Product Description

The AI815 is an 8-channel analog input module specifically engineered for 0(4) to 20 mA current loops. It is a non-isolated module, meaning all 8 channels share a common ground. The module performs high-resolution analog-to-digital conversion, allowing the control system to accurately monitor process variables such as pressure, temperature, flow, and level. It features a compact, modular design that snaps onto a Terminal Base (such as the TU810 or TU814), which allows for “Hot Swap” capability (removal/insertion under power) without disturbing the rest of the I/O cluster.

Product Parameters

The following technical specifications are standard for the AI815 module:

Product Advantages

• High Density: Provides 8 channels in a very slim form factor, saving significant space within the control cabinet.

• Cost-Effective: Ideal for applications where galvanic isolation between individual channels is not required, offering a lower price point per point.

• Hot Swap Capability: Supports “Run-and-Replace” functionality, allowing maintenance teams to replace a faulty module without shutting down the entire system.

• Accuracy and Speed: Features high-speed A/D conversion and 12-bit resolution, ensuring precise data for critical control loops.

• Robust Diagnostics: Includes LED indicators for “Fault” and “Run” status, along with digital reporting of over-range/under-range and hardware errors to the controller.

Safety and Maintenance Precautions

• Common Grounding: Because the channels are not individually isolated, ensure that all connected field devices are either isolated themselves or share a compatible ground potential to avoid ground loops.

• Terminal Base Selection: The AI815 must be paired with the correct Terminal Base (e.g., TU810, TU812, or TU814). Incorrect pairing can lead to wiring errors.

• Current Limiting: Ensure the input current does not exceed the maximum rated limit (typically 30 mA) to prevent permanent damage to the internal shunt resistors.

• ESD Protection: Always handle the module using anti-static procedures. Sensitive CMOS components can be damaged by static discharge.

• Firmware Sync: Verify that the I/O module version is supported by your Controller’s firmware version (e.g., AC800M).

Product Applications

The AI815 is a versatile module used across various sectors for general-purpose analog monitoring:

• Water & Wastewater: Monitoring tank levels, flow rates in pipes, and chemical dosing concentrations.

• Manufacturing: Interfacing with pressure transducers on hydraulic presses or pneumatic systems.

• HVAC Systems: Monitoring ambient temperature and humidity sensors in large industrial complexes.

• Food & Beverage: Tracking weight scales and flow meters on production lines.

• Energy Management: Reading power transducers or fuel level sensors for backup generators.
