2Introduction
The Omega Link SP-014 Process Monitoring Smart Probe provides an easy way to integrate process signals into the
Omega Link Ecosystem. The SP-014 accepts standard process signals through its M12 5-pin connector and Omega Link
Smart Interfaces through its M12 8-pin connector. The optional M12.8-T-SPLIT Sensor Splitter can be used to access
the Discrete I/O pins on the M12 8-pin connector. The optional M12.5-S-M-FM and M12.8-S-M-FM mating connectors
can be utilized to easily connect wire leads to the SP-014 or Sensor Splitter. Each of the 3 process inputs may be
independently configured as 0-24 mA, 0-1.0 VDC, or 0-2.0 VDC inputs. A mixed-mode configuration option allows for the
measurement of one process input and one digital pulse input which supports frequency (rate), pulse width, pulse
duty cycle, and pulse counting (totalizer).
The Omega Link SP-014 features 2 configurable discrete I/O pins. These can be used for a myriad of applications
including driving relays, physical alarms, or sensing dry contacts like door switches. The SP-014 can also be utilized as
an edge controller, with autonomous independent decision-making capabilities to generate local alarms or provide
control outputs based on sensor inputs.

5.3.2.1.1 Pulse Measurements
Pulse measurements include Digital Input (DIN), Frequency (RATE), Pulse Width (WIDTH), Duty
Cycle (DUTY), and Up Counter/Totalizer (COUNT). All measurements are derived from signal
transitions and an internal 32.768 kHz time reference. The pulse input signal is read on the Pulse
A input (pin 2) and the reset input signal is read on the Reset input (pin 5). When the reset input
is activated then the pulse input value is zeroed for all pulse measurement types.

13 | M 5 7 5 2
The Digital Input (DIN) mode reports the binary value on the DIN pulse input pins. Note the DIN
inputs replace the functionality of the Pulse and Reset inputs.
Two measurement modes are used when measuring Frequency (RATE). If the measured
frequency is greater than 100 Hz the total number of pulses/second is used to determine the
frequency. If the measured frequency is less than 100 Hz the time between rising edges is used
to calculate the frequency.
The Pulse Width (WIDTH) setting measures the active portion of a periodic signal in msec. The
pulse input may be configured to be active high or active low to measure the positive or
negative portion of the pulse width. See the Input Configuration Diagrams section below for
details.
The Duty Cycle (DUTY) setting measures the percentage of time a pulse is active (high) over the
total period of the signal. The duty cycle measurement allows reading the input from PWM
control signals.
Frequency (RATE) = Total Count/second
if > 100 counts/second

The Up Counter/Totalizer (COUNT) mode counts the number of rising edges until the Reset
input is activated. The Reset input can be configured to be active high or active low. See the
Input Configuration Diagrams section for details.

5.3.2.1.2 Input Configuration Diagrams
Both the Pulse and Reset input pins can be independently set to either have an internal 1.5k Pull
Up (PU) or Pull Down (PD) and can be set to be either Active High or Active Low by selecting
Normally Open (NO) or Normally Closed (NC) in the SYNC input configuration interface. Some
typical circuits are shown below:
Figure 15: Active High/Low Circuit Examples

16 | M 5 7 5 2
The Pulse input pin may also be configured for low-level mV input signals. The four selectable ranges determine
the turn-on threshold (TH) and the turn-off threshold (TL) which are used to set the ACTIVE level of the digital
input.
5.3.3 Discrete Input/Output (DIO)
The Omega Link SP-014 features 2 configurable discrete I/O pins; DIO_0 and DIO_1. These can be used for a
myriad of applications including driving relays, physical alarms, or sensing dry contacts like door switches. The
user may configure the polarity of the inputs (active HIGH or active LOW) or Disable the DIOs to utilize the
outputs (ON/OFF, PWM, SERVO).

