1MRK002305-AAr01 time synchronization module

Product manual:

Product Name: 1MRK002305-AAr01 Time Synchronization Module
type: Time synchronization unit/module
Manufacturer: ABB
Applicable system: Used for ABB power automation systems, especially relay protection devices and digital substation systems (such as 670 series IEDs)

1、 Core functions
Time synchronization management

Receive external standard time signals (such as IRIG-B, SNTP/NTP, 1PPS, etc.) to provide a unified time reference for protection devices and measurement units.

Coordinated operation with upper level clock source

The entire station clock can be synchronized through GPS receiver, master clock device, and SCADA system.

Support multiple time protocol inputs

Usually supports IRIG-B (serial/parallel), SNTP/NTP (Ethernet), 1PPS (pulse) and other methods.

2、 Application Fields
Relay protection devices (such as REL670, REF615, RET670)

Provide a time reference for internal logical operations and event recording to ensure the accuracy of operation timing.

Digital Substation Automation System (IEC 61850 Environment)

Support station level and interval level device time synchronization, synchronizing MMS messages and GOOSE communication timestamps.

Fault recording system (DR, DFR)

Ensure the accuracy of time labels in the recorded data, providing a basis for subsequent analysis and scheduling.

Control and Monitoring System (SCADA)

Provide high-precision time signals to synchronize the operation of each unit in the station control layer system.

3、 Technical characteristics (typical parameters)
Support time input protocols: IRIG-B (B000, B120), SNTP/NTP, 1PPS

Output accuracy: up to microsecond level time synchronization accuracy

Interface form: BNC, RJ45, optoelectronic isolation input, etc. (depending on the device version)

Installation method: Modular plug-in card, installed on the back panel of the relay protection equipment chassis

Working temperature range: Industrial grade -40 ° C to+70 ° C

Electromagnetic compatibility: compliant with standards such as IEC 60255 and IEC 61000
