8. 230VAC:
The power cord is plugged in to the panel connector containing an integrated fuse (6A).
The device becomes active, when a voltage of 230V AC is applied
9. DC IN 24V:
The 24V DC power supply is connected to the terminal block. In case of a breakdown of the
230 V supply a switch to the 24V DC supply is carried out without interruption. As long as
a supply via 230V AC is made the power consumption at the 24V DC input is kept at a
minimum level (10mA for measurements).
10. OUT1:
Power output chanel 1 (Common / 50V / 100V)
11. OUT2:
Power output chanel 2 (Common / 50V / 100V)
12. OUT3:
Power output chanel 3 (Common / 50V / 100V)
13. OUT4:
Power output chanel 4 (Common / 50V / 100V)
14. CH 1/2 OK:
Potential-free optocoupler output, closed when channels 1 and 2 are ok. After switching on,
the contact remains open for a few seconds until the protection mode ends and the speaker
output
is
being
unlocked.
15. CH 3/4 OK:
Potential-free optocoupler output, closed when channels 3 and 4 are ok. After switching on,
the contact remains open for a few seconds until the protection mode ends and the speaker
output
is
being
unlocked.
16. AC 230V OK:
Potential-free octocoupler output, closed when 230V AC supply is ok.
17. DC 24V OK:
Potential-free octocoupler output, closed when 24V DC Versorgung is ok.
18. +IN1, GND, -IN1:
symmetric signal input for chanel 1
19. +IN2, GND, -IN2:
symmetric signal input for chanel 2
20. +IN3, GND, -IN3:
symmetric signal input for chanel 3
21. +IN4, GND, -IN4:
symmetric signal input for chanel 4
22. Pilottone:
asymmetric signal input for pilot signal chanel 1 and 2
23. Pilottone:
asymmetric signal input for pilot signal chanel 3 and 4
24. +IN 1/2 B, GND, -IN 1/2 B:
symmetric signal input for chanel 1/2 Bridge mode
25. +IN 3/4 B, GND, -IN 3/4 B:
symmetric signal input for chanel 3/4 Bridge mode
