What this module is
The Siemens 6AG1131-6FD00-7BB1 is an active SIPLUS ET 200SP digital input module with 4 channels rated for 120..230V AC, conformal coated for extended temperature range -40..+70°C, based on the standard 6ES7131-6FD00-0BB1. It mounts on a BU type B1 base unit, occupies 20 mm width on the DIN rail, and draws 10 mA from the backplane bus. Module diagnostics are provided via a green/red DIAG LED for group error, and a green PWR LED for supply monitoring. No per-channel diagnostics or short-circuit protection.
What the ratings mean for fit
MSI is listed as No — there is no module-to-module isolation; the channels share a common reference. Plan your grouping accordingly. Firmware version V1.0 is preloaded, but FW updates are possible. I&M data (I&M0 to I&M3) is supported for asset tracking.
