8 Channel Current Analog Input Safety Module SIL 3

8 Channel Current Analog Input Safety Module SIL 3 Functional features

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

The 8 Channel Current Analog Input Safety Module SIL 3 adopts 1oo2D architecture, with 2 sets of channels for independent sampling and hardware diagnosis, and output after safe voting;

The channel adopts independent ADC chip sampling, which has the characteristics of high precision and high stability;

Complete electrical isolation between the module and the system, completely shutting out external interference;

PhotoMos switch switches scanning channels, and channels are isolated from each other. When a channel fails, it will not affect the normal operation of other channels;

Supports signal data transformation, channel input diagnosis, digital filtering, linear correction, engineering conversion and other functions;

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, ADC fault diagnosis, main crystal oscillator diagnosis and other hardware diagnostic functions, as well as CPU diagnosis (general register diagnosis, stack pointer diagnosis, Software diagnostic functions such as RAM diagnosis, Flash diagnosis, etc.), interrupt diagnosis, communication diagnosis, peripheral driver diagnosis, etc.;

When the module diagnoses a fault, the system quickly responds to the safety action corresponding to the fault to ensure production safety;
