The CCC (Compressor Controls Corporation) MCP-1004 is an industrial-grade circuit control board (CPU module) specially designed for centrifugal and axial compressors. Serving as the core arithmetic and logic control unit of the compressor control system, it is widely applied in the oil & gas, chemical, power and other industries. It undertakes critical functions including compressor anti-surge control, performance regulation, start-stop interlock and fault diagnosis, featuring high computing power, superior environmental adaptability and multi-protocol compatibility.
Core Functions
Compressor Core Control: Performs adaptive anti-surge control (real-time flow/pressure monitoring and dynamic anti-surge valve regulation), closed-loop pressure and flow regulation, start-stop sequence control, and load balancing distribution to ensure efficient and stable compressor operation.
Multi-parameter Monitoring and Protection: Collects real-time signals of temperature, pressure, vibration, rotational speed and other data. Built-in protection logic for over-temperature, over-pressure, surge and excessive vibration triggers alarms or interlock shutdowns to secure equipment safety.
High-speed Logic and Timing Control: Integrated with a TPU timing processor and equipped with 16 independent high-speed timing channels to execute complex interlocks and timing tasks, with a control command delay of ≤1ms.
Data Interaction and System Integration: Features multi-channel communication interfaces (MCCI), including SPI, SCI (UART) and QADC (10-bit analog-to-digital conversion). Compatible with Modbus RTU, Profibus, Ethernet/IP and other protocols, enabling seamless connection to DCS/PLC systems.
Fault Diagnosis and Maintenance: Embedded fault code library enables real-time hardware and software fault diagnosis and event log recording. It supports remote monitoring and debugging to reduce downtime.

FAQ
Q1: What is the difference between the MCP-1004 and ordinary PLCs?A1: The MCP-1004 is a compressor-dedicated CPU module with built-in patented CCC anti-surge algorithms. It is optimized for compressor-specific conditions such as surge, vibration and pressure fluctuation. General-purpose PLCs require customized secondary programming for complex anti-surge control, and lack sufficient computing power and real-time performance.
Q2: What is the operating temperature range? Can it start at -30°C?A2: The official operating temperature range is -40°C to +70°C. It supports low-temperature startup at -40°C without preheating, suitable for outdoor compressor stations and cold high-altitude regions.
Q3: How to communicate with a DCS system? What protocols are supported?A3: Modbus RTU is standard; Ethernet/IP and Profibus-DP gateway modules are optional. It connects to DCS via RS-485 or Ethernet for seamless data exchange, enabling remote monitoring and parameter modification.
Q4: Does it support redundant configuration?A4: It supports dual hot standby redundancy. Master/slave MCP-1004 modules can be configured for bumpless automatic switchover upon main module failure, ensuring continuous and uninterrupted compressor operation in compliance with industrial safety standards.
