Honeywell 51309355-001 DR4500 Truline Processor Board

Product Description

The 51309355-001 is a high-performance industrial processor board engineered specifically for the Honeywell DR4500 Truline Circular Chart Recorder series and compatible TDC 3000 systems. As the primary computational engine of the recorder, this board manages high-speed data acquisition, real-time chart tracing, and digital PID control execution. It is designed to handle complex signal conditioning for various industrial inputs, ensuring that critical process variables are recorded with scientific precision.

The 51309355-001 supports up to four independent process variables, allowing for simultaneous monitoring of thermocouples, RTDs, and standard current loops (4–20mA). Its robust architecture enables the execution of one to two internal control loops, providing integrated automated regulation without the need for external controllers. Built to withstand the thermal and electrical noise of heavy industrial environments, this processor board ensures deterministic performance and long-term data integrity for compliant record-keeping and process analysis.
