CZSR8401-1A is a safety relay control module, which could control its
output contacts in segregation through LVDC 24V control signal, and its
output circuit could withstand load with voltage of 230V. There are triple
redundant technology and fuse protection in the output circuit in order
to prevent contacts welding. The internal circuit design with the Fail-
Safe technology could achieve SIL3 of the Functional Safety Integrity
Level in accordance with IEC61508 international standard.
