Description

SIEMENS PXC36-E.A Building Automation Programmable Controller

Product Dimensions：

The Siemens PXC36-E.A is a compact, high-performance automation station belonging to the Desigo PX building control system family. It is specifically designed to manage primary HVAC plants and large distribution systems with native BACnet/IP communications.

Product Overview

The PXC36-E.A functions as a standalone BACnet/IP controller with integrated onboard I/O points (36 physical points total). The “-E” in the model designation denotes native Ethernet/IP connectivity, while the “.A” indicates the specific hardware revision. It manages complex control strategies, schedules, alarm processing, and trend logs independently of a master server.

Technical Specifications

Key Product Advantages

• High Onboard Density: Built-in 36 physical I/O points reduce the need for external expansion modules, making it cost-effective for medium-sized plant rooms.
• Native BACnet/IP: Delivers high-speed communication over standard Ethernet networks, enabling rapid response times for monitoring and control commands.
• Autonomous Processing: Includes an onboard real-time clock (RTC), scheduling engines, trend logs, and alarm history—continuing full operational logic even if central network communications drop.
• Fully Programmable: Flexible control logic designed using Siemens Desigo Xworks Plus, enabling customized strategies for complex plant control.
• Seamless BMS Integration: Integrates effortlessly into Siemens Desigo CC or third-party BACnet Building Management Systems (BMS).

Important Considerations & Warnings

• Power Supply Quality: Always use a dedicated, isolated 24 V AC safety transformer (SELV/PELV). Do not connect 230 V AC main power directly to the unit terminals.
• I/O Channel Configuration: Ensure software point types (e.g., 4–20 mA vs 0–10 V DC) match the physical wiring jumper settings on universal channels before energizing field devices.
• IP Network Addressing: Ensure static IP addresses or appropriate DHCP reservations are configured via the Setup & Service Assistant (SSA) during commissioning to prevent loss of connection on the BACnet network.
• Environmental Shielding: Mount inside an IP54-rated metal enclosure when installed in dusty or humid mechanical rooms to protect terminal contacts.

Product Applications

• Air Handling Units (AHUs): Complete control of large multi-zone AHUs (heating, cooling, fan speed, damper actuators).
• Central Boiler Plants: Managing boiler staging, burner modulation, pumps, and primary loop mixing valves.
• Chiller Plant Control: Coordinating chiller sequencing, condenser pump control, and cooling tower fan speeds.
• District Heating Stations: Precise heat exchanger supply-temperature control based on ambient outdoor resets.
