نظام التحكم في الضغط من Kromschroeder TC318R05N (84765730)

The Krom schroder TC 318R05N 84765730 tightness control of two shut-off valves before burner start or after shutdown. Kromschroder TC 318R05N 84765730 tightness control technical data: Weight: 1, 51 kg F1: protection of valve outputs (terminals 15 and 16), fault signal (terminal 12) and supply of the control inputs (terminals 2,7 and 8). F2: protection of the safety interlock/controller enable signal (terminal 6). The input current at terminal 1 must not exceed 5 A. TC switching cycles: 250,000 pursuant to EN 13611. Reset: using a button on the device or by remote reset. Gas type: natural gas, town gas, LPG (gaseous), biogas (max.0.1%-by-vol. H2S) and air. The gas must be clean and dry in all temperature conditions and must not contain condensate. Measurement time tM: 5 to 30 s, adjustable. Set at the factory to 30 s. Medium and ambient temperatures: -20 to +60°C (-4 to +140°F). No condensation permitted. Long-term use in the upper ambient temperature range accelerates the ageing of the elastomer materials and reduces the service life. Storage temperature: -20 to +40°C (-4 to +104°F). installation altitude: 2000 m AMSL. 5 cable glands: M16 x 1.5. Cable cross-section: min. 0.75 mm2 (AWG 19), max.2.5mm2 (AWG14). Valve opening time: 3 s. Housing made of impact-resistant plastic. Connectors: aluminium. Enclosure: IP 65.
