2.2 LED Indicators
The device is equipped with LEDs for quick status checking and diagnostics:
Figure 3. LEDs on the front panel of iSMA-B-MAC36NL.
1. The Universal Inputs LEDs U1-U16 indicate the statuses of the Universal Inputs. When the
LED is ON, the resistance value connected to the input is lower than the switching
threshold value (Dry Contact input is active).
Note: The LED also lights up when the voltage connected to the input has very low potential.
2. The Digital Inputs LEDs I1-I4 indicate the statuses of the Digital Inputs. When the LED is
ON, the Input is active (resistance value connected to the input is lower than the switching
threshold value).
3. The Analog Outputs LEDs A1-A8 indicate the statuses of the Analog Outputs. When the
LED is ON the Output voltage or PWM factor is different than 0.
4. The Digital Outputs LEDs O1-O8 indicate the statuses of the Digital Outputs. When the LED
is ON the Outputs is active (closed circuit).
2.3 Universal Inputs (16x UI)
All the Universal Inputs have 16-bit ADC, which support the following types of the input signals:
•Voltage Input (0 – 10 V DC)
•Current Input (0 – 20 mA)
•Resistive Input (0-1000 kΩ)
•Temperature Input
•Dry Contact Input (Digital Input)

2.3.1 Voltage Input Connection (0 –10 V DC)
Figure 4. Connection of UI to measure voltage 0-10 V DC.
2.3.2 Current Input Connection (0 –20 mA)
Current measurement is realized by voltage measurement and 200 Ω resistance.
According to Ohm’s law, the current is directly proportional to the voltage and the resistance
is the constant of proportionality.
𝑰 = 𝑼
𝑹
According to the Ohm’s law equation, for 20 mA current with 200 Ω resistance the output
voltage is 4 V.
It means that the 4 V voltage measured on the Universal Input corresponds to 20 mA current.
The result is expressed in millivolts.

the characteristics.
Figure 20. Universal Input: Input Type - Custom Table
After selecting from the Custom Table drop-down list, an additional Custom Table slot is
displayed. This slot has ‘Resistance’ and ‘Out value’ subslots for the next points of the
characteristics. When both subslots are filled in and approved with the Enter key, the next
subslots open in the next row. It is possible to enter up to 32 points of characteristics (32 rows
of Point 0...31). The characteristics are saved in the component in the station. If the user
changes the input mode, the characteristic will be saved and you can return to it by selecting
Custom Table again. To delete the entered characteristic, right-click on the Custom Table slot
and select Delete. A UI component with a saved characteristic can be copied and used

repeatedly without having to re-enter it. The UI component can also be copied between
stations, both online and offline (PC copy). You can also copy the Custom Table slot itself and
paste it into a new UI component under ProxyExt (where there is no Custom Table yet). There
can only be one Custom Table slot in the UI component.
