was either single function or had very limited multi-function capability, and did not significantly reduce the
cabling and auxiliary equipment required. However, recent digital relays have become quite multi-functional, reducing
cabling and auxiliaries significantly. These devices also transfer data to central control facilities and Human Machine
Interfaces using electronic communications. The functions performed by these products have become so broad that many
users prefer the term IED (Intelligent Electronic Device).
It is obvious to station designers that the amount of cabling and auxiliary equipment installed in stations can be even further
reduced, to 20% to 70% of the levels common in 1990, to achieve large cost reductions. This requires placing even more
functions within the IEDs.
Users of power equipment are also interested in reducing cost by improving power quality and personnel productivity, and
as always, in increasing system reliability and efficiency. These objectives are realized through software which is used to
perform functions at both the station and supervisory levels. The use of these systems is growing rapidly.
High speed communications are required to meet the data transfer rates required by modern automatic control and
monitoring systems. In the near future, very high speed communications will be required to perform protection signalling.
IEDs with capabilities outlined above will also provided significantly more power system data than is presently available,
enhance operations and maintenance, and permit the use of adaptive system configuration for protection and control
systems. This new generation of equipment must also be easily incorporated into automation systems, at both the station
and enterprise levels.
1.2.2 HARDWARE ARCHITECTURE
650 family of relays has been designed to meet the goals described above that are appearing nowadays in the environment
of new substations.
The 650 is a digital-based device containing a central processing unit (CPU) that handles multiple types of input and output
signals. The 650 family can communicate over a local area network (LAN) with an operator interface, a programming
device, or another 650 or UR device.
The CPU module contains firmware that provides protection elements in the form of logic algorithms, as well as
programming logic gates, timers, and latches for control features. It incorporates two internal processors, one for generic
use and a second one dedicated for communications.
Input Elements accept a variety of analog or digital signals from the field. The 650 isolates and converts these signals into
logic signals used by the relay.
Output Elements convert and isolate the logic signals generated by the relay into digital signals that can be used to control
field devices.

1.2.3 SOFTWARE ARCHITECTURE
The firmware (software embedded in the relay) has been designed using object oriented programming techniques (OOP).
These techniques are based on the use of objects and classes, and provide the software architecture with the same
characteristics as the hardware architecture, i.e., modularity, scalability and flexibility.
1.2.4 COMMUNICATIONS ARCHITECTURE
The main processor performs protection, control, and communication functions, incorporating two internal processors, one
for generic use and a second one dedicated for communications.
A dedicated serial port is used for communication between the main processor and the human-machine interface. The
serial connection provides great immunity against electromagnetic disturbances, thus increasing system safety.
All G650 units incorporate an RS232 serial port on the front of the relay. There is also a possibility to incorporate up to two
additional communication modules on the rear.
One of the modules provides asynchronous serial communications, using different physical media (RS485, plastic or glass
fiber optic) depending on the selected model. The module incorporates two identical ports, COM1 and COM2. The COM2
port is multiplexed with the front port. Additionally, this module may incorporate a port for CAN BUS communications, used
for the connection to the Remote CAN BUS I/O module. This feature allows increasing up to 100% the I/O capability, when
the maximum number of I/Os available inside the relay is not enough for a specific application.
Available options are:
Table 1–1: REAR SERIAL COMMUNICATIONS BOARD 1
The other module provides Ethernet communications (COM3 port), using 10/100BaseTX (self-negotiable speed) or
100BaseFX connectors, depending on the selected model. The most complete models include a double redundant
100BaseFX fiber optic port. Redundancy is provided at the physical level; the unit incorporates internally duplicated and
independent controllers for extended system reliability and accessibility.
Available Options are:
Table 1–2: REAR ETHERNET COMMUNICATIONS BOARD 2
For options C and D it is required to select the active physical media, by means of an internal selector inside the module.
The factory configuration for this selection is the 10/100BaseTX port.
Finally, internal communication with input and output modules is performed via an internal CAN bus, independent from the
one used for remote CAN BUS I/Os. This fact provides increased communication speed, as well as the possibility of
acknowledgement of modules, abnormalities, etc. As this is a serial port supporting a communications protocol, it provides
extraordinary immunity against external or internal disturbances.
