Description
IO-Link Smart Solenoid Valve Connector – DIN Form B 24VDC
The Nass Magnet 612-202-0357 Smart Connector converts a conventional DIN Form B Industrial solenoid valve into an intelligent, monitored valve with IO-Link communication, condition monitoring, diagnostic functions, cycle counting, PWM power control and programmable timer operation.
Designed for pneumatic solenoid valve systems, real-time applications and IIoT predictive maintenance, the Smart Connector provides detailed information about the solenoid coil and valve without requiring replacement of the existing valve. Nass specifically identifies solenoid valve systems, real-time applications and IIoT predictive maintenance as intended applications.
Connected through a 3-pin A-coded M12 connector, it allows the valve to be remotely controlled and monitored through an IO-Link system while providing local visual status through its integrated RGB LED.
Smart Solenoid Valve Monitoring
Unlike a conventional DIN connector that simply supplies electrical power to a solenoid coil, the Smart Connector continuously monitors important electrical and operational parameters.
Available measurements include:
✓ Supply voltage
✓ Output current
✓ Output power
✓ Solenoid coil resistance
✓ Valve switching time
✓ Connector temperature
✓ Switching cycle counts
These measurements allow changes in valve and coil behaviour to be identified and used as part of a preventative or predictive maintenance strategy.
Predictive Maintenance & Cycle Counting
The Smart Connector incorporates two switching counters.
One counter provides a permanent lifetime switching count that cannot be reset, while a second counter can be reset or adjusted, for example when the connected valve or coil is replaced. Warning limits can also be assigned to the counters.
This allows maintenance intervals to be based on actual valve usage rather than simply elapsed operating time.
Advanced Valve Diagnostics
The integrated diagnostic system can detect or monitor conditions including:
✓ Valve switching behaviour
✓ Short circuit
✓ Open circuit
✓ Under-voltage
✓ Over-voltage
✓ Current limits
✓ Temperature limits
✓ Switching counter limits
Diagnostic information can be communicated through IO-Link for integration into higher-level machine monitoring and maintenance systems.
Dynamic PWM Energy Saving
The Smart Connector also provides adjustable PWM control, allowing solenoid holding power to be reduced after the valve has operated.
The valve initially receives full power during the configurable pull-in period. Once this period has elapsed, the connector switches to PWM operation.
PWM duty cycle: 10–100% adjustable
Default PWM duty cycle: 50%
Pull-in time: 5–2000ms adjustable
Default pull-in time: 150ms
Importantly, PWM operation is also available without IO-Link communication.
This provides the same useful principle as the 75% power-saving connector we just did, but here it is programmable rather than fixed.
Built-In Timer Functions – No PLC Required
A particularly useful feature that I would definitely retain prominently on the page is the ability to operate independently of IO-Link.
Available operating modes are:
✓ IO-Link Mode
✓ Always ON Mode
✓ ON-OFF Timer
✓ OFF-ON Timer
✓ ON Delay Timer
✓ OFF Delay Timer
In modes other than IO-Link, switching is performed using the programmed connector functions, so only the supply voltage is required.
ON and OFF timer values can each be programmed from 1 to 65,535 seconds, making the connector useful for autonomous repetitive or delayed solenoid valve control.
7-Colour RGB Status LED
An integrated RGB LED provides immediate visual indication of connector and valve status.
The LED can provide individually configured colours for:
✓ Valve ON
✓ Valve OFF
✓ Alert condition
✓ Communication indication
✓ Locator / Find-Me function
Configurable ON, OFF and alert colours plus locator and communication modes.
This is especially useful on machinery with multiple valves because the locator function can visually identify a particular connector during commissioning or maintenance.

Why Choose the Nass Smart Connector?
The major advantage is that existing compatible solenoid valves do not necessarily need to be replaced with purpose-built smart valves.
Nass describes the Smart Connector as a straightforward way to add monitoring and diagnostic functions to existing solenoid coils and valves for pneumatic applications.
It combines valve control, IO-Link communications, live measurement, fault diagnostics, switching counters, programmable timers, RGB status indication and PWM energy saving in one compact DIN Form B Industrial connector.
That makes it a genuinely useful retrofit route from a conventional solenoid valve to a monitored Industry 4.0 valve system.
