Timer/Controller for Industrial Filtration Systems

Product Specifications

Technical details and manufacturing context for Timer/Controller

Definition

A Timer/Controller is a critical component within industrial cleaning mechanisms such as shakers and pulse jet valves used in dust collection systems. It precisely controls the timing, duration, and frequency of cleaning cycles to maintain optimal filter performance and system efficiency by removing accumulated particulate matter from filter media. The device is typically housed in a plastic enclosure with metal contacts and electronic components, including a printed circuit board and integrated circuits. It operates by sending electrical signals at predetermined intervals to activate cleaning mechanisms. In shaker systems, it triggers mechanical vibration to dislodge dust from filters. In pulse jet systems, it controls solenoid valves to release compressed air bursts that clean filter bags. Modern controllers may use programmable logic to adjust cleaning parameters based on differential pressure or time intervals. Key specifications include a supply voltage of 24 V AC/DC ±10% (per IEC 61131-2), power consumption of 5–15 W, and a timing range of 0.1–999 seconds with accuracy ±0.05% at 25 °C. The number of programs is selectable via front panel (10–20), and the number of outputs ranges from 4 to 16, each independently programmable. Output rating is 250 V AC, 5 A resistive load (derate for inductive loads, per IEC 60947-5-1). Operating and storage temperature range is -40 to 85 °C (non-condensing), relative humidity 5–95% (non-condensing, per IEC 60068-2-78). Ingress protection is IP54–IP65 (per IEC 60529), enclosure material is ABS (flame retardant grade, UL 94 HB), and weight varies from 0.5 to 1.5 kg depending on the number of outputs. These values are reference ranges; verify model-specific specifications with the manufacturer or supplier before procurement.

Working Principle

The Timer/Controller operates by sending electrical signals at predetermined intervals to activate cleaning mechanisms. In shaker systems, it triggers mechanical vibration to dislodge dust from filters. In pulse jet systems, it controls solenoid valves to release compressed air bursts that clean filter bags. Modern controllers may use programmable logic to adjust cleaning parameters based on differential pressure or time intervals.
