Outline Of D/A Output; Terminal Names And Signal Names Of The D/A Output Terminal; Connecting D/A Output - KYOWA WGA-910A Series Instruction Manual

4-7. OUTLINE OF D/A OUTPUT

The setting contents of D/A output of the optional BCD and D/A output is the same as that of the optional D/A
output. (Refer to "2-6. D/A Output Set.")
In addition, the output circuit is insulated from the WGA-910A main circuit and the resolution is 14 bits equivalent.
(Output range: -10 to +10 V, 4 to 20 mA)
Conversion speed is 2000 times/sec.
NOTE
Covesion speed of the optional BCD and D/A is half as much as that of the optional D/A (model:
WGA-910A-2).

4-8. TERMINAL NAMES AND SIGNAL NAMES OF THE D/A OUTPUT TERMINAL

Terminal names (the following terminal names are described in order from left to right seeing from the back) and
signal names of the D/A output terminals are as follows.

4-9. CONNECTING D/A OUTPUT

Load resistance should be set as follows for connecting the external device.
Voltage Output: 2 kohm or more
Current Output: 500 ohm or less
<How to connect>
1) Peel off a jacket of a connecting wire approx. 10 mm and twist the tip of the wire for not to loosen.
Available wire range is
Single wire: φ0.4 mm (AWG26) to φ1.2 mm (AWG16),
Twist wire: 0.2 mm
2) Press the upper button hard with a slotted screwdriver.
Use the slotted screwdriver with blade diameter 3 mm and width of blade edge 2.6 mm (precision screwdriver,
etc).
3) Carefully insert the twisted wire to the lower hole.
4) Release the slotted screwdriver from the upper button and lightly pull the cable to check that the cable is securely
clamped.
NOTE
・For connecting more than 1-m long cable, use a twisted cable.
・For connecting more than 3-m long cable, use a 2-conductor shielded cable and always ground the shielded
cable to the ground terminal.
・In addition, for connecting more than 30-m long cable or using outdoors, take special countermeasures against
noise.
・Do not solder the wire or mount the press-fit terminal.
・Be sure to turn OFF the WGA-910A before connecting cables.
・For connecting multiple wires, twist them in advance. Check that the twisted wires are within the above range.
