MES120, MES120G, MES120H Input/Output Modules Installation Sheet, Instruction Bulletin (ANSI), 63230-216-242A1, May 2007
You can extend the five output relays included on the Sepam Series 80 base unit by adding one, two, or three MES120 modules with 14 DC logic inputs and six output relays, one control relay output, and five annunciation relay outputs.
Three modules are available for the different input supply voltage ranges and offer different switching thresholds:
MES120, 14 inputs 24 V DC to 48 V DC with a typical switching threshold of 14 V DC
MES120G, 14 inputs 220 V DC to 250 V DC with a typical switching threshold of 155 V DC
MES120H, 14 inputs 110 V DC to 125 V DC with a typical switching threshold of 82 V DC
