Description
Product Description
The Honeywell DC-PDIL51 (51454818-175) is a precision Pulse Duration Input Module engineered for Experion PKS C300 controllers. It accurately captures high-speed digital pulse signals, making it ideal for applications such as turbine flow meters, tachometers, and other time-based process measurements. Each input channel is isolated to ensure reliable performance in electrically noisy environments, and the module supports redundancy for critical process control.
