Features and functions
Operation commands and setpoint via fieldbus interface
Control fieldbus
(input signals)
●
Via opto-isolator, with one common
●
Control voltage 24 V DC, current consumption: approx. 15 mA per input
●
Minimum pulse duration for shortest operation pulse: 100 ms
●
All digital inputs must be supplied with the same potential.
●
All inputs can be configured as required
●
Standard assignment (without positions and without fieldbus interface):
CLOSE, OPEN, STOP
●
Assignment for option with positioner:
MODE, CLOSE, OPEN
●
Assignment for option with fieldbus interface:
OPEN, CLOSE, I/O interface
I/O interface: Selection of the control source (fieldbus interface or I/O input signals)
Factory setting of “I/O Interface” signal: Input signal 0 V = fieldbus interface is active
3 digital in-
puts:
I/O interface control
(input signals)
●
0/4 – 20 mA or 0 – 10 V
●
No galvanic isolation
●
For option with positioner: Used as input signal for position setpoint or as input signal
for motor speed
●
For option with fieldbus interface: Used as input for the position setpoint (definition
via 2 digital inputs which command source is active for the positioning: fieldbus or
analogue input) or for a sensor signal which can be further transmitted via fieldbus.

Via fieldbus interface
Status signals fieldbus
(output signals)
●
Freely configurable semi-conductor output contacts, per contact max. 24 V DC, 100 mA
(resistive load)
●
Outputs can be configured as required
●
Standard assignment:
End position CLOSED (high active), end position OPEN (high active), collective fault
signal (low active)
3 digital out-
puts:
Status signals of I/O interface
(output signals)
●
Position feedback signal 0/4 – 20 mA (load maximum 500
Ω
) or 0 – 10 V
●
No galvanic isolation
Analogue
output:
Auxiliary voltage 24 V DC, max. 80 mA for supply of control inputs, without galvanic isolation.
Voltage output (option)
