Digital Valve positioner RE 3447

Product catalog summary

Overview
The document provides technical specifications and operational details for the digital positioner used with ST 5100 series electric actuators. It highlights the key features, technical data, mounting instructions, and functional description of the positioner.

Specifications

Input/Output Signals: The positioner accepts input signals of (0)4..20mA or (0)2..10V and provides output signals of (0)4..20mA, with galvanic isolation.
Control and Feedback: It includes bounce-free keys for manual operation and a potentiometer of 1KΩ. Feedback signals are also galvanically isolated.
Display and Output: LED indicators are used for display, and the output is managed through solid state relays (SSR) with a maximum capacity of 250V/50/60 Hz and 3.5A.
Power Supply: The device operates on a power supply range of 90-265V AC or 24V DC, with a power consumption of 3VA.
Environmental Conditions: It is designed to operate within an ambient temperature range of -10°C to +70°C.

Mounting Instructions
The positioner is mounted vertically within the actuator using a mounting bracket. It is recommended to use shielded wires for input and feedback signals to ensure signal integrity.

Functional Description

Microcontroller-Based Operation: The positioner is based on a microcontroller, allowing for advanced control features.
Auto-Initialization: It includes an auto-initialization function for easy adaptation to the actuator and valve.
Manual and Automatic Control: The device provides keys for switching between manual and automatic modes, as well as open/close operations.
Signal Selection: Input and feedback signals can be selected via a micro switch without the need for re-initialization.
Safety Features: The positioner includes a safety position feature that activates in case of signal loss or fault, and a close tight function to ensure secure valve closure.

Wiring and Dimensions
The document includes a wiring diagram and dimension sheet for installation guidance. Technical alterations are subject to change without notice.
