About Spiroflow Automation Safety PLCs

Spiroflow Automation Safety PLCs can run logic for machine control but also has additional hardware for redundancy and self-checking. They are configured to meet performance and safety integrity levels required for a certified or valid safety system.

A safety PLC contains redundant hardware for self-checking and redundant I/O for dual channel inputs, E-STOPs, and other safety critical functions. Dual channels are required for redundancy and the I/O must be configured for both I/O monitoring and alarming. Monitoring ensures that if a wire is removed or a relay contact fails on a field device (such as a level instrument) an alarm will be triggered and the process will be automatically stopped as programmed, without requiring operator intervention.
