== Input protection ==
As compared to previous versions, input protection and general noise immunity are significantly improved.
#All inputs are protected from applying the power supply voltage (up to 24 V) and transient noise.
#Wiren Board 4 is protected against reverse polarity.
#Wiren Board 4 features one optically isolated RS-485 interfaces.
#Low-side FET switches on Ax and Dx inputs are protected from negative voltage spikes from inductive loads.
# Relays have sparking suppression circuits

== Multifunctional inputs/outputs Ax and Dx ==
 
[[File:Ax.png|thumb|400px| Equivalent circuit of A1-A3 channels]]
[[File:А5.png|thumb|400px|Equivalent circuit of A4-A5 channels]]
[[File:Dx.png|thumb|400px|Equivalent circuit of Dx channels]]


As compared to version 3, input protection and general noise protection are significantly improved.
Multifunctional channels consist of input and output stages are connected in parallel, as well as protective diodes (connected to one terminal of the channel).
#Protection of all inputs from power supply voltage (up to 24 V) and pulse noise.
#Protection from reverse polarity.
#One optic isolated RS-485 port.
#Diode protection of keys at Ax and Dx inputs from inductive loads.
#Protection from relay contact sparking.


Output stage consists of the Tx switch.
The Tx switch can connect the corresponding output with ground.


The state of the switch is controlled by logic circuits inside the controller.  The switch may be one of 2 states:


*Active (closed); channel output is connected to ground (0V)


== Versatile inputs/outputs Ax and Dx ==
*Inactive (open), high impedance.
Such outputs are called “open collectors”.


[[File:Ax.png|thumb|400px| Equivalent channels A1-A3 scheme]]
Input stage of Ax channel consists of an analogue-to-digital converter ADCx and an input resistor Rx.  
[[File:А5.png|thumb|400px|Equivalent channels A4-A5 scheme]]
[[File:Dx.png|thumb|400px|Equivalent channels Dx scheme]]
Versatile channels consist of input and output stages that operate simultaneously, as well as protective diodes (connected to one terminal of the channel).


Output stage consists of the Tx switching element.
The ADC has a high impedance, so it doesn't affect the channel operation even if the channel works as output.
Tx key grounds the outputs.  
Under control of the controller logical boards, the Tx key may be one of 2 states:


*Active (closed); 0 is at the channel output.


*Inactive (open), high impedance. Such outputs are called “open collectors”.
In input mode the Tx switch is inactive (open) and, thus, does not affect voltage measuring at the channel terminals. Input resistance of the channel in input mode is determined by the Rx resistance.  


Input stage of Ax channel consists of an analogue-to-digital converter ADCx and an input resistor Rx. Input resistance of the ADCx is high. It is always ON and does not affect the channel operation as it works in output mode. In input mode the Tx key is inactive (open) and, thus, does not affect voltage measuring at the channel terminals. Input resistance of the channel in input mode is formed by the Rx resistor. If no other circuits are connected to the channel terminals, the resistor downs the input voltage to zero, and the ADCx converter will read 0.
If the channel terminal is left floating, the input voltage measured by ADCs is pulled down to zero by the Rx resistance.


А4 and А5 support binary input function DI: more than 3V at the terminal is considered as triggering of the input.

Allowed voltage range is 7-24 V.  
Allowed voltage range is 7-24 V.  
Average power consumption of the board is 1.5-2 W, but the GSM module may temporally consume as much as 8 W. Therefore, it is recommended to use at least 10 W power sources.
