Monitoring and Metering

The C30 provides high resolution measuring

of the status of external devices wired to its

contact inputs. The changing of a contact input

status can be measured

and time-stamped with a 0.5ms resolution,

making the C30 ideal for bay or substation SOE

recording.

Fault and Disturbance Recording

The advanced disturbance and event recording

features within the C30 can significantly reduce

the time needed for postmortem analysis

of power system events and the creation of

regulatory reports.

Advanced Device Health Diagnostics

The C30 performs comprehensive device health

diagnostic tests at startup and continuously

during run-time to test its own major functions

and critical hardware. These diagnostic tests

monitor for conditions that could impact security

and availability of protection, and present device

status via SCADA communications and front

panel display. Providing continuous monitoring

and early detection of possible issues help

improve system uptime.

Monitoring & Metering

• Advanced recording capabilities with highcapacity

event recorder, configurable and

extended waveform capture and data logger

• Metering: current, voltage, power, energy,

frequency, and harmonics

Protection and Control

As part of the UR family of Protection & Control

devices, the Multilin C30 offers a high degree

of modularity in its design and functionality,

providing superior performance while meeting

the toughest requirements of the marketplace.

Control, automation, I/O expansion and data

gathering are ideally suited for the C30 in the

following applications:

• Bay control

• Substation automation

• Remote I/O

Advanced Automation

The C30 incorporates advanced automation

features including powerful FlexLogic™

programmable logic, peer- to-peer

communications and SCADA capabilities that

far surpass what is found in the average PLC or

controller. The C30 integrates seamlessly with

other UR relays to extend the I/O capabilities and

perform complete bay management and control.

Applications

• Bay control and substation automation

• Programmable logic control

• UR I/O expansion

• Sequence of Events (SOE) recorder replacement

Protection and Control

• Programmable logic, timers, counters

• Distributed logic, remote I/O expansion

• User-definable protection elements

• Up to 96 digital inputs and 64 digital outputs

• Transducer I/Os (RTD, DCmA)

Advanced

Communications

• 3 independent Ethernet ports for simultaneous

& dedicated network connections with IEEE

1588 support

• Advanced IEC 61850 Edition 2 implementation

and IEC 61850-9-2 process bus support

• Supported industry protocols: IEC 61850 Ed.

2. SFTP, MMS File Transfer Service, DNP 3.0.

Modbus Serial/TCP, IEEE 1588. IEC 60870-5-

104 and 103. PRP, SNTP, HTTP, TFTP

• Direct I/O: secure, high-speed exchange of

data between UR relays for Direct Transfer

Trip and I/O extension applications

Cyber Security

• CyberSentry™ provides high-end cyber

security aligned to industry standards and

services (NERC® CIP, AAA, Radius, RBAC, Syslog)

changes to device configurations

Multilin™ C30

Substation Hardened Programmable

Logic Controller

The Multilin C30 controller system is a substation hardened device designed to perform substation

control logic that can also expand the I/O capability of protection devices and replace existing SOE

recorders. The C30 provides fast and deterministic execution of programmable logic with I/O capabilities

far above an average protection relay.

Graphical programming tools, supported by a library of logic operators, make the C30 simple to use

and configure. Using high-speed peer-to-peer communications for inter-device messaging, the C30 can

also accept signals and commands from other protection and control devices at a fraction of the cost

of hard-wiring these signals.

Key Benefits

• Powerful and deterministic programmable logic suitable for creating most customized automated

substation control solutions

• Modular hardware architecture allowing for flexibility in the I/O configuration to support most bay

management applications

• Reduced bay or station wiring through the use of high-speed peer-to-peer communication for sending

and accepting control commands from other relays

• Simplified system integration and access to information through the use of multiple communication

options and protocols not found in industrial grade PLCs

• Advanced IEC 61850 Ed. 2 implementation, complete settings via SCL files and IEC 61850-9-2 process

bus solution enable resource and platform managing optimization and reduce cost of ownership

• Increased network availability via failover time reduced to zero through IEC® 62439-3 “PRP” support

• CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP,

AAA, Radius, RBAC, Syslog)

• Advanced fault and disturbance recording, including internal relay operating signals, eliminating the

need for external recording devices
