== 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 | |||

[[File:А5.png|thumb|400px|Equivalent circuit of A4-A5 channels]] | |||
[[File:Dx.png|thumb|400px|Equivalent circuit of Dx channels]] | |||
Multifunctional channels consist of input and output stages are connected in parallel, as well as protective diodes (connected to one terminal of the channel). | |||
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) | |||
*Inactive (open), high impedance. | |||
Such outputs are called “open collectors”. | |||
Input stage of Ax channel consists of an analogue-to-digital converter ADCx and an input resistor Rx. | |||
The ADC has a high impedance, so it doesn't affect the channel operation even if the channel works as output. | |||
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. | |||
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. | А4 and А5 support binary input function DI: more than 3V at the terminal is considered as triggering of the input. | ||

These devices from output signals by closing two wires they are connected to. | |||
Connect one wire to the GND terminal or a common grounding bus. | |||
Connect the other wire to the Dx terminal. | |||
Some counters are equipped with an optron based pulse output. | |||
In such cases it is necessary to take polarity of the wires into account. | |||
The negative wire must be connected to GND, while the positive one must be connected to Dx. | |||
=== | === “Open collector” output devices === | ||
Both device and controller must be connected to the common grounding bus. Connect the "open collector" output to the Dx terminal. | |||
