Introduction of DMK-4CSA-20 Controller

1. Overview

The DMK-4CSA-20 is a pulse injection controller, which serves as the main control device for the pulse injection cleaning system of the pulse bag dust collector. It controls the electromagnetic pulse valves by outputting signals, enabling the compressed air to cyclically inject and clean the filter bags. This maintains the resistance of the dust collector within the set range, ensuring the dust collector’s processing capacity and dust removal efficiency.

2. Functional Features

Flexible Control Modes: It adopts a programmable combined output mode, capable of achieving one-machine control for small-scale dust collectors with less than 19 output points. It can be combined into a mode of M lift valves + N pulse valves, easily realizing M + MN point switch quantity output. It can achieve both online and offline control. When M = 0, it is in the offline cleaning mode.
Superior Output Performance: Using imported high-power contactless devices for output, it can achieve real-time output of the pulse valves, improving the hysteresis phenomenon of relay output.
Diverse Parameter Settings: The core control uses a single-chip microcomputer, allowing the setting of key parameters, including digital display, cycle interval, pulse interval, and pulse width, etc. And it controls the cleaning process according to the “Stop/Run” signal. The output pulse width can be adjusted within the range of 0.01 – 0.99 seconds. The adjustment range of the output pulse interval is 1 – 99 seconds, and the adjustable range of the cycle interval is 0 – 99 minutes.
