8C-PAIH51 Honeywell Analog Input HART 16 Ch | In Stock

Honeywell 8C-PAIH51 Analog Input with HART

Key Features and Capabilities

• Input Type: 4-20mA current (2-wire or self-powered transmitters).
• Input Channels: 16 single-ended channels for dense I/O density.
• A/D Converter: 16-bit resolution for precise measurement.
• HART Support: Enables multivariable instrument communication and fast control variable collection.
• Fast Loop Scan: 50 ms scan rate for time-critical processes.
• Optional Redundancy: Provides fault tolerance for high-availability systems.

Non-Incendive Power and Protection

• Non-Incendive Power: No external marshalling required – module supplies field power.
• Channel Protection: Individually protected current limiting circuits for Class 1, Div 2 hazardous areas.
• No Fusing Needed: Built-in protection eliminates external fuse requirements.
• Maximum Input Voltage: ±30 Volts (any input referenced to common) – no damage.
• Input Range: 4-20 mA through 200 Ω resistor.

Accuracy and Noise Rejection

• Hardware Accuracy (@ CMV = 0 V): ±0.075% of full-scale at 23.5°±2°C.
• Hardware Accuracy (0 to 60°C): ±0.15% of full-scale for industrial environments.
• Normal Mode Rejection Ratio (60 Hz): 19 dB for line frequency noise rejection.
• Normal Mode Filter Response: Single-pole RC, -3 dB @ 6.5 Hz.
• Crosstalk (dc to 60 Hz): -60 dB channel-to-channel for signal integrity.
