Specifications: 5V 1/2/4/6/8 Channel Relay Board Module Optocoupler LED for Arduino PiC ARM AVR
I purchased the above Optocoupled Relay Boards from Ebay: **broken link removed**
On arrival I Googled the components on PCB.
LM2596
3-A Step-Down Voltage Regulator
PHOTOTRANSISTOR/PHOTOCOUPLER...
The 9v supply powers the Reference voltage IC, and the dedicated 5v regulator for Arduino.
Operating the coils from 9v Battery should be fine, power consumption was not the consideration.

Re: 5V 1/2/4/6/8 Channel Relay Board Module Optocoupler LED for Arduino PiC ARM AVR
I am planing to use Arduino Micro running from 5v Regulator to operate the optocoupled relay, only one at a time!
I am using a 5v Reference IC for Arduino Aref.
The reference IC needs 8v minimum! (Using 9v)...
Not here, but hysteresis can be the problem and solution.
As in the Johnson Controls thermostat on the Cool Room.
Tuning off several degrees lower then on.
I read that hysteresis can be a problem with emitter follower, it could be switching off where I remember a problem circuit!
It seems...

Voltage control system for Charging Series Capacitors - Electronic Circuit Update
Recently reintroduced my self to Basic with purchase of Picaxe IC.
Everything I wanted and could not afford in the eighties, and a lot more.
I purchased a few of the 12 channel relays and other sizes to cover any module size requirements.
As a general switch, it would be advantageous to change...
Function After Capacitor is Charged:
The capacitor will be tapped into a cell in parallel.
During this time, any voltage it holds above the cell will transfer.
Before being disconnected from cell and charged back up to the 1/17th reference.
Repeat process for each cell.
For this Sequence of 17...
Thank you for the help.
There are a lot of people interested in the charging of Lifepo4 Cells, because they offer good value for capacity and come in large format.
Lifepo4 is in common use, but the flat charge and discharge curve makes standard balance methods unsuitable.
I wanted to build a...
The bare link shows information for using H Bridge that Klaus would like to use in his design.
The 1/17th voltage divider is connected across Solar Charger for 17 Lifepo4 Cells.
This follows changes in supply rail during charging, on any set charging voltage.
The 1/17th voltage is obtained...
Your using position of moderation to justify harassment.
I spend a lot of time on the detail to explain my ideas, and to help others.
I am the founder and admin of a forum.
No pay is required, I do it because I want to help people.
You seem to treat your ranking as some type of competition...
What is a MIMIC?
A mimic is one that mimics, often with out the time for detail.
This is a BMS I looked at some time back.
It is relatively simple to understand.
I am trying to do the exact opposite!

@Klaus, please do not respond! I will request you are blocked or I will leave the forum, get over it!
The opp amp data sheet is very confusing, can someone help with the characteristics for resistance values at inputs!
