Seeking advice on outdoor dashboards
Thread Content
There is a small tank area that needs to be equipped with automatic control systems; it includes several remote-mounted level gauges and several shut-off valves, as well as alarm and interlock shutdown functions. Since it is not planned to set up a control room, it is desired to install local control panels that can be used outdoors right next to the tank area. How should this be done? Seeking guidance
Without a control room, how can it be controlled? ?
It is feasible to do this: use cabinets with a high IP rating, and inside them install PLCs that do not require an upper-level controller (models capable of withstanding harsh environments), along with control buttons and indicator lights. If it is inconvenient to set up the PLC, a relay circuit control can be used as an alternative.
Is there a SCADA system? If available, an RTU system can be installed; the signals from the tank area are sent to the RTU, which then transmits them via serial signals to the SCADA system.
Buy a small PLC; Siemens’ 300 series will be sufficient. A proper field control cabinet as well
How about making the on-site control cabinet into a waterproof box and adding a small rain cover?
Pay attention to the explosion-proof requirements and the protection rating. That’s all that matters
Sure. It’s sufficient to use a set of PLCs nearby; modern PLCs also come with AI modules, so it’s not difficult. Just find a manufacturer of PLCs, and everything will be resolved.
