Yokogawa SAI143-H63 Analog input module Large inventory

The Yokogawa SAI143-H63 is a 16-channel analog input module used in Yokogawa’s ProSafe-RS safety instrumented system (SIS). It’s designed to convert 4-20 mA current signals from field devices into digital data for the SIS. Here’s a summary of its key features and specifications:

Key Features:

• 16 isolated input channels: Each channel can receive a separate 4-20 mA signal, providing high density signal acquisition.
• HART communication: Supports HART protocol for remote configuration and diagnostics of connected field devices.
• Module isolation: Each channel is electrically isolated from the others and the system backplane, minimizing the risk of ground loops and interference.
• Dual redundancy: Can be configured in a redundant pair for increased system reliability and fault tolerance.

Specifications:

• Input range: 4 to 20 mA
• Data update frequency: 40 ms
• Accuracy: ±0.1% of reading
• Resolution: 12 bits
• Power consumption: 10 W
• Dimensions: 30 x 90 x 100 mm
• Weight: 0.5 kg
