Surge protection is integrated into modular connector
The Han SP module allows both digital and analogue circuits are securely protected, whether single ended or differential signals are used without a common reference signal.
These signals are generally differential types such as bus interfaces up to 5 MHz or analogue signals such as 0/4-20 mA or 0/2-10 V. Both types – two-channel types for differential signals and four-channel types for signals with common reference potential – can transmit nominal 24 V DC and up to 0.5 A. The protection level is approximately 50V, depending on the type.
Transients, which can disturb signal circuits and destroy electronic devices, are discharged to the ground via an appropriate spring element and the grounded Han-Modular hinged frame. This ensures interference-free transmission of the signal.
When used correctly, the surge protection modules reduce the number of operating faults, increase the service life of the production line and ultimately increase plant uptime. Additional costs are avoided and the profitability of the production plant is maintained.
