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.)
When driving the unit with the power supply unit
connected to the SX-2000CI, connect the power
supply to this terminal via an optional RM-200RJ
Terminal Unit.
(See p. 12 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. Control Output Terminals
[CONTROL OUTPUT 1 – 32]
Relay make contact outputs.
Activating the control input terminal of the SX-
2000CI causes the control output terminal with
the same channel number to close.
Each contact capacity is rated at 40 V DC for
withstand voltage, and 2 mA – 300 mA for
control current.
13. CI/CO Link Through Switch [ON/OFF]
Normally, set this switch to the OFF position.
Note
This switch is set to "OFF" by default.
14. 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.
15. CI/CO Link Data Terminal [CI/CO LINK DATA]
Connect this terminal to the CI/CO Link Terminal
of the SX-2000CI.
Power to operate the unit cannot be supplied
through this terminal.
Refer to the table below for the indicators'
functions and status.
