Order number: 1MRK000838-HA
Category: Intelligent valve positioner/actuator controller (with network communication function)
System ownership: ABB process automation/actuator product line
ABB RXIDK 2H 1MRK000838-HA module
============================================
[One sentence positioning]
This is not a pressure transmitter, nor is it a relay or power board – it is ABB’s intelligent valve positioner, responsible for driving pneumatic/electric actuators to accurately move the valve to the designated position, while also having Ethernet communication and PID regulation capabilities.
============================================
[Core Function]
Dual channel analog control
Channel 1: Positioner Q control (AO output), driving the valve to the target position
Channel 2: Position monitoring (input A), real-time feedback of actual valve opening
Two channel independent configuration, closed-loop control
PWM modulation (three options available)
Random modulation/asynchronous modulation/synchronous modulation
Users can switch freely online and adapt to different execution mechanisms
Built in PID regulator
Equipped with PID algorithm, precise adjustment can be achieved without the need for external controllers
Output 24V DC power supply, simplify on-site wiring
Rich input interfaces
1 channel 5V analog input
2-channel optoelectronic isolated PWM pulse input (amplitude<12V)
2-channel current/voltage optoelectronic isolated analog input
Can directly connect to on-site signals such as flow signals and pressure signals
network communication
Embedded 10/100Mbps RJ45 Ethernet port
Supports Modbus TCP protocol
Up to 14 connections can be established simultaneously (compatible with software such as WINLDR, WINSRVOPC, HG interface, etc.)
Dynamic data transmission, supporting up to 255 data emails
Formula and Data Management
Built in formula and production method data, exported in CSV format
Easy to configure, debug, and maintain equipment
