1.2OVERVIEW 1.2.1 INTRODUCTION TO 650 FAMILY OF RELAYS
The GE 650 family relay is a new generation of digital and multifunction equipment that is easily incorporated into
automation systems, at both the station and enterprise levels.
1.2.2 HARDWARE ARCHITECTURE
a) F650 BASIC DESIGN
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 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.
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.
