5.4.3.2 Control terminals on OPTA1
Here you see the basic description of the terminals of the I/O board and the relay board. For more
information, see Jumper selections on the OPTA1 basic board. For more information on control
terminals, see VACON

Figure 48. The control terminal signals in OPTA1
*) See Fig. 26 Jumper blocks on OPTA1.
Parameter references for I/O on keypad and NCDrive are: An.IN:A.1, An.IN:A.2, DigIN:A.1, DigIN:A.2,
DigIN:A.3, DigIN:A.4, DigIN:A.5, DigIN:A.6, AnOUT:A.1 and DigOUT:A.1.
To use the control voltage output +24V/EXT+24V:
• you can wire the +24V control voltage to digital inputs through an external switch.
• you can use the control voltage to power up external equipment, such as encoders and
auxiliary relays.
Note that the specified total load on all available +24V/EXT+24V output terminals must not exceed
250mA. The maximum load on the +24V/EXT+24V output per board is 150mA.
