115
Volt
50/60
50/60

Permissible variation of mains voltage: ±10 %
Permissible variation of mains frequency: ±5 %
For current consumption, current type, mains voltage and frequency, refer to the name plate
Power supply
24 V DC +20 %/–15 %
Current consumption: With options up to 200 mA
The external power supply must have a reinforced insulation against mains voltage in accord-
ance with IEC 61800-5-1 and may only be supplied by a circuit limited to 150 VA in accordance
with IEC 61800-5-1.
External supply of the electron-
ics (option)
Category III according to IEC 60364-4-443
Overvoltage category
Power electronics with integral motor controller
Power electronics
The controls are designed for the rated motor power, refer to name plate
Rated power
●
4 digital inputs (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.
Assignment for open-close actuators:
-
OPEN, STOP, CLOSE (standard)
-
OPEN, STOP, CLOSE, EMERGENCY (option)
-
OPEN, STOP, CLOSE, MODE in combination with positioner (option)
-
OPEN, EMERGENCY, CLOSE, MODE in combination with positioner (option)
Assignment for modulating actuators:
-
OPEN, STOP, CLOSE, MODE (standard)
-
OPEN, EMERGENCY, CLOSE, MODE
●
Analogue input 0/4 – 20 mA (galvanically isolated)
Used as input signal for position setpoint E1 (in combination with positioner) or as input
signal for motor speed E3.
Control
(input signals)
●
Output contacts:
