Electrical data for inputs and outputsNote
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 between 20 to 100 % of the nominal operating
range can be parameterized
Maximum 50 mA
Minimum 3.6 mA
Starting at 3.8 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
Binary output
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

Direction of action Configurable
‘logical 0’ or ‘logical 1’
Option modules
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 technology 24 V DC (11 to 30 V DC)
Characteristic curve rising or falling (configurable)
Deviation < 1 %

5 Installation
Electrical connections

‘logical 0’ or ‘logical 1’
Description 2 software switches for binary position
feedback (position adjustable within
the range of 0 to 100 %, ranges cannot
overlap)
* The module for analog feedback and the module for digital feedback have
separate slots and can be used together.

Mechanical position indicator
Indicator disk in enclosure cover linked with device feedback
shaft.
These options are also available for retrofitting by Service.
2 tap holes ½- 14 NPT or M20 × 1.5 are provided on the left side
of the housing for cable entry in the housing. One of the tap
holes is fitted with a cable gland, while the other tap hole has a
blind plug.
Note
The connecting terminals are delivered closed and must be
unscrewed before inserting the wire.
1. Strip the wires to approximately 6 mm (0.24 in).
2. Connect the wires to the connecting terminals in line with the
connection diagram.
