restart for the various channels

Description

The STEVAL-IFP019V1 demonstration board

shows the features of the VNI4140K-32 quad

high-side smart-power solid-state relay.

The application offers robustness and complies

with EMC industrial standards. It implements

short-circuit/overload protection and also thermal

management, achieving best-in-class MTBF

values. The reference design is suitable for use in

programmable logic controllers (PLCs) as well as

to drive generic loads which require up to 1 A of

nominal current (the typical current limitation is

80 m

Ω typical @ 25 °C per channel) the device

allows very low power consumption during

operation and for this reason it offers an ideal

solution for IP65 / IP67 requirements. The

VNI4140K-32 is compliant with IEC 61131-2

(international standard for programmable

controllers).
