Water plants usually have several filter beds that are controlled by a DCS, PLC or PID controller. However, there are times when manual control close the filter bed is needed by a plant operator.
When this need arises, look to the 532 ¼ DIN Auto/Manual Station. The Nema 4X UL approved 532 allows the control signal (CV) to pass through the controller to the final control element in the normal mode. When local control is required the operator simply presses the MANUAL button on the controller to take control of the 4-20mA signal that is driving the final control element. The 532 features a large vacuum fluorescent display with a large five digit upper display and two nine character lines of alphanumerics. Additionally, soft and hard alarms can be set to notify when the 532 has been put in local MANUAL mode.
- Easy to use push button auto/manual station
