Maximum response times of EM 1 F-RO DC24V/5A AC24..230V/5A
The maximum response time of EM 1 F-RO DC24V/5A AC24..230V/5A (under error free
circumstances and during the presence of errors) is the sum of:
• The maximum response time of the fail-safe output, used for activating the F-RO-module
• The switching time or the relay release time of the F-RO-module (refer to the Technical
