Power and consumption values
Binary inputs and outputs
binary inputs - Control inputs OPEN, CLOSED, STOP, Emergency and Mode (Emergency and Mode only on PROFITRON)
binary outputs - 8 binary electronic outputs for signals on PROFITRON, 5 outputs on ECOTRON
All binary inputs and outputs are galvanically isolated and potential-free.
Exception: For ECOTRON with relay board, the binary outputs refer to the potential of the electronics.
Binary outputs are resistant to both short-circuits and overloads.

Analog inputs and outputs
analog inputs - AE1: 0/4-20mA
- AE2: 0/4-20mA (add-on PCB)
analog outputs - AA1: Position actual value
(0/4-20mA) active, i.e. with internal power supply 24 V DC
- AA2: Position actual value
(0/4-20mA) passive, i.e. with external power supply 24 V DC (add-on PCB)
Analog inputs and outputs are galvanically isolated (only PROFITRON).
AE2 and AA2 are located on a common add-on PCB and have the same potential.
For existing add-on PCB (AE2+AA2), assignment of AE1 and AE2 analog inputs as well as AA1 and AA2 analog outputs is freely programmable.
Analog outputs are resistant to both short-circuits and overloads.

Ranges 0-20mA or 4-20mA with rising or falling level can be adjusted for PROFITRON; for ECOTRON, the curve is rising (4-20mA).
Relay outputs
Relay outputs are galvanically isolated.

The PROFITRON relay board has 8 relay outputs (5 NO, 1 NC and 2 change-over contacts), the 5 relay outputs of the ECOTRON are all designed as
change-over contacts.
Internal 24 V power supply
Only for PROFITRON are the binary inputs and outputs galvanically isolated from the electronics in case of internal 24V DC power supply
via „P24 gal.“.
External 24 V power supply
During power failure, both actual position value and device state are still sent via the external 24V DC supply „P24 ext.” to the binary
signal outputs (signals 1-8) and communication via COM-SIPOS or fieldbus is available.
During mains operation, own supply via actuator.
