ABB ACQ80-04 Series User Manual

• Tightening torques: 0.5…0.6 N·m (0.4 lbf·ft)
Notes
1)
Current [0(4)…20 mA, R
in
< 500 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm] input as
selected with parameter 12.15 AI1 unit selection.
2)
Current [0(4)…20 mA, R
in
= 100 ohm] or voltage[ 0(2)…10 V, R
in
> 200 kohm] input as
selected with parameter 12.25AI2 unit selection.
3)
Total load capacity of the auxiliary voltage output+24V (X2:10) = 6.0 W (250 mA / 24 V)
- User can use this source for either of theI/O connections (DI1... DI2- RO1 or DI3...DI6 -
RO2~RO3).
4)
Connected with jumpers at the factory.
5)
Applicable for R0~R2 frames only.
6)
Use shielded twisted-pair cables for digital signals.
7)
Ground the outer shield of the cable 360 degrees under the grounding clamp on the
grounding shelf for the control cables.
