Product Description
The Foxboro P0916KH is an 8-channel input module designed for the I/A Series Distributed Control System (DCS). It provides reliable interface capabilities between field devices and the Foxboro system, enabling precise monitoring of both discrete and analog signals. Moreover, this module ensures secure communication with the system bus while maintaining electrical isolation for each channel.
Engineered for robust industrial environments, the P0916KH supports thermocouple and millivolt input signals with high-resolution acquisition. Its built-in cold junction compensation improves accuracy for thermocouple measurements, making it suitable for critical process monitoring. In addition, the module is compatible with both DIN rail and rack-mounted configurations, providing flexible integration in existing control architectures.
