Key Features:
- Signal Flexibility – Per-channel software configuration for voltage/current without hardware jumpers.
- Ultra-High Precision | 16-bit ADC with auto-calibration and drift compensation.
- Diagnostics | Wire break, over-range, calibration fault, and module health alarms.
- Noise Immunity | Integrated EMI/RFI filtering and galvanic isolation.
- Hot-Swap Capability | Live insertion/removal in RX3i backplanes.
- Compact Form | 2-slot width (half the size of legacy modules).
Primary Function & Purpose:
Converts industry-standard analog signals into high-resolution digital values for:
- Real-time process monitoring (pressure, flow, level, etc.).
- Closed-loop control of actuators, valves, and drives.
- Predictive maintenance through signal trend analysis.
Typical Applications:
- Process Instrumentation – Pressure transmitters, flow meters (4-20mA signals).
- Motor Control Centers – VFD feedback, load monitoring (0-10V).
- Tank Farm Management – Level sensors in oil/chemical storage.
- Water Treatment – pH/conductivity analyzer inputs.
- Test Benches – Calibration systems for analog devices.
Application Fields:
Critical for multi-sensor industrial automation in:
- Chemical Processing: Reactor pressure monitoring, additive dosing control.
- Power Generation: Turbine governor feedback, fuel flow measurement.
- Manufacturing: Robotic position feedback, hydraulic pressure control.
- Mining: Conveyor load cells, slurry density sensors.
- Renewables: Wind turbine pitch control, solar inverter telemetry.
