According to the digitization of the "last meters" in the automation technology, nass magnet as an expert for pneumatic valve actuators presents the innovative valve driver with IO-Link interface, implemented in a DIN interface connector.

Connected valves can be remotely controlled and monitored via the network using this peer to peer interface.

Useing with a master, diagnostic data for the connector, solenoid coil and valve system can be retrieved, monitored and connected to cloud-based systems.

For the use in extreme environmental conditions nass magnet also offers robust versions in the protection classes IP65/IP67.

Quick and simple connection

In order to speed up conventional cable installation, IO-Link connectors from nass magnet are marketed with a pre-assembled M12 connector. Due to M12 connector it can now be easily connected to a control unit or to a master, thus completely eliminating the need for on-site cable assembly.

The cable used is an unshielded 3 core signal cable. The advantage is that digital signals are less sensitive to interference than conventional analog signals.

Status monitoring

Using IO-Link protocol, the connector continuously communicates with prozess data with the master and allows electrical signals from the connected valve system to be checked. This makes it possible to detect whether the valve system is electrically pulled whether it is energized.

By asyncronous, on-request data transfer can several condition variables be raeched like supply voltage, output current, switch on resistance of the coil and their actual power consuption.

The connector with IO-Link from nass magnet is using communication mode COM 2. This enables the transmission of the actual process signal as well as the transmission of switching signals and diagnostic messages. COM 2 has a transmission rate of 38.4 kbaud and can transmit 8-8 bits of process data to the controller every 2 ms.

Preventive maintanence

To monitor the product lifecycle, the smart connector can detect and store switching cycles. To observe the whole lifecycle ther is one counter, whitch can not be resteted. And there is an other one which can be set up by the user like in your car.

Ther is a possibility to every counter and to almost every measured parameter to set up a limit. In case of reaching this treshold an automatic event can be generated to handle them in higher levels.

Thanks to the switching cycle counter in connectors, failures can be prevented and product life cycles analyzed.

PWM mode

To reduce the power consumption of the connected solenoid coil, smart connector offers PWM mode. The Pulse Width Mode allows to regulate the output current.

Switch on time can be set up to maximum 2.000 millisecond to ensure the perfect pull-in of the valve. In this phase the coil recives the full power. After switch-on time, the PWM mode is activated. The required power reduction can be achieved by adjusting the duty cycle parameter.

The PWM operation works also in off-line* modes.
(*Without using IO-Link communictaion.)

Diagnostic data

The IO-Link connector has numerous diagnostic data:

  • Supply voltage
  • Output current
  • Load resistance
  • Power consumption of the solenoid coil
  • Own temperature
  • Switch-on time of the valve

RGB LED

Customize your connector!

Different output status can have different LED color.

The "Find me" mode

The nass magnet smart connector can be switched to a "Find me" mode. This mode is useful if the solenoid coil, the valve system or the connector itself (assuming it is still electrically powered) should fail. An integrated RGB LED now indicates the location of the connector to be checked by the maintenance service by flashing in different colors.

Data Storage

Configuration memory

The configured parameters of the connector are stored in the data storage and can be read out from the affected connector and transferred to the replacement product in case of a failure.

It will save time and cost in case of replacement.
