Details：
The Yokogawa MAC2*C is a high-density Multipoint Analog Control Card, exclusively designed for integration with Yokogawa’s CENTUM VP Distributed Control System (DCS). It specializes in centralized analog control for multiple process loops—simultaneously handling signal acquisition, control logic execution, and output command generation—making it ideal for large-scale industrial processes like petrochemical reactors, power plant boilers, and water treatment systems where multi-loop control efficiency is critical.
-----Core Specifications
The Yokogawa MAC2*C is categorized as a multi-channel analog control card, optimized for high-density process loop management. It features 16 analog input channels and 8 analog output channels, all independently isolated to prevent cross-loop interference and ensure stable simultaneous operation of up to 8 independent control loops (each loop typically uses 2 inputs + 1 output).
For analog inputs, it supports standard industrial signals: 4-20 mA DC (for transmitters like pressure, flow, or level sensors) and 1-5 V DC, with optional compatibility for thermocouple (TC) signals (J, K, T types) and resistance temperature detector (RTD) signals (Pt100) for direct temperature-based control. Input impedance is 250 Ω for current signals and 2 MΩ for voltage signals, matching field device output characteristics.
For analog outputs, it provides 4-20 mA DC current (standard) and 1-5 V DC voltage (standard), with an optional 0-20 mA DC current range to drive actuators like control valves or variable-frequency drives (VFDs). Output load capacity is up to 500 Ω for current signals and a minimum of 10 kΩ for voltage signals, ensuring compatibility with most industrial actuators.
Isolation performance meets strict safety standards: 2000 V AC isolation between the card and DCS backplane (tested for 1 minute), and 500 V AC isolation between individual channels (tested for 1 minute) to suppress electromagnetic interference (EMI) from nearby power equipment.
Power supply relies on a 24 V DC industrial standard (with ±15% voltage tolerance to handle unstable grids), and maximum power consumption is 5.5 W when all 16 inputs and 8 outputs are active—suitable for high-density DCS rack configurations.
