2 PRODUCT DESCRIPTION 2.1INTRODUCTION
The C30 Controller System is a microprocessor-based device designed for power substation control and monitoring.
Diagnostic features include a sequence of records capable of storing 1024 time-tagged events. The internal clock used for
time-tagging can be synchronized with an IRIG-B signal or via the SNTP protocol over the Ethernet port. This precise time
stamping allows the sequence of events to be determined throughout the system. Events can also be programmed (via
FlexLogic™ equations) to trigger oscillography data capture which may be set to record the measured parameters before
and after the event for viewing on a personal computer (PC). These tools significantly reduce troubleshooting time and sim-
plify report generation in the event of a system fault.
A faceplate RS232 port may be used to connect to a PC for the programming of settings and the monitoring of actual val-
ues. A variety of communications modules are available. Two rear RS485 ports allow independent access by operating and
engineering staff. All serial ports use the Modbus
with baud rates up to 115.2 kbps. The RS232 port has a fixed baud rate of 19.2 kbps. Optional communications modules
include a 10Base-F Ethernet interface which can be used to provide fast, reliable communications in noisy environments.
Another option provides two 10Base-F fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus
TCP, and TFTP protocols, and allows access to the relay via any standard web browser (C30 web pages). The IEC 60870-
5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time.
The C30 IEDs use flash memory technology which allows field upgrading as new features are added.

a) OVERVIEW
The C30 is available as a 19-inch rack horizontal mount or reduced-size (¾) vertical unit and consists of the following mod-
ules: power supply, CPU, CT/VT, digital input and output, transducer input and output, and inter-relay communications.
Each of these modules can be supplied in a number of configurations specified at the time of ordering. The information
required to completely specify the relay is provided in the following tables (see chapter 3 for full details of relay modules).
Order codes are subject to change without notice. Refer to the GE Multilin ordering page at
http://www.GEindustrial.com/multilin/order.htm
NOTE
The order code structure is dependent on the mounting option (horizontal or vertical) and the type of CT/VT modules (regu-
lar CT/VT modules or the HardFiber modules). The order code options are described in the following sub-sections.
