Electrical data for inputs and outputs

Note
When using the device in potentially explosive atmospheres,
note the additional connection data in Use in potentially
explosive atmospheres on page 5!
Analog input
Set point signal analog (two-wire technology)
Terminals +11 / −12
Nominal operating range 4 to 20 mA
Split range configuration 20 to 100 % of the nominal operating range can be
between parameterized
Maximum 50 mA
Minimum 3.6 mA
Starting at 3.8 mA
Load voltage 9.7 V at 20 mA
Impedance at 20 mA 485 Ω
Digital input
Input for the following functions:
•
no function
•
move to 0 %
•
move to 100 %
• Hold previous position
• block local configuration
• block local configuration and operation
• block any access (local or via PC)
Binary input DI
Terminals +81 / -82
Supply voltage 24 V DC (12 to 30 V DC)
Input 'logical 0' 0 to 5 V DC
Input 'logical 1' 11 to 30 V DC
Input Current maximum 4 mA
Digital output DO
Output configurable as alarm output by software.
Binary output DO
Terminals +83 / −84
Supply voltage 5 to 11 V DC
(Control circuit in accordance with DIN
19234/NAMUR)
Output 'logical 0' > 0.35 mA to < 1.2 mA
Output 'logical 1' > 2.1 mA
Direction of action Configurable
'logical 0' or 'logical 1'
Option modules
Plug-in module for analog feedback AO*
Without any signal from the positioner (e.g. 'no power' or
'initializing') the module sets the output to > 20 mA (alarm level).
Terminals +31 / −32
Signal range 4 to 20 mA (split ranges can be parameterized)
• in the event of an error > 20 mA (alarm level)
Supply voltage, two-wire 24 V DC (11 to 30 V DC)
technology
Characteristic curve rising or falling (configurable)
Deviation < 1 %
Plug-in module for digital feedback SW1, SW2*
Two software switches for binary position feedback (position
adjustable within the range of 0 to 100 %, ranges cannot
overlap)
Terminals +41 / −42, +51 / −52
Supply voltage 5 to 11 V DC
(Control circuit in accordance with DIN 19234 /
NAMUR)
Output 'logical 0' < 1.2 mA
Output 'logical 1' > 2.1 mA
Direction of action Configurable
'logical 0' or 'logical 1'
* The module for analog feedback and the module for digital feedback have
separate slots and can be used together.
