1.2 Overview
The iSMA-B-MAC36NL is a compact Master Application Controller with built-in different types
of I/O and operating in the Niagara Framework environment.

2Local IO Hardware Specification
The iSMA-B-MAC36NL has built-in different types of I/O. The specific local I/O set 16x UI,
8x AO, 4xDI and 8x DO allows using the device in different applications.
2.1 Terminals and Internal Connection Diagram
The iSMA-B-MAC36NL controller can be supplied by 24 V AC/DC. The power supply block is
separated. The grounding pin located next to power supply terminals must be connected to
the ground.
The device has 36x local I/O on board:
•8x Digital Outputs (8DO), relay output with max. load 3 A @ 230 V AC/30 V DC.
•8x Analog Outputs (8AO), voltage output 0-10 V DC maximum load up to 20 mA.
•16x Universal Inputs (16UI), temperature, voltage, current, resistive or dry contact.
•4x Digital Inputs (4DI), dry contact inputs or fast counter up to 100 Hz.

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.
Figure 5. Connection of UI to measure current 0-20 mA.

2.3.3 Temperature Input Connection
Temperature measurement based on resistance.
The Universal Inputs working as Temperature Inputs support the following types of sensors:
series NTC 10K3A1, 10K4A1, Carel 10K, 20K6A1, 2.2K3A1, 3K3A1, 30K6A1, SIE1, TAC1, SAT1
and Pt1000, Ni1000.

2.3.4 Dry Contact Input Connection (Digital Input)
Universal Inputs can operate as standard Digital Inputs (Dry Contact Inputs).
The Input is active when it is connected to the ground (G0).

2.4 Digital Inputs (4x DI)
In addition to the standard Dry Contact Input, Universal Inputs can operate as fast pulse
counters with up to 100 Hz impulse frequency counting.
The Input is active when it is connected to the ground (G0).
Figure 8. Connection to the Digital Input.
2.5 Analog Outputs (8x AO)
All the Analog Outputs have 12-bit ADC, provide 10 mV resolution and accuracy less than
±0,5%. They support the following types of output signals:
•Voltage Output (0 – 10 V DC) with max. load up to 20 mA
•PWM: 0,01 Hz, 0,1 Hz, 1 Hz, 10 Hz, 100 Hz

2.5.2 Relay to Analog Output Connection
There is an option to control the 12 V DC relay from the Analog Outputs (max. load cannot
exceed 20 mA!).
Figure 10. Relay connection to the Analog Output.
2.6 Digital Outputs (8x DO)
Relay Outputs (NO) have max. resistive load up to 3 A @ 230 V AC and 3 A @ 30 V DC.

3Local IO Driver
The Local IO Driver is dedicated to service, program and maintain local IOs.
The driver and Local IO points added under Local IO Network do not need a license –they are
free of charge and do not consume points from the license.
The driver contains the following components:
•iSMA IO Network
•Local IO Device
•Universal Input
•Digital Input
•Digital Input Counter
•Analog Output Voltage
•Digital Output
3.1 iSMA IO Network
The iSMA IO Network component is a network component for the Local IO Device such as the
iSMA-B-MAC36NL devices (added using Local IO Device component). The iSMA IO Network
component is the only right parent component for Local IO Device components. All the iSMA-
B-MAC36NL devices with the points inside iSMA IO Network do not consume any of the
license points.
Figure 13. iSMAIONetwork component
The iSMA IO Network component consists of the following slots:
1. Status - defines the current status of the component.
Ok - the component is working correctly,
Disabled - the component has disabled communication - the "Enabled" slot is set to "false",
Fault - indicates an incorrect configuration of the component.
