SIMATIC S7-1200 SB 1221 high-speed digital input signal board

Product Summary

The Siemens 6ES7221-3BD30-0XB0 is an SB 1221 digital input Signal Board for SIMATIC S7-1200 controllers. Siemens specifies four 24 V DC sourcing inputs with a maximum published frequency of 200 kHz, allowing a compact controller to add high-speed input capability without a full-width signal module. It is relevant to pulse acquisition, machine event detection and exact-order-number replacement projects. Before ordering, confirm the CPU supports the Signal Board, verify the complete suffix, input wiring, sensor output type, voltage level and required input frequency.
