10. Functional Earth Terminal [SIGNAL GND]
Hum noise may be generated when external
equipment is connected to the unit. Connecting
this terminal to the functional earth terminal of
the external equipment may reduce the hum
noise.
Note:
This terminal is not for protective earth.
11. DC Power Input Terminal [DC POWER IN]
Connect an optional AD-011 or AD-031B DC
Power Supply Panel to this terminal.
Select the appropriate panel taking into
consideration the total current consumption of all
equipment to be connected to the power supply
unit. (See p. 10.)
When not using a redundant power system*,
connect the [+] terminal of input A to the [+]
terminal of input B, and the [–] terminal of input A
to the [–] terminal of input B.
(See p. 11 and p. 13.)
* A method of connecting separate power
sources to each power input or connecting the
commercial power supply and backup power
supply separately to each power input to
prevent the system from going down when a
cable is broken or power fails.
12. 24 V DC Output Terminal [DC 24 V OUT]
This terminal supplies 24 V DC, max. 100 mA to
connected external equipment.
13. Control Input Terminals
[CONTROL INPUT 1 – 32]
Photo coupler inputs. A current of approximately
2 mA flows when shorted, and the voltage
becomes approximately 24 V DC when opened.
Activating the control input terminal causes the
control output terminal with the same channel
number (SX-2000CO) to close (provides make
contact).
14. CI/CO Link Through Switch [ON/OFF]
Normally, set this switch to the OFF position.
Note
This switch is set to "OFF" by default.
15. CI/CO Link Through Terminal
[CI/CO LINK THROUGH]
This terminal is not used.
Refer to the table below for the indicators'
functions and status.
16. CI/CO Link Data Terminal [CI/CO LINK DATA]
Connect this terminal to the CI/CO Link Terminal
of the SX-2000CO.
Refer to the table below for the indicators'
functions and status.
