Document Revision 4.2 Hardware Compatibility: 9240SI-S (Standard), 9240SI-P (Profibus), 9240SI-E (Ethernet/IP) 1. Introduction The 9240SI Loop Controller is a high-performance, single-loop, microprocessor-based digital controller designed for precision regulation of industrial processes including temperature, pressure, flow, and level. Unlike basic ON/OFF thermostats, the 9240SI utilizes advanced PID (Proportional-Integral-Derivative) algorithms with adaptive feed-forward control, making it suitable for non-linear and time-variant processes.
