Product Description

The SAI143-H63 is a 16-channel analog input module that receives 4 to 20 mA signals from field transmitters. This specific “H63” variant supports HART communication, allowing for the transmission of digital device variables and diagnostic information alongside the analog signal. It is a module often used in safety-related applications, providing a bridge between field sensors and the controller logic.

Product Parameters

• Channels: 16 channels, isolated.

• Input Signal: 4 to 20 mA DC.

• Input Impedance: Approximately 250 Ω.

• Accuracy: ±0.1% of full scale.

• Data Refresh Cycle: 10 ms (depending on the system configuration).

• HART Communication: Supported (HART 5, 6, and 7).

• Withstanding Voltage: 1500 V AC between input terminals and system ground.

• Power Consumption: Max 320 mA at 5 V DC; Max 230 mA at 24 V DC.

• Installation: Compatible with Yokogawa FIO (Field network I/O) nodes.

Product Advantages

• HART Protocol Integration: Enables remote configuration, monitoring, and diagnostics of field devices without additional wiring.

• High Reliability: Designed for mission-critical applications with robust electrical isolation between channels and the system.

• Hot-Swappable: Supports online replacement (hot-plugging) to minimize system downtime during maintenance.

• Compact Footprint: High density (16 channels) allows for significant space savings within the I/O cabinet.

• Precision: High-resolution A/D conversion ensures accurate process data for fine-tuned control loops.

Precautions for Use

• Terminal Matching: Ensure the correct pressure-clamp or screw terminal block is used to prevent loose connections or signal loss.

• External Power: When using 2-wire transmitters, verify that the 24 V DC loop power supply is stable and correctly fused.

• Noise Mitigation: Keep signal cables away from high-voltage power lines to prevent electromagnetic interference (EMI) from affecting the 4 to 20 mA signal.

• Safety Compliance: If used in a ProSafe-RS environment, ensure the module configuration complies with the required Safety Integrity Level (SIL).

Product Applications

The SAI143-H63 is widely utilized in heavy industries where process stability and safety are paramount:

• Oil & Gas: Monitoring pressure and flow transmitters on offshore platforms and refineries.

• Chemical Processing: Precise temperature and level monitoring in reactor vessels.

• Power Generation: Collecting data from steam and water loop sensors for turbine control.

• Water Treatment: Integrating flow meters and analytical sensors (pH/Conductivity) into the central control system.

• Safety Instrumented Systems (SIS): Serving as the input layer for emergency shutdown (ESD) and fire and gas (F&G) systems.
