It sounds like you're looking for a safety PLC or a programmable safety relay. Depending on how much safety I/O you need, their CR30 safety relay:

Programming is done with their free CCW (connected components workbench) [ugh] or it can be integrated into a ControlLogix/CompactLogix project file if you add an Ethernet module to it.
