1. Product Description
The IS220PRTDH1B acts as a bridge within GE’s Mark VIe architecture, managing communication between I/O networks and RTD terminal boards. It supports up to 8 RTD inputs with 3-wire configuration, enabling direct connection to platinum (Pt100/Pt1000) or nickel (Ni1000) sensors. Key features include:
- Dual Ethernet Connectivity: Two 10/100 Mbps ports for seamless integration with plant-wide networks, ensuring redundancy and fault tolerance.
- High-Accuracy Measurement: A 24-bit A/D converter with ±0.1% full-scale accuracy (typical) and resolution up to 0.01°C, ideal for applications requiring precise temperature monitoring 124.
- Dynamic Signal Processing: Advanced filtering algorithms reduce noise interference, while fast scan rates (up to 25 samples/second) enable real-time temperature tracking 1.
- Auto-Reconfiguration: Automatically adjusts settings when replaced, minimizing downtime during maintenance.
- Extreme Environment Compatibility: Conformal coating and extended temperature range (-30°C to 65°C) make it suitable for corrosive or high-vibration environments 124.
