Isolated Input component

A set of 2 isolated inputs that can take a high voltage or floating input and convert to a standard digital input via the use of opto isolators. A high is received when the voltage across the terminals is low 0 - 4V. A low is received when the voltage across the terminals is high 6 - 48V.

Version information

Library Version, Component Version, Date, Author, Info
8, 8.0, 02-04-25, MW, ESP32 compile fail. Added .Retun to ReadState function
9, 8.0, 08-05-25, BR, Added autodetect port on Ev_PostInitialise

Macro reference

ReadAll

	ReadAll
Reads all of the inputs at once, returning a byte containing one bit per input. Range 0-3.
- BYTE	Return

ReadState

	ReadState
Read the state of the input at the given index. 0 = Voltage Present on input, 1 = No Voltage Present on input
- BYTE	Index
The input to read the status of. 0 or 1
- BOOL	Return

WaitUntilHigh

	WaitUntilHigh
Pause the program until the input at the given index is turned on.
- BYTE	Index
Index of the switch to wait for.
- VOID	Return

WaitUntilLow

	WaitUntilLow
Pause the program until the input at the given index is turned off.
- BYTE	Index
Index of the switch to wait for.
- VOID	Return

Property reference

	Properties
	Connections
	Input Mode
Choose how your switches are connected. PORT = Single port byte for all switches - pins are allocated in sequence from pin 0 - X Custom = Individual pin by pin connections
