2. PRESENTATION
The DigiRail Connect module is a device that has a series of electronic channels of analog and digital inputs and outputs (IOs) that can be ac-
cessed and controlled through serial communication ports.
Fig. 01 – DigiRail Connect Process
The DigiRail Connect module has eight models with five different channel types: digital input channels (D), analog input channels (A), digital
output channels (K), relay output channels (R) and analog output channels (O).
The configuration of the DigiRail Connect module can be performed using the NXperience configurator software, which allows you to define the
functions and mode of operation of the input and output channels and the communication ports. In addition, NXperience allows you to force values
into the analog and digital inputs and outputs and perform analysis of information about the Ethernet interface and the device.

4. INSTALATION
4.1 MECHANIC INSTALATION
The DigiRail Connect is designed to have its housing fixed to a 35 mm DIN rail, as shown in Fig. 07. The 35 mm DIN rail installation must be
carried out after the device has been configured.
Fig. 07– Mechanical installation
4.2 DIMENSION
DigiRail Connect has high quality housing, built in ABS+PC and with index of protection of IP20, which has the following dimensions:
Fig. 08 – Dimension
4.3 INSTALLATION RECOMMENDATIONS
•Electronic and analog signal drivers must run the plant separately from the output and power leads. If possible, in grounded conduits.
•The power supply for the electronic instruments must come from a proper power grid for instrumentation.
•It is recommended to use RC FILTERS (noise suppressors) in contactor coils, solenoids, etc.
•In control applications, it is essential to consider what can happen when any part of the system fails. The device's internal security features do
not guarantee full protection.
•The electrical connections must be made with the connection terminals marked on the device. Before connecting them, make sure that the
connections have been made correctly.

5. CHARACTERISTICS AND CONNECTIONS
5.1 ANALOG INPUTS
DigiRail Connect has versions with 2 channels of analog inputs, identified as A1 and A2, on its front panel. These channels are available only on
RAMIX models and are suitable for measuring temperature or any other values represented by standard linear electrical signals.
Each channel can be configured through the NXperience configurator software (see the Configuration Software chapter).
Fig. 09 – Analog inputs
The possible input types, along with their respective measuring ranges, are listed in Table 02.

Table 02 – Input types and sensor measurement ranges
Analog channels A1 and A2 are not electrically isolated from analog output channels O1 and O2, but are electrically isolated from other DigiRail
Connect channels.
For the Temperature Sensors group, the temperature unit setting is required. For the Linear Analog Signals group, the measurement range
definition is required.
For all types of input signals, it is necessary to set values for the operating parameters of the DigiRail Connect analog input channels (see Analog
Inputs section of the Configuration Software chapter):
•Sampling Rate: Allows you to set the number of readings performed each second by the analog input channel on the received input signal: 1
reading per second or 10 readings per second.
•Filter: Allows you to set the Time Constant value of a filter to be applied over the measured input signal. Parameter used to improve the
stability of the measured signal. Adjustable between 0 and 1200 seconds.

NOVUS AUTOMATION 9/34
5.1.1 FLAGS A1 – A2
The flags A1 and A2, when lit, indicate that the respective channel is enabled, not reflecting the condition or value of the signal present at its termi-
nals. In addition to indicating whether or not a channel is enabled, the flags also indicate when there is something wrong on the respective channel.
Improper conditions on the input channels are called "Error Condition" and are showed in specific paragraphs of this manual.
5.1.2 ANALOG INPUT ERROR CONDITION
It is called an "Error Condition" every condition of use or improper operation for the DigiRail Connect input channels. Many of the improper condi-
tions are identified and then flagged by the blinking of the light signal of the respective channel.
The error conditions of the analog inputs are showed in Table 03.
INPUT TYPE ERROR CONDITIONS
Temperature Sensors •Measures beyond the limits of the operating range;
•Open input / open signal.
0-20 mA •Measures above 22 mA (±0.5 mA) (*).
0-5 / 0-10 V •Measures above 10% of the upper limit (*);
•Reverse polarity.
4-20 mA
•Measurements below 3.5 mA (±0.2 mA);
•Measures above 22 mA (±0.5 mA);
•Open input / open signal;

5.2 DIGITAL INPUTS
DigiRail Connect has versions with 4 channels and 8 channels of digital inputs, identified as D1 ... D4 ... D8, on its front panel. These digital chan-
nels are suitable for receiving Dry Contact, NPN and PNP electrical signals.
Each channel can be configured through the NXperience configurator software (see the Configuration Software chapter).
Fig. 15 – Digital Inputs
The digital inputs can perform different functions, which will be defined during configuration (see Digital Inputs section of the Configuration Software
chapter). The functions available are:
•Logical State:Allows the digital input to read the logic state of the signal applied at its terminals: 0or 1.
•Counter: Allows the digital input to count the number of pulses received at its terminals. As a reference for incrementing the count, you can
use the rising edge (transition from 0to 1) or the falling edge (transition from 1to 0) of the received pulse.
•Integrator ON/OFF: Allows the sum (integration) of the time intervals measured with the digital input in logic state 0to be performed and also
the sum of the time intervals measured with the digital input in the logical state 1. It will provide the two information separate. Value displayed in
seconds.
In addition, the Integrator ON/OFF and the Counter functions have the Preset function, which allows you to set an initial value for the pulse count
or the sum of the digital input ranges to 0and 1.
For the Dry Contact signal type, there is the Debounce feature, which allows defining a time interval to be disregarded by the digital input at each
logical state transition.
5.2.1 FLAGS D1 ... D8
The flags D1 ... D8, when lit, indicate the logic state of the signal applied to the terminals of the respective digital input.
