3.4 Inputs
The Digital Data Interface features two integrated sensors and nine connections for ex-
ternal sensors.
Internal sensors (onboard)
ƒ
Temperature
Records the current temperature of the Digital Data Interface module.
ƒ
Vibration
Records the current vibrations at the Digital Data Interface along three axes.
Internal sensors (in motor)
ƒ
5x Temperature (Pt100, Pt1000, PTC)
ƒ
2x Analogue inputs 4-20 mA
ƒ
2x Inputs for vibration sensors (at max. 2 channels)
3.5 I/O modules – additional inputs
and outputs
A host of measuring data is required to control the pump/frequency converter combin-
ation (LPI system mode) or the complete system (LSI system mode). Usually the fre-
quency converter provides a sufficient number of analogue and digital inputs and out-
puts. If required, inputs and outputs can be supplemented by two I/O modules:
ƒ
Wilo IO 1 (ET-7060): 6x Digital inputs and outputs
ƒ
Wilo IO 2 (ET-7002): 3x Analogue and 6x digital inputs, 3x digital outputs
NOTICE
Wilo IO 2 for LSI system mode is mandatory!
Include Wilo IO 2 (ET-7002) in system planning to record all required measured val-
ues! System control is not possible without Wilo IO 2.

DANGER
Risk of death due to electrocution!
Improper conduct when carrying out electrical work can lead to death due to electric
shock! Electrical work must be carried out by a qualified electrician in accordance
with the locally applicable regulations.
