16-Channel Digital Level Output Safety Module SIL 2

16-Channel Digital Level Output Safety Module SIL 2


China UW5917S 16-Channel Digital Level Output Safety Module SIL 2 implements functions such as bit value encapsulation, output latch, readback monitoring, comprehensive diagnosis, and safe voting of 16-channel digital level output signals, achieving high reliability, high availability, high security, Strong adaptability design.

16-Channel Digital Level Output Safety Module SIL 2 Features:

The system automatically identifies the module type and enables plug-and-play;

The 16-Channel Digital Level Output Safety Module SIL 2 adopts 1oo2D architecture, with two sets of channels independently outputting and mining diagnosis after safe voting;

Photoelectric isolation is used between the signal and the system, with an isolation voltage of 2000V;

Channels are isolated from each other, and channel failure does not affect the normal operation of other channels;

The system power distribution adopts a +24V power supply that is independent of the system power supply to ensure complete isolation from the system power supply;

Supports channel output bit value encapsulation, output latch control, output voting processing and other functions;

The channel adopts data output readback confirmation method to ensure the reliability of data output;

It is used for safety loops and has relatively complete module fault diagnosis functions, including power supply circuit over- and under-voltage diagnosis, channel fault diagnosis, channel safety failure diagnosis, main crystal oscillator diagnosis and other hardware diagnostic functions, as well as CPU diagnosis (general register diagnosis, stack pointer diagnosis , RAM diagnosis, Flash diagnosis, etc.), interrupt diagnosis, communication diagnosis, peripheral driver diagnosis and other software diagnostic functions;

When a module diagnoses a fault, the system quickly responds with safety actions corresponding to the fault to ensure production safety.
