Description
Product Description
The Honeywell 51402797-200 is a 16-channel analog input module engineered for Honeywell Distributed Control Systems, including Experion PKS and legacy TDC platforms. It acquires and converts analog signals from field instruments such as temperature, pressure, and flow sensors into digital data for precise monitoring and control. With Modbus RTU communication, dual Ethernet/RS-485 connectivity, and rugged aluminum construction, this module provides reliable performance in industrial environments. It is optimized for integration, high signal fidelity, and efficient cabinet space usage.
