5X00034G01 Emerson Compact Sequential Event Input Card

Caractéristiques fonctionnelles :

Enregistrement d'événements haute précision : La précision de l'horodatage peut atteindre 0,25 millisecondes (pour une carte), combinée avec un filtre d'élimination de bruit interne de 4 millisecondes. Se référant à l'heure de l'horloge du système, elle peut enregistrer précisément la séquence d'apparition des événements, ce qui est utile pour analyser précisément les causes des pannes de processus.

Entrée multi-canaux : Avec 16 canaux, chaque canal peut être configuré séparément pour les opérations d'entrée numérique (DI) ou d'entrée d'événement séquentiel (SOE), répondant à diverses exigences de surveillance.

Haute capacité anti-brouillage : Chaque canal est isolé optiquement du système. La valeur de test en usine est de 1500VDC, ce qui peut résister efficacement au bruit et aux interférences, garantissant l'exactitude et la stabilité de la transmission du signal.

La détection du signal est sensible : Le niveau de détection ? ON ? est > 2 mA, le niveau de détection ? OFF ? est <0.25mA, and the input impedance is approximately 5K ohm, which can accurately identify the on-off state of the signal.

Supports multiple devices: It can be connected to various digital field devices such as switches, encoders and sensors, serving as the interface between Emerson Ovation's distributed control system (DCS) and digital field devices to achieve data transmission and interaction.

On-board diagnostic function: It is equipped with on-board diagnostic function, which facilitates technicians to troubleshoot and maintain the system. It can promptly identify problems that occur during the operation of the module, reduce downtime, and enhance system reliability.

Wide operating temperature range: The operating temperature range is from -40 ℃ to + 70℃, capable of adapting to various harsh industrial environments and ensuring stable operation under different temperature conditions.

Shock and vibration resistance: Compliant with industrial shock and vibration standards, it can withstand a 10g? -sine wave shock lasting for 11ms, as well as a 1mm peaking value (from 2 to 13.2Hz) and 0.7g (from 13.2 to 150Hz) vibration. It can operate reliably even in harsh mechanical environments.

Compact and lightweight design: It adopts a compact design, weighing approximately 480g, which is convenient for installation in control cabinets and panels, saves space, and is easy to integrate into existing systems.

Application field

Power industry: It is used in relay protection devices of thermal power plants and substations to monitor key signals such as the opening and closing of circuit breakers and the operation of relays. Monitor events such as steam turbine tripping, generator excitation switch operation, and auxiliary machine start-up and shutdown.

Petrochemical industry: Monitoring signal inputs such as pressure switches and temperature sensors that trigger ESD in chemical plants; Monitor the operating status of the agitator in the reaction vessel, the signal of valve opening and closing in place, etc., to achieve sequential control of process steps.

Metallurgy and steel industry: Monitor signals such as the material level switch of blast furnaces, the clutch action of rolling mills, and the status of cooling water valves.

Municipal and public utilities: PLC System for Sewage Treatment plants

Application scenarios: Monitoring signals such as the start and stop of the aeration tank fan, the operating status of the grid machine, and the valve opening limit; Monitor the signals of platform screen door Ouverture et fermeture, signaux de déclenchement d'entrée de train, etc. sur la plateforme de métro.
