Module 4475 is a Sub-Master Clock Module in a compact aluminium housing for 35mm DIN rail mounting (DIN EN 60715 TH35). The module is easily clipped onto the rail via a clip based on "snap-in" mechanism.

The synchronisation of Sub-Master Clock Module 4475 can be performed via the following signals:

Serial hopf Master/Slave string from a hopf Master Clock
DCF77 pulse (1Hz)
Module 4475 provides the below parameterizable signal outputs via the hmc (hopf Management Con-sole):

Serial interface COM0: RS232
Output of serial string, cyclic pulses, DCF77 pulse (1Hz) or
digital IRIG-B signal B00x / IEEE C37.118-2005 (formerly IEEE 1344-1995) / AFNOR NF S87-500 or connection to the hmc (hopf Management Console)
Serial interface COM1: RS232 or RS422 (level parameterizable via the hmc)
Output of serial string, cyclic pulses, DCF77 pulse (1Hz) or

analogue IRIG-B signal B12x / IEEE C37.118-2005 (formerly IEEE 1344-1995) / AFNOR NF S87-500
Optionally available with additional:
1x or 2x FO outputs
1x FO output and 1x FO input
for the output of a serial string, cyclic pulses, DCF77 pulse (1Hz) or
