Details：
The Yokogawa AAI835-S00 is a dual-function Analog Input/Output (I/O) Module, specifically designed for Yokogawa’s CENTUM VP and ProSafe-RS Distributed Control Systems (DCS). It integrates analog signal acquisition and output in one unit, serving as a compact interface between the DCS and field devices (e.g., sensors, transmitters, actuators). It is ideal for space-constrained industrial environments like small-scale process units or skid-mounted systems, widely used in sectors such as petrochemicals, water treatment, and food processing.
-----Core Specifications
The Yokogawa AAI835-S00 is classified as a combined analog I/O module, optimizing space by merging input and output functions. It features 4 analog input channels and 4 analog output channels—all independently isolated—to prevent cross-signal interference and ensure stable simultaneous operation.
For input signals, it supports common industrial types: 4-20 mA DC current (for transmitters like pressure or flow sensors) and 1-5 V DC voltage, with optional compatibility for thermocouple (TC) and resistance temperature detector (RTD) signals for temperature measurement. Input impedance is 250 Ω for current signals and 2 MΩ for voltage signals, matching standard field device output characteristics.
For output signals, it offers 4-20 mA DC current (standard) and 1-5 V DC voltage (standard), with optional 0-20 mA DC (current) and 0-10 V DC (voltage) ranges to adapt to diverse actuators (e.g., control valves, pumps). 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 loads.
Isolation performance meets industrial safety standards: 1500 V AC isolation between input/output channels and the system backplane (tested for 1 minute), and 250 V AC isolation between individual channels (tested for 1 minute) to resist electromagnetic interference (EMI).
Power supply uses a 24 V DC industrial standard (±10% tolerance to handle minor voltage fluctuations), with a maximum power consumption of 3.2 W when all 4 input and 4 output channels are active.
