Safe, contact-expansion relay modules for AS-Interface are used to expand the number of available safety outputs in cases where modern electronic safe outputs cannot be used.  Because they have no mechanical components that are more prone to fail, this approach has numerous advantageous for AS-Interface networks: --Not using relays reduces the cost of the solution --The switch-off time of an electronic output is faster --Eliminating mechanical components increases total system reliability --External relays reduce the cost of replacing a failed component --Replacing just the contact expansion module is faster
