• Gives position feedback from an actuator locally and remotely
• Gives operator a clear indication on valve position
• Enclosures offered in multiple area classifications, including explosion-proof, intrinsically safe, weatherproof types
• Wide variety of mechanical, proximity and inductive switch options provide the most effective and economical choice for each specific application
• AS-i digital communication interface card, 3-position dribble control, 4-20mA feedback transmitter, special terminal strips, NAMUR mounting brackets
