22.2.19 IRIG-B time synchronization module IRIG-B
SEMOD141102-1 v1
22.2.19.1 Introduction
SEMOD141113-4 v7
The IRIG-B time synchronizing module is used for accurate time synchronizing of the IED from a
station clock.
The Pulse Per Second (PPS) input shall be used for synchronizing when IEC 61850-9-2LE is used.
Electrical (BNC) and optical connection (ST) for 0XX and 12X IRIG-B support.
22.2.19.2 Design
SEMOD141098-4 v3
The IRIG-B module has two inputs. One input is for the IRIG-B that can handle both a pulse-width
modulated signal (also called unmodulated) and an amplitude modulated signal (also called sine
wave modulated). The other is an optical input type ST for optical pulse-width modulated signal
(IRIG-B 00X).
