Series A6

The Series A6 is a microprocessor based controller for positive, negative, and differential pressure as well as velocity and flow. The Series A6 has a 316L Stainless Steel cover to meet clean room and other high purity and wash down requirements. It features (2) 8A SPDT relays for control and an optional digitally scaleable 4-20 mA output. The associated programming menu allows full configuration of variables such as setpoints, dead band, engineering units, flow coefficients, and more. The programming is done from a user friendly menu on the OLED display or uploaded using an Optioptilink Link™ programming key. The OLED also displays the exact setpoints or other user defined variables during normal operation. Furthermore, the menu structure can be customized by moving variables to different menu levels to accommodate many applications.
