The DigiRail Connect is a versatile DIN rail I/O module with Ethernet, RS485 and USB interface which can be easily integrated to any automation system. With a flexible mix of industry-standard inputs and outputs, it performs  analog and digital signal handling with outstanding accuracy.  Bringing the Industry 4.0 to the DIN rail level, the connectivity of DigiRail Connect allows it to be used as a Modbus RTU slave in RS485 networks or as a Modbus TCP server over Ethernet. Specially designed to comply with international electromagnetic compatibility standards, it ensures robustness and reliability in the most demanding industrial applications. 

Universal Analog Inputs
The RAMIX-DO and RAMIX-RL have two universal  analog inputs which are software programmable for input type.  The two inputs are electrically insulated from the serial interface and the module power supply.  Features include:

• Analog inputs: programmable for thermocouples J, K, T, N, E, R, S , B,   Pt100, Pt1000, NTC, 0-60 mV, 0-5 Vdc, 0-10 Vdc, 0-20 mA, 4-20 mA
• Cold junction compensation for thermocouples and compensation for Pt100, PT1000 3-wire cables
• Open loop detection for thermocouple
• 10 Sample/sec sample rate
•  Analog input resolution: 16 bits
• Programmable filter

Analog Outputs
The RAMIX-DO and RAMIX-RL also have two analog outputs. Features include:

• Configurable ranges of 0-20 mA, 4-20 mA, 0-10 V
• Settable power on state level
• Safe Value Watchdog - Allows you to set a value for the analog output in case of loss of communication.
• 12 bit resolution

Digital Inputs
All DigiRail Connect modules have digital inputs.  The DMIX models have 8 digital inputs and the RAMIX models have 4 digital inputs. Features include

• Programmable Measurement Function
• Logic Status
• Rising or Falling Edge  Counter (up to 250Hz for PNP or NPN, 10HZ for dry contact closure)
  
• Integrator (counts time in seconds when triggered by logic status)

• Programmable Signal Type
• Dry Contact with programmable debounce time
• NPN
• PNP
• Preset - allows an initial value to be set for the Rising Edge, Falling Edge, and Integrator ON/OFF counters.

 Digtial and Relay Outputs
The RAMIX-DO has 3 digital outputs and the DMIX-DO has 8 digtial outputs.  The RAMIX-RL has 2 relays and the DMIX-RL has 4 relays. Digital Output/Relay Features include:

• Programmable Actuation Mode
• Logical Status
• Pulse - The output will turn on for a specific time interval (set in the Pulse Duration parameter) and then return to the OFF status
• Pulse Train - The  output will create a defined number of pulses (set in the Number of Pulses parameter), with a defined duration (set in the Pulse Duration parameter) and in a defined period (set in the Repetition Period parameter).
• Power On State
• Safe Status Watchdog - Allows the output state to be set in case of communication failure

Ethernet, RS485 and USB Communication
All of the DigiRail Connect have Ethernet and RS485 communications.  The Ethernet connection uses Ethernet TCP protocol and the RS485 uses Modbus RTU protocol.  You can configure DigiRail Connect to operate in Gateway mode between a Modbus-TCP network and a Modbus RTU network.  The DigiRail Connect also has a USB port which is ideally intended for configuring and diagnosing the monitored process.
