Honeywell 8C-PAIMAI Series 8 Analog Input Module

The Honeywell 8C-PAIMAI, also cataloged as the 8C-PAIMAI Analog Input Module, operates as a dedicated hardware component for multi-signal data acquisition and field instrumentation monitoring within Honeywell Series 8 automation platforms.

Hardware Specifications

Channel-to-Channel Isolation & Process Control Integration

The 8C-PAIMAI module processes 8 differential analog channels, supporting configurable 4-20 mA DC, 0-20 mA DC, 0-10 V DC, and ±10 V DC input ranges. Designed for integration with Honeywell Series 8 controllers, the hardware features channel-to-channel galvanic isolation rated at 250 V AC rms and power-to-signal isolation rated at 500 V AC rms to prevent ground loop currents and common-mode noise corruption in continuous process control loops.

Frequently Asked Questions

Q: What are the primary isolation ratings between channels on the 8C-PAIMAI?

A: Channel-to-channel isolation is rated at 250 V AC rms, while power-to-signal isolation is specified at 500 V AC rms.

Q: What is the step response time for an analog input channel on the 8C-PAIMAI?

A: The module achieves a step response time of <= 100 ms for a 90% full-scale signal change.

Q: What field signal types can be wired directly to the 8C-PAIMAI module?

A: The module accepts 4-20 mA DC, 0-20 mA DC, 0-10 V DC, and ±10 V DC differential analog signals.

Field Installation Guidelines

• IOTA Chassis Engagement: Insert the 8C-PAIMAI module into its designated Series 8 IOTA slot until the backplane connectors seat completely, securing retaining latches to ensure structural stability.
• Shield Cable Termination: Connect overall and individual pair cable shields directly to the chassis earthing bar to maintain high-frequency noise rejection across differential input pairs.
• Wiring Separation: Route low-voltage analog signal cables in independent wireways separated from high-power AC distribution lines and switching inductive loads.
