These ¼ DIN dual display instruments feature individual control loops which can be set for control action (fully programmable PID or on/off), monitor and alarm functions (incl. heater and sensor break alarms) via the instrument keypad and have a wide range of sensor inputs to choose from. Outputs can be selected form SSR, Relay or current output.

The MA900/901 controllers utilise continuous self tuning which, in the majority of applications, sets the controller up for optimum performance. A Heat/Cool version is also available for applications where the process generates heat (the use of heat/cool PID contributes to stable control and energy savings).
