Performance and Feedback Modules

• The analog position feedback module provides a 4…20 mA signal with configurable split ranges.
• It supports two-wire circuitry with 24 V DC (10…30 V DC) or 48 V DC (20…48 V DC, no explosion protection).
• Action direction is configurable as direct or reverse.
• Characteristic deviation stays below 1 % for accurate positioning.
• Without a positioner signal, the module sets output to > 20 mA as an alarm level.
• The digital feedback module offers two switches, adjustable within 0…100 % range without overlap.
• Current circuits follow DIN 19234/NAMUR with supply voltage 5…11 V DC.
• Signal current < 1.0 mA means logical “0”; signal current > 2.0 mA means logical “1”.

Shutdown and Safety Functions

• A dedicated shutdown module works with 24 V DC (20…30 V DC), electrically isolated from the input signal.
• Safe position activates when voltage drops below 5 V.
• The module holds AK 4 approval to DIN V 19250 and test report No. 101/S01/148.
• Fail-safe mode depressurizes output 1 and moves the valve to its safe position.
• For double-acting actuators, fail-safe mode additionally pressurizes the second output.
• Fail-freeze mode closes pneumatic output 1 and keeps the valve in its current position.
• With double-acting actuators, fail-freeze mode closes both outputs.
• The shutdown module operates independently from the motherboard, so all final control element data remains available to the supervisory system.

Digital Position Feedback with Proximity Switches

• Two proximity switches provide independent position signaling.
• Switching points are adjustable between 0 and 100 %.
• Current circuits comply with DIN 19234/NAMUR.
• Supply voltage ranges from 5…11 V DC.
• Signal current < 1 mA represents logical “0”; signal current > 2 mA represents logical “1”.

Mounting and Installation Guide

• Mount the positioner to linear actuators according to DIN/IEC 534 / NAMUR.
• For rotary actuators, follow VDI/VDE 3845 mounting standards.
• The mechanical position indicator helps with visual alignment during setup.
• Use cable thread 1/2-14 NPT and air pipe thread 1/4-18 NPT for connections.
• Keep supply pressure within 1.4…6 bar (20…90 psi) for stable operation.
• Verify IP 65 / NEMA 4X protection remains intact after installation.
