Analog Output Module Terminal Arrangement
FC3A-DA1221 (2-channel Analog Output Module) — Screw Terminal Type
Applicable Connector:
SMSTB2.5/20-ST-5.08 (Phoenix Contact)
Wiring Example:
Suppose that an analog output module is the sixth functional module installed in the
OpenNet Controller
system. To gener-
ate a 4V analog output voltage from channel 1 using the 0 to 5V output range, set the rotary switch to 2 and store a digital
value of 3200 to link register L601, which is assigned to channel 1 of the sixth functional module.
Because 5V
×
3200/4000 = 4V, digital value 3200 is converted to an analog value of 4V and outputted to terminals 15 and
16 of the analog output module.
For wiring schematic and precautions, see page 3-8.
Notes:
•
Before mounting the analog output module, first set the rotar y switch to meet the required analog output range. After set-
ting the rotar y switch, power up the CPU and other modules.
•
The COM (GND) terminals of each channel are connected together internally.
