        • Advanced Cross-Talk Noise Rejection: Boasting a cross-talk attenuation of > 100 dB, the circuit layout maintains signal purity even when parallel channels are driving massively different loads simultaneously.
        • Energy-Efficient Low Burden Optimization: Capable of pushing full 20mA signals into high 500 Ω loops while running cool, it minimizes internal heat dissipation inside closed, unventilated automation cabinets.
        • Native SolutionCenter Workspace Integration: Complete hardware parameters, scaling limits, and safety fallback states are quickly declared inside Bachmann's centralized software environment, removing the need for manual code logic.
        • Flexible Current Profile Scaling: Software registers allow the 2 output channels to be independently scaled for 0-20 mA or standard 4-20 mA configurations, accommodating a massive array of legacy and modern industrial field equipment.
        • Deterministic I/O Registry Mapping: Channel value assignments are coupled directly to the M200 controller’s deterministic real-time tasks, ensuring that analog updates match exact CPU clock cycle execution for jitter-free control.
        • Intelligent Error Handling & Failsafe Definitions: Programmers can pre-define specific fallback behaviors (such as Last Value Hold or Force to Zero) within the module's setup, protecting machinery if backplane communications ever drop.
        Description
        Empowered by an advanced 16-bit digital-to-analog converter architecture, the Bachmann AO202/SI ensures an ultra-fine value of LSB at 305 nA for driving field actuators, valves, and speed governors. This high-resolution feedback loop drastically minimizes control signal deviations, guaranteeing smooth and responsive process regulation across complex automation architectures. 

        Safety and signal integrity are at the core of the Bachmann AO202/SI design philosophy. Featuring a true "Single Isolated" (/SI) topography, the module provides 500 V of complete galvanic isolation both channel-to-channel and channel-to-system. This advanced barrier effectively eliminates ground loops, mitigates cross-talk down to > 100 dB, and safeguards the central PLC CPU against field-side voltage surges or electromagnetic interferences.

        Built to withstand the harshest environmental stressors, the Bachmann AO202/SI operates flawlessly within a wide temperature range of -30°C to +60°C and accommodates up to 95% non-condensing relative humidity. Backed by an extensive suite of elite maritime certifications including DNV, LR, ABS, and GL/BV, this module is the industry-standard choice for maritime propulsion, offshore wind farms, and critical heavy industry setups. 

        The Bachmann AO202/SI incorporates a reliable, short-circuit-proof output design capable of sustaining up to 500 Ω of burden impedance under continuous workloads. Fully integrated into Bachmann's diagnostic ecosystem, the module offers instantaneous status monitoring through its physical LED indicators and specialized engineering software, which shortens troubleshooting windows and maximizes overall plant uptime.

        VIEW ALL FAQS
        What is the maximum load resistance supported by the Bachmann AO202/SI current loops, and what happens if this limit is exceeded?
        The Bachmann AO202/SI supports a maximum loop burden of up to 500 Ω per channel. If the total impedance of your field wiring and actuator receiver exceeds 500 Ω, the module will be unable to drive the full 20 mA output current. This will trigger the internal short-circuit and open-loop diagnostics, registering a fault within the controller software due to saturation.
        How does the Bachmann AO202/SI handle channel diagnostics and software configuration inside the engineering workspace?
        The Bachmann AO202/SI utilizes internal hardware registries that communicate directly with the Bachmann SolutionCenter software environment.

        What specific wiring terminal blocks are required to connect the Bachmann AO202/SI to external field devices?
        The Bachmann AO202/SI relies on the specific "SS-AO202/SI B+C" accessory set, which carries the official Bachmann Part Number 00012378-50. This kit consists of a lateral Phoenix screw terminal block assembly (2x SS 35/03), pre-printed labeling strips, and dedicated mechanical keying elements to prevent incorrect slot insertion during maintenance.
        How does the channel isolation design of the Bachmann AO202/SI enhance cross-talk attenuation in multi-cable cable trays?
        The Bachmann AO202/SI features individual 500V galvanic isolation for each analog path, providing an outstanding cross-talk attenuation rating of greater than 100 dB within the 50 Hz to 60 Hz range. This means that even if the field cables of the Bachmann AO202/SI are routed tightly alongside high-power lines or adjacent signal cables, capacitive and inductive coupling between the two channels is virtually nonexistent.
        Is the Bachmann AO202/SI suitable for deployment in maritime automation and offshore environments?
        Yes, the Bachmann AO202/SI is fully type-approved for marine configurations by all major international marine classification societies, including DNV, ABS, Lloyd's Register (LR), Bureau Veritas (BV), and RINA. Its rugged electronic layout is designed to withstand the extreme vibrations, moisture, and thermal cycling common in marine propulsion control, ballast systems, and offshore wind substations.
        What are the strict environmental temperature and pollution limits for mounting the Bachmann AO202/SI module safely?
        The Bachmann AO202/SI is rated for an operational temperature range of -30°C to +60°C and a storage threshold of -40°C to +85°C. Mechanically, it complies with Pollution Degree 2 under IEC 60664-1 standards, meaning the Bachmann AO202/SI must be installed within an enclosure (such as an IP54 or IP65 cabinet) that protects the non-conductive internal circuitry from heavy condensation or dust accumulation.
