WAGO-I/O-SYSTEM 750 

 

 

750-527 4DO 30V AC/DC 2.0A SSR 

Manual 

 

Version 1.0.0  

 

 

 

 

Do not reverse the polarity of connection lines! 

Avoid reverse polarity of data and power supply lines, as this may damage the 

devices involved. 

 

 

 

 

 

Avoid electrostatic discharge! 

The devices are equipped with electronic components that may be destroyed by 

electrostatic discharge when touched. Please observe the safety precautions 

against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the 

devices, please ensure that environmental factors (personnel, work space and 

packaging) are properly grounded. 

 

 

 

 

 

Semiconductor relay outputs require suitable fuses!  

The semiconductor relay outputs are not continuously short-circuit-protected and 

must not be overloaded. To prevent destruction and avoid additional hazards and 

damage to your system, each semiconductor relay output must be equipped with 

adequate overcurrent protection.  

This protection can be ensured by, e.g., adequate electronic fuses or safety 

fuses.  

When selecting overcurrent protection, pay attention to the current limit values 

specified for the semiconductor relay outputs and the load-carrying capabilities of 

the connected circuits! 

 

 

 

 

 

Restrict induction voltages! 

 

Residual inductive currents when inductive loads are switched off can damage 

the electronics in I/O modules. Use a suitable protective circuit to limit induction 

voltage!  

Suitable options include:   

-  

a recovery diode (DC voltage) or   

-  

a varistor in parallel to a load (AC voltage).

 

 

 

 

 

 

Do not exceed maximum switching frequency! 

 

Exceeding maximum switching frequency can destroy the I/O module.
