Product Details
The Foxboro P0915KN, also cataloged as the P0915KN 8-Channel Analog Input Module, operates as a dedicated hardware component for analog signal processing and high-accuracy data acquisition within Foxboro I/A Series DCS networks. It converts incoming field signals across 8 independent channels into digitized variables for system controller execution.

Channel-to-Channel Isolation and Loop Integrity
The Foxboro P0915KN features internal signal conditioning circuitry designed to provide robust channel-to-channel isolation and suppression of high-frequency noise. Capable of processing 4-20 mA HART loop protocol transmitters, +-10 V signals, and J-type thermocouples, the module utilizes a high input impedance (>200 kOhm) and common mode rejection ratio (>60 dB) to prevent ground loops from corrupting real-time process control variables.
Frequently Asked Questions
Q: Does the P0915KN module require re-calibration when switching signal types between 4-20 mA and J-type thermocouples?
A: Signal ranges are configured via system software and onboard hardware jumpers without requiring physical component re-calibration.
Q: What are the backplane power supply draw limits for a single P0915KN input card?
A: The P0915KN operates with a total power consumption of less than 2 W drawn directly from the baseplate power rail.
Field Installation Guidelines
Ensure baseplate power is turned off before inserting or removing the P0915KN module. Align the card edge connectors with the mounting slot guide rails and push firmly until the locking mechanisms fully snap in place.
Run thermocouple and analog instrument wiring through dedicated low-voltage wireways, maintaining physical separation from AC power lines. Connect all signal cable shields to the cabinet ground bar at a single point. Ensure all NPT conduit connections maintain 5 full threads of engagement to meet industrial enclosure enclosure standards.
