ABB ACS880-07C, Hardware Manual

Page: 96 / 188

96 Control unit of frames R6 to R9
Digital inputs/outputs DIO1
and DIO2
(XDIO:1 and XDIO:2)
Input/output mode selection
by parameters.
DIO1 can be configured as a
frequency input (0…16 kHz
with hardware filtering of 4
microseconds) for 24 V level
square wave signal
(sinusoidal or other wave form
cannot be used). DIO2 can be
configured as a 24 V level
square wave frequency
output. See the firmware
manual

(14 AWG)
Input voltage range: -3…30 V DC
Logic levels: “0” < 5 V, “1” > 17 V
For the drive to start, both connections must be closed (OUT1 to IN1 and
IN2).
Current consumption of frames R1 to R7: 12 mA (+24 V DC, continuous) per
STO channel
Current consumption of frames R8 and R9: 30 mA (+24 V DC, continuous)
per STO channel
EMC (immunity) according to IEC 61326-3-1
Control panel / PC
connection Connector: RJ-45
Cable length < 3 m (10 ft)
The terminals on the board fulfil the Protective Extra Low Voltage (PELV) requirements. The PELV
requirements of a relay output are not fulfilled if the relay is used with a voltage higher than 48 V.
