Features:
- Sixteen 24 V DC digital input channels
- Galvanically isolated field inputs
- Designed for a 20-pole S7-300 front connector
The Siemens 6ES7321-7BH01-0AB0 is a SIMATIC S7-300 SM 321 digital input module. It receives sixteen 24 V DC field signals and transfers their states to the S7-300 system.
The input circuitry is isolated from the backplane bus. The module uses the documented 20-pole front connector and must be configured for the installed S7-300 station.
Before ordering Siemens 6ES7321-7BH01-0AB0, confirm the complete order code, documented configuration, and connection requirements for the installed system.
