Siemens SIPLUS S7-1200 SB 1221 Digital Input Board About
The Siemens 6AG1221-3AD30-5XB0 is a highly ruggedized SIPLUS S7-1200 SB 1221 digital input signal board engineered to expand localized logic capabilities in aggressive industrial environments. Based on the standard commercial 6ES7221-3AD30-0XB0 model, this hardened variation features a factory-applied conformal coating. This specialty shield safeguards internal micro-circuitry against fine conductive dust, high humidity, moisture condensation, and corrosive chemical gases. It operates reliably across an extended temperature envelope of -40 C to +60 C and safely handles cold-weather starts down to -25 C.Designed as a space-saving accessory, the unit slots directly into the front-facing option board bay of a host S7-1200 CPU, preventing any increase to the fixed physical footprint on the DIN rail. The device provides 4 digital inputs designed for 5 V DC current-sourcing (PNP) signal topologies. Operating at an ultra-fast maximum input frequency of 200 kHz, it serves as an optimal solution for capturing high-speed pulse inputs from precision machinery, proximity sensors, or rotary encoders.
