Honeywell CC-PAIL51 Analog Input Module | 16-Channel TC/RTD

Precision input: CC-PAIL51

The Honeywell CC-PAIL51 is a Low Level Analog Output module. It reads thermocouples and RTDs with high accuracy. Part of the I/O family, it connects to CC-TAIL51 9″ IOTA. Each channel is fully isolated. This module works in extreme temperatures. Ideal for critical process control.

Model structure explained

• CC – Series: Honeywell Control Core
  • PAIL – Function: Low Level Analog Input
    • 51 – Type: 16-point module, works with CC-TAIL51 IOTA

Technical highlights

• Input type: Thermocouple or RTD – configurable per channel.
• Isolation: Full channel-to-channel and channel-to-power isolation.
• Scan rate: 1 second per channel – steady and reliable.
• Bandwidth: 0 to 4.7 Hz (-3 dB) – filters noise well.
• TC range: -20 to +100 millivolts nominal input.
• RTD excitation: 1 milliamp current source.
• Gain error: Only 0.050% full scale maximum.
• Temp stability: ±20 ppm/°C max for TC and RTD.
• CMRR: 120 dB min at 50/60 Hz – rejects interference.
• Open detect: 1000 Ω no-trip, 1500 Ω guaranteed trip.

Operating conditions

• Operating temp: -40°C to +70°C – tough industrial use.
• Storage temp: -40°C to +85°C – survives harsh storage.
• CMV tolerance: ±250 VDC or VAC RMS – strong protection.
• Line frequency: Fixed 50 Hz or 60 Hz selection.

Five professional FAQs

• Q1: What IOTA base does this module need?A1: It mates with CC-TAIL51 9-inch IOTA. The IOTA provides backplane connections and power distribution.
• Q2: Can I mix TC and RTD types on one module?A2: Yes, each of the 16 channels is configurable independently. You can mix thermocouples and RTDs freely.
• Q3: How does cold junction compensation work?A3: Built-in CJC measures terminal temp from -20°C to +60°C. Accuracy is ±0.5°C typical. No extra parts needed.
• Q4: What is the maximum RTD lead resistance allowed?A4: Maximum lead resistance is 15 Ω per lead. Higher resistance may affect accuracy. Use appropriate wire gauge.
• Q5: How fast do you ship this module?A5: We ship same day via FedEx, UPS, or DHL. Express delivery takes 2-4 business days. Tracking provided.
