We are starting a New development for an Oil & Gas Valve Automation Field Application that requires battery independence for 5+ years in the field.
On it's first version, this is a small system that will monitor 12 Digital input signals and control 12 outputs: 10 indicating LED's and 2 solenoid valves (12v). We would like the Product to have a Real Time Clock to time-log the input signals events and also have Bluetooth Low Energy communication capabilities for occasional connection by the Operators when visiting the site to monitor Battery Status, update configuration (name, clock, Valve Tag, etc) and download any available Log information, as well as being able to force an output, for example.
Regarding power, we are considering a "Battery Pack" with 5 to 10 of 3.6v, 2.4A-H Li-Ion Batteries (AA-Size, EaglePicher PT-2100 or similar) could be the power source for the Product. (Split in two voltages: 3.6x4=14.4v for the solenoid and the rest to power the Product at 3.6V)
It is very important that the Product monitors the "Battery Pack" Status and if this goes below a threshold in either of the voltage buses, an action is taken with one of the solenoids (valve closing) to set the Product in a LOW BATTERY Mode at a Safe Process State.
We would like the product to comply with Functional Safety requirements if possible.
This is a small Block diagram of this product concept.
Could you please help us with your recommendation for the best fitted TI product(s) for such application?
Thanks in advance for your support.
Best Regards,
Arturo Trevino
