I have been an electronics engineer for 25 years. I can answer questions on analog and digital circuits and my specialty is sensors.
I am the inventor on 23 US patents, and also some foreign ones. Developed sensors for over 25 years. Licensed private pilot (airplane and rotorcraft), have HAM radio license. I'm not an expert in computer networking.
I would like to pass on some information to help others.

There are several modules on the market for converting a 4 to 20 mA input signal to digital data output on a USB port. One is: http://www.robertoweninc.com/products/hardware/conversion/usb/a-d/current/roi-us
a. with the power supply only rated at 0.1A, the lamp will not light as brightly, or may not light at all because the power supply is not rated to supply enough current. b. with a power supply rated
FSK is in the range of about 1 to 3 kHz, or so. The FSK signal is impressed onto the AC power, and is only in the millivolt range, whereas the 50/60Hz power is 115, or 230, or 250 VAC, etc. If an appliance
A dry contact is a set of two connections that can be open or closed (connected together). A wet contact is the same set of contacts, but one of the contacts is already connected to a voltage. So, if
You would probably use the alternator (and a voltage regulator) to charge a 12V battery. If you want to operate 120VAC equipment, then you will need an inverter. An alternator & voltage regulator & battery
