Key ratings — what they mean for fit
The 6ES7131-4EB00-0AB0: Input voltage is pure AC: 120 V at 47 to 63 Hz. Signal "1" pulls 3 to 9 mA typical, and quiescent current for 2-wire sensors is capped at 1 mA — though this module is not designed for 2-wire sensors. Response time: 15 ms on, 25 ms off, so factor that delay into your scan cycle if you're chasing fast events. Isolation tested at 2 500 V DC. Power loss is only 0.5 W, so it won't push the enclosure thermal budget. Cable runs up to 1 000 m shielded or 600 m unshielded.
