How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Siemens 6ED1055-1MA00-0BA2 LOGO! AM2 is an analog expansion module for the LOGO! 8 logic module, adding 2 analog inputs configurable for 0-10 V or 0/4-20 mA signals. It runs on 12 or 24 V DC supply, mounts on a 35 mm DIN rail, occupies 2 spacing units, and carries IP20 protection.
Two analog inputs with switchable 0-10 V or 0/4-20 mA ranges cover both potentiometer/sensor voltage signals and current-loop transmitters from the same module, so the input type is set per project rather than fixed at order time. The 12/24 V DC dual rating lets it run from the same supply as the LOGO! base module without a separate power source. Class B EMC emission rating (EN 55011) clears it for use in residential-adjacent installations, not just industrial-only sites.
Adds analog sensing (temperature transmitters, pressure transducers, level sensors) to LOGO! 8-based small machine and building-automation control panels where the base module's inputs are digital only.
