Selection Notes

AI581-S brings 4-20 mA analog sensing into a SIL2/SIL3 safety loop, so it fits applications such as pressure or level transmitters feeding an emergency shutdown function rather than standard process monitoring. The 14-bit resolution on each of the 4 channels is fixed, so the only real choice against its sibling is environment: pick the AI581-S-XC variant instead when the installation needs the extended -30 to +70 C operating range.
