Convertisseur électro-pneumatique IPC6 et IPC6 ATEX
L'EP6 est un positionneur alimenté par boucle à 2 fils nécessitant un signal de commande de 4-20 mA et est conçu pour être utilisé avec des actionneurs pneumatiques linéaires et rotatifs. Le positionneur compare le signal électrique d'un contrôleur avec la position réelle de la vanne et fait varier un signal de sortie pneumatique vers l'actionneur en conséquence. Le kit de montage convient à tous les actionneurs pneumatiques conformes à la norme NAMUR.
