Product description
Siemens 6ES7421-7BH01-0AB0 is an SM 421 digital input module for the SIMATIC S7-400 automation system. The module has 16 digital inputs for 24 V DC. Its input signals conform to IEC 61131 Type 2. The permitted voltage range extends from 20.4 to 28.8 V DC. The input delay can be configured to 0.05 / 0.1 / 0.5 / 3 ms. Current consumption from L+ is a maximum of 120 mA. The backplane-bus current is documented as a maximum of 130 mA at 5 V DC. The module has two sensor supplies rated at 120 mA each. Its diagnostic function and hardware interrupt are configurable. The channels are electrically isolated in groups of 8 and from the backplane bus. Siemens lists a typical power loss of 5 W. These characteristics describe signal acquisition, diagnostics and electrical integration for this specific SM-421 version. The Siemens data sheet gives overall dimensions of 25 × 290 × 210 mm in width × height × depth order. Its weight is stated as ca. 600 g. The enclosure dimensions describe the module itself; additional room for the front connector, wiring and maintenance access depends on the installed cabinet arrangement. These mechanical data remain central comparison values for installation planning, handling, storage and transport. For replacement comparison, the full MLFB, input count, signal voltage, input characteristics, delay, diagnostic configuration and electrical isolation are relevant. The designation 6ES7421-7BH01-0AB0 distinguishes this fast SM-421 variant from other S7-400 input modules with a different channel count, response time or electrical design.
