CHAPTER 2 Checks and Preparation
(8) Voltage Output Module (GL7-DCO): Optional
This explains how to connect to the voltage output terminal.
+ ............ High-voltage terminal (Terminal for outputting the high-voltage side of the output signal)
– ............ Low voltage terminal (Terminal for outputting the low-voltage side of the output signal)
•
The external signal should not be input to the voltage output terminal.
•
During wiring, confirm that the power of the module is turned OFF.
•
The voltage output terminal on this module is not isolated. (GND terminal and common potential)
Also, - terminal (low-voltage) of each ch is connected to all ch.
Connection of Output Signal
When connecting between the voltage output terminal and equipment to be received, the SMA-BNC
conversion cable (B-562) sold separately should be used.
SMA connector
If you do not use the cable sold separately, always connect with the cable that conforms to SMA connector
specifications.
Do not apply the external voltage to the voltage output terminal. This module may be damaged.
•
During installation, a 4 kgf.cm screw tightening torque is recommended.
•
Do not short-circuit between the + side (high-voltage) and - side (low-voltage) of the voltage output terminal. This
module may be damaged.
•
When the power is turned on and off, the voltage may be output from the output terminal for 10 ms. If the GL7000 is
affected by the output voltage, please disconnect the output cable before the power is turned on or off.
•
The load current of the voltage output is ±10mA/ch (The total output current of the modules to be used must be ±
40mA or less.).
