Product Overview

The Siemens 6ES7221-3BD30-0XB0 is a SIMATIC S7-1200 SB 1221 digital input signal board manufactured by Siemens AG. It provides four digital inputs with a rated input voltage of 24V DC and a manufacturer-specified high-speed input rating of 200kHz. This model uses a current-sourcing input configuration and is designed to expand the digital input capability of supported SIMATIC S7-1200 controllers. The signal board can be installed directly into the compatible CPU signal board location, without using a conventional side-mounted I/O expansion module arrangement. Its compact housing measures approximately 38 × 62 × 21mm, with typical power loss of 1W. Input delay is parameterizable and digital input status indication is supported. The manufacturer specifies an operating ambient temperature range of -20°C to +60°C, subject to installation conditions. The supplied actual packaging photographs identify model 6ES7221-3BD30-0XB0, the SB 1221 product family, 4 × 24V DC inputs and 200kHz operation. The internal signal board itself is not visible in the supplied photographs. Buyers should verify the exact CPU model, input signal type and high-speed requirements before ordering.