17 | M 5 7 5 2
The Discrete I/O input shares the output circuitry. The internal process drives the output control signal to turn
on the output driver which will force the output low. When the state of the DIO input signal is to be read the
processor applies 3.3 VDC to the Input Bias signal and reads the level detected at the Input Sense. If the output is
inactive an external signal may be used to force the input level low. A diode protects external positive voltages,
allowing the output driver to activate loads greater than the internal 3.3 VDC.
5.3.3.1 Setting DIO as an Input
To use a DIO pin as an input, make sure it is set to Active Low (default) in the Output Tab in SYNC.
Then, in the Input Tab, select a Type from the drop-down which includes DIO. Each DIO pin has an
internal pull-up, but to save power, the internal pull-up is only active when the unit takes a reading.

5.3.4 Advanced Scaling Options
The Omega Link SP-014 allows for advanced scaling options on process and pulse inputs only. The Advanced
Scaling checkbox can be selected to expand additional configuration options. A gain and/or offset can be
applied to the input reading and the displayed unit can be changed.
To apply a gain or offset to the input, expand the Scaling menu and ensure that Apply Scaling is checked. There,
the gain and offset values can be adjusted. Both positive and negative values may be entered as well as decimal
numbers. The equation for the scaled input value is given below.
 󰇛 󰇜
The displayed units can be changed by entering a new value in the Unit field and clicking Apply Settings. This
field is limited to a maximum of 4 characters. Note that changing the Unit field does not change the base unit
type, only the display name. The Lock checkbox must be selected to use the user-defined Unit field. Unchecking
the Lock checkbox and clicking Apply Settings will revert the unit display back to the default setting.
The screenshot above shows an example application for advanced scaling with renamed units. A fan tachometer
with a 500 Hz signal is connected to the Pulse Rate input. The fan outputs 2 pulses per revolution, so to convert
to rotations per minute (RPM) the reading must be divided by 2 which is accomplished by setting the Gain to
0.5. The units can then be renamed to RPM and will display as such.
Figure 21: Advanced Scaling Example

19 | M 5 7 5 2
5.4 Output Configuration
The SP-014 offers two discrete outputs that share circuitry with the discrete inputs. If an output is to be used then
the corresponding input pin must be set to Disable. See section 5.3.3 Discrete Input/Output (DIO) for more
information.
There are three types of output options –On/Off, Pulse-Width Modulation (PWM), or Servo. See section 5.4.1 for
more information on each type.
Outputs may be configured as either Active High or Active Low. When configured as Active High the output conducts
normally and becomes high impedance when activated. When configured as Active Low the Open-Drain output is
high impedance normally and will conduct when activated.
An output may be controlled in one of three ways –a scaled mapping to an input, an on/off control from an input
setpoint, or as an input alarm. Sections 5.4.2 through 5.4.4 describe these output control methods.

5.4.1 Device Output Range/Types
There are three types of output options –On/Off, Pulse-Width Modulation (PWM), or Servo. This section
describes these output options.
5.4.1.1 ON/OFF Output Type
The ON/OFF output mode switches the output to be a binary ON or OFF. Depending on if the output is
configured as Active Low or Active High, the ON/OFF mode can correspond to different polarities.
5.4.1.2 Pulse-Width Modulation (PWM) Output Type
Pulse-Width Modulation (PWM) controls the amount of power given to a device by cycling the on/off
phases of a digital signal. PWM consists of a duty cycle and frequency. The Duty Cycle measures the
amount of time a signal is in the ON state as a percentage. The frequency controls how fast the PWM
cycle is repeated. Users can select between the following settings:
Option

Description
Rate
100 Hz
Signal has a constant 100 Hz frequency with 0-100% Duty Cycle
10 Hz
Signal has a constant 10 Hz frequency with 0-100% Duty Cycle
1 Hz
Signal has a constant 1 Hz frequency with 0-100% Duty Cycle
0.1 Hz
Signal has a constant 0.1 Hz frequency with a 0-100% Duty Cycle
Signal Type
Active LOW
When the output is active, it is pulled to ground (LOW)
Active HIGH
When the output is active, it is in a high impedance state
5.4.1.3 SERVO Output Type
The SERVO output allows driving servo motors that control position. A Servo output is a special case of
the PWM output, where the ON time varies between 1.0 msec and 2.0 msec or between 0.5 msec and
2.5 msec, with the lower bound representing 0 degrees and the upper bound representing 180 degrees
of angular travel. The typical non-critical frequency is 50 or 100 Hz. Servo outputs are always active high.
