Key Features

1. High-Density 10-Input/2-Output Design: Integrates 10 software-configurable analog inputs and 2 precision analog outputs, reducing system footprint and wiring complexity.
2. Multi-Range Signal Compatibility: Supports voltage (±5 V, ±10 V) and current (±1 mA, 0–20 mA, 4–20 mA) inputs, accommodating diverse field sensors (transmitters, thermocouples, RTDs).
3. Dual Redundant IONet Communication: Equipped with dual Gigabit Ethernet ports for redundant network connectivity, ensuring uninterrupted data exchange with the Mark VIe controller and eliminating single points of failure.
4. Isolated I/O Channels: Each input and output channel features galvanic isolation, preventing electrical noise and cross-channel interference from disrupting signal integrity.
5. Real-Time Processing & High Precision: Powered by a 667 MHz PowerPC processor and QNX OS, delivering deterministic 5 ms scan times and ±0.1% FS accuracy for critical process control.
6. Robust Industrial Durability: Designed for harsh environments with wide temperature tolerance (-40°C to +70°C), conformal coating, and vibration-resistant construction.
7. Comprehensive Diagnostics & Protection: Onboard diagnostics monitor channel status, signal faults, and network health; outputs feature short-circuit detection and auto-recovery; front-panel LEDs indicate run, fail, and communication status.
8. Seamless Terminal Board Integration: Works with IS200TBAIH1C/STAIH1A/STAIH2A terminal boards for simplified field wiring, signal conditioning, and surge protection.
