2.3.2.10 GPIO Controlling Module RM330-310/ 311
2.3.2.11 Synchronization Module RM330-410
•
8 relay contacts (noiseless semiconductor
relays RM330-310, electro-mechanical
relays RM330-311)
•
Max. 300mA/ 48V per relay contact
•
4 optical switch inputs (input voltage 5V -
25V, current consumption approx. 5mA,
scanning cycle 20ms)
•
15-pin Sub-D-socket (male) with current-
limited auxiliary voltage for the 4 optical
inputs
•
2 analog potentiometer inputs

•
BNC input for TTL-wordclock or AES3/EBU-
signal as synchronization source for the
system (only on slot 1)
•
BNC output for TTL-wordclock (operates
with the current system sampling frequency)
•
Per jumper switchable phase inversion for
the in- and outputs of the TTL- wordclock
(refer to section
Jumper Settings on
page 172
)
•
High accuracy PLL circuits for 44.1kHz and
48kHz with ±75ppm locking range and low
accuracy PLL circuit with 30...48.5kHz
locking range
•
internal quartzes 44.1kHz and 48kHz,
accuracy ±10ppm for 44.1kHz and 48kHz
