ABB PHARPS3200000
ABB PHARPS3200000 Industrial-Grade Process Control Module (Specialized for High-Precision Analog Signal Conditioning & Control, Compatible with ABB Advant OCS/DCS Systems)
Product Description
The ABB PHARPS3200000 is a high-performance industrial process control module designed for critical analog signal processing and closed-loop control in industrial automation scenarios (e.g., chemical reactors, power plant steam systems, oil & gas pipelines). As a key component of ABB’s process control ecosystem, it synergizes with upstream control units such as the ABB PM875-2 PLC CPU module to form a “signal acquisition-conditioning-control-execution” integrated loop:
First, it receives raw analog signals (e.g., temperature, pressure, flow) from field sensors (4-20mA/0-10V). Through built-in high-precision signal conditioning circuits (including filtering, linearization, and isolation), it eliminates electromagnetic interference (EMI) and signal distortion caused by long-distance transmission. Then, it transmits the normalized signals to the PM875-2 CPU module for logic calculation. After receiving control instructions from the CPU, the PHARPS3200000 converts digital commands into analog output signals to drive actuators (e.g., control valves, variable frequency drives), realizing real-time adjustment of process parameters.
Equipped with channel-level fault diagnosis and redundancy support, the module can detect signal over-range, sensor open/short circuits, and internal component failures, while enabling “1+1” hot standby to avoid control interruptions. Its industrial-grade design ensures stable operation in harsh environments (high temperature, high humidity, strong EMI), making it ideal for high-reliability process control scenarios requiring precision and continuity.
