… 7 Electrical connections
… Electrical data for inputs and outputs
Option modules
Module for analog feedback AO*
Only for devices with HART® Communication.
Without any signal from the positioner (e.g. ‘no power’ or
‘initializing’) the module sets the output to > 20 mA (alarm level).
Ter31 / − 32
Signal range 4 to 20 mA
(Parameterization on split-ranges
possible)
• 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 %
* The module for analog feedback and the module for digital feedback have
separate slots and can be used together.
Module for digital feedback SW1, SW2*
Only for devices with HART® Communication.
Ter41 / − 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’
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.
Assembly kits for digital feedback
Two proximity switches or microswitches for independent
signaling of the actuator position, switching points are
adjustable between 0 to 100%
Digital feedback with proximity switches Limit 1, Limit 2*
Ter41 / − 42, +51 / − 52
Supply voltage 5 to 11 V DC
(Control circuit in accordance with DIN
19234/NAMUR)
Signal current < 1 mA Switching state logical ‘0’
Signal current > 2 mA Switching state logical ‘1’
Direction of action
Actuator position
Proximity switch < Limit 1 > Limit 1 < Limit 2 > Limit 2
SJ2-SN (NC) 0 1 1 0
Digital feedback with 24 V-proximity switches Limit 1, Limit 2*
Terminals 41 / 42 / 43
51 / 52 / 53
Supply voltage maximum 24 V AC/DC
Load rating Maximum 2 A
Contact surface 10 µm Gold (AU)
* The proximity switches or 24 V microswitches for digital feedback are
activated directly via the positioner axis and can only be used in
combination with the optionally available mechanical position indicator.
Mechanical position indicator
Indicator disk in enclosure cover linked with device feedback
shaft.
These options are also available for retrofitting by Service.
