Siemens PXC Programmable Controller Modular PXC00-PE96.A BACnet

Description

The Siemens PXC Modular (Programmable Controller-Modular) PXC00-PE96.A is an advanced supervisory field controller created to streamline HVAC and facility management systems. Functioning as a central network coordinator, it collects system data from connected sensors and directly controls field devices without depending on a higher-level host processor. Its modular footprint allows industrial facilities and commercial setups to scale control capabilities according to operational requirements.

Main Features

• Supervisory DDC Control: Provides standalone or networked Direct Digital Control routines for facility-wide equipment.
• Network Integration: Built-in support for BACnet communication protocols over Ethernet (BACnet/IP) and MS/TP field networks.
• Adaptive Control Algorithm: Utilizes advanced closed-loop Adaptive Control that auto-adjusts to system load and seasonal shifts, reducing oscillation and wear on mechanical actuators.
• Data Retention & Battery Backup: Integrated battery backup preserves internal RAM database during extended power interruptions for up to 30 days.
• LED Diagnostics: Front-panel LEDs provide visual verification of system operation, network status, and battery health.

Benefits

• Scalable Investment: Modular construction enables businesses to start with essential supervisory components and expand network nodes as facility needs grow.
• Reduced Downtime: Fast processing combined with secure memory backup eliminates the risk of control logic loss during power supply failures.
• Optimized Energy Usage: Implements pre-programmed energy management sequences to minimize power consumption in commercial HVAC plants.
• Simplified Serviceability: DIN-rail mounting and quick-connect terminal points reduce setup time and routine maintenance efforts.

Applications

The unit is engineered for integration into central air-handling plants, chilled water management networks, multi-story commercial buildings, data centers, pharmaceutical environments, and industrial complexes requiring BACnet field-level supervision.

Key Features

• High-performance Direct Digital Control (DDC) supervisory field panel.
