Compact RIO Controllers
Composition of CRIO PAC
Compact RIO is industrial ruggedized Programmable Automation Controller PAC that provides interface to C Series Module for I/O connectivity. Certain models carry Field Programmable Gate Array in the back plate chassis. A full Compact RIO PAC controller could be a combination of and FPGA Chassis with hot-swappable C Series modules and a pluggable real...

Operation of safety relay
The typical design of a safety relay is based on the classic 3 contactor combination. The design ensures that wiring errors do not lead to the loss of the safety function. Two relays (K1, K2) with positive-guided contacts - set of NO and NC contacts that operate together so NO and NC...
Machine Safety Integrity Level SIL
A quick google search tells us that Sil level is about probability of failure but what does it mean in terms of process engineering? I have written this brief article focusing on how expression SIL and IEC 61508 applies to our field of work.
What is SIS
If an instrument is SIS rated i.e. Safety Instrumented System,...
