Description
Emerson 1C31189G03 Speed Detector Module
The Emerson 1C31189G03 is a high-precision speed detection module designed for industrial automation systems, particularly within Emerson’s Ovation Distributed Control System (DCS). Engineered to deliver reliable performance in harsh environments, this module enables real-time monitoring and control of rotational speeds in critical applications such as power generation, water treatment, and manufacturing. With its advanced features and robust design, the 1C31189G03 ensures optimal equipment performance, reduces downtime, and enhances operational efficiency.
The
Emerson 1C31189G03 serves as a vital component in industrial control systems, providing accurate speed measurements for machinery such as turbines, pumps, and conveyors. It interfaces seamlessly with magnetic or optical speed sensors, converting raw signals into actionable data for process control. The module’s compact form factor (180 mm × 50 mm × 120 mm) and DIN rail/panel mount compatibility make it suitable for space-constrained environments. Its
±0.05% full-scale accuracy and
0–10 kHz input frequency range ensure precise speed monitoring, while
24 VDC power consumption and low-power design minimize energy costs. The
1C31189G03 also integrates diagnostic LEDs for real-time status monitoring and fault detection, enhancing system reliability.
