I looked in specs for WST8035 and see that maximum allowable feed is 12VDC.
However, when looking in schematics, I can see the input voltage going via C8 and C4, into UA7805
According to the datasheet of UA7805, its safe to feed it up to 25 V.
This means, that if I replace C8 and C4 with capacitors with the same value, but higher voltage rating, I should be able to put in 24VDC into it right?
Or if I just scrap the UA7805, C8, C4, C9 and C5, and just connect a LM2596S based regulator set for 5V output right on the output line right?
You might wonder why I ask all this, its because I have a people counter, a Brickstream 2300M-BC25W, which requires a feed of 24VDC.
and I would want to avoid down-regulating 2 times, and want to feed it off the same power supply. Would be easier to install if I just need to run network cable to the brickstream, and 24VDC to both, and then 2-wire output line to the alarm system. (2 wire output will be the EQUAL OUT and GND connected to a sensor input on the alarm panel, with the EQUAL OUT set to 0 0 0 0, so when building is empty, the system will get a “okay to arm” signal)
(The counter and brickstream are supposed to make so the alarm system can automatically arm itself when everyone has left the building, and disarm automatically when someone scans the access tag in the front door to enter the building, so nobody needs to touch the alarm panel)
