DISN 800C/801C/801M FOR MEDIUM-SIZED INDUSTRIAL ENGINES

The DISN is a full-featured industrial ignition system for small- to medium-sized stationary engines up to 16 cylinders. The DISN system is intended for compression-stroke firing and usually uses a single pickup sensing, precision-machined timing disc rotating at engine camshaft speed. If crankshaft-referenced timing is desired, two pickups are used: one sensing firing magnets placed in the engine flywheel and the second sensing a single index magnet rotating at camshaft speed. Three basic series are available: 800C, 801C and 801M. All offer up to eight firing patterns in a common unit and are available in 8, 12 or 16-output models, each with multiple applications. The DISN systems also incorporate four advanced timing control options: manual 16-position timing switch, onestep timing change, remote potentiometer timing control or control from a 4- 20 milliamp analog signal. Three LED diagnostic indicators give an instant indication of the basic incoming power and pickup signals. The new cast housing offers superior protection in harsh environments. The DISN 801C series offers offset timing programmed in selected cylinders (for use with detonation detection systems) and two levels of spark energy. The 801M version is aimed at smaller engines with 4-12 cylinders and uses more economical connectors, pickups and triggering components.
