Universal inputs (UIs) are designed to connect additional equipment with impulse, voltage, analog, or frequency outputs and monitor its operations.

Open the “Settings” menu and select the 'Inputs' tab; then go to 'Universal Inputs':

“Universal input”, select “On”.

“Operation mode”, select “Potential”.

“Transmit 1-Wire Sensor Values Instead of UI Values”, check this box if you need to transmit data from additional equipment connected via the 1-Wire interface.

“Potential input switching-on voltage threshold”, select the voltage threshold value that must be reached by the Terminal to record the sensor as “On”. The default value is 9 V.

“Pullup”, select “On”, if you're working with “open collector” or contact type sensors.

“Invert Input Signal”, select “On” for sensors with open contacts or contacts that lock as a result of a specific action or event.

“Current Voltage”, displays the Terminal's universal input voltage value.

“Current Value”, displays if the additional equipment is on or off.

“Send SMS upon triggering”, select “On”, if you want the Terminal to send SMS text messages when a voltage universal input is activated.

“Equipment name”, enter a parameter controlled.

Potential types of sensors: contact or non-contact discrete sensors.

Connect contactless sensors (capacity, induction, optical or magnetic) and N-P-N type sensors with 'open collector' output according to the figure below:

Connect contact sensors according to the figure below:

You can use standard factory equipment elements (such as on/off buttons, end switches/sensors that are activated by changes in temperature or pressure values, etc.) as contact sensors, or any additionally installed sensors. We recommend to first examine your options of connecting to a standard device or element, and only installing an additional sensor in case that this is not possible.

Sensors with analogue output:

Measured Variable Minimum Value, set the minimum value for the variable measured by the sensor, defined in appropriate units. Voltage Associated With Minimum Value, set the voltage value that should be associated with the minimum value of the measured variable. Measured Variable Maximum Value, set the maximum value for the variable measured by the sensor, defined in appropriate units.

Voltage Associated With Maximum Value, set the voltage value that should be associated with the maximum value of the measured variable.

Current Universal Input Voltage, displays voltage value at Terminal's universal input.

Current Universal Input Value, displays current value of the measured variable.

Equipment Name, enter the name of the monitored parameter.

Types of analogue sensors:

Standardised current output

Standardised voltage output

Sensors with frequency output

Universal Input, select “On”.

Operation Mode, select “Frequency”.

“Transmit 1-Wire Sensor Values Instead of UI Values”, check this box if you need to transmit data from additional equipment connected via the 1-Wire interface. This will prevent data transmission from the universal input.

“Pull-up”, select “On” if you're working with “open collector” or contact type sensors.

Current Universal Input Value, displays the current value of the measured variable.
