This module, model 6ES7221-1BF22-0XA0, is a digital input expansion module for the Siemens SIMATIC S7-200 series, specifically designed for S7-22X series CPUs. It provides eight 24V DC digital input channels, supporting both sink and source current wiring methods, enhancing field wiring flexibility. Each input channel has a signal "1" voltage range of +15V to +30V DC and a "0" voltage range of 0 to 5V DC, with a typical input current of 4 mA.
The 6ES7221-1BF22-0XA0 Siemens Digital Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The input delay is fixed, with a maximum response time of 4.5 ms from "0" to "1", suitable for acquiring conventional switching signals. For sensor connectivity, the module supports two-wire sensors with a maximum quiescent current of 1 mA. To achieve electrical isolation, the module uses optocouplers to isolate the channels from the backplane bus and provides inter-group isolation in groups of four, thereby improving the system's anti-interference capability.
This module draws 5V DC power from the S7-200 system backplane bus, with a maximum input current of 30 mA and a typical power consumption of 2 W. The maximum permissible wiring distance is 500 meters when using shielded cable and 300 meters when using unshielded cable. The module uses pluggable I/O terminals for connection and measures 46 mm (W) x 80 mm (H) x 62 mm (D), weighing approximately 150 grams. This module is a standard component for expanding the digital input functionality of S7-200 series PLC systems and is suitable for automation applications requiring the addition of local or remote digital signal acquisition points.
