Siemens 6ES7321-1FH00-0AA0 SIMATIC S7-300 Digital Input SM 321, 16 DI, 120/230V AC Original Brand New

Overview

The Siemens 6ES7321-1FH00-0AA0 (SM 321) serves as the interface between the SIMATIC S7-300 PLC and external process signals. This digital input module is specifically engineered to convert high-voltage AC signals from the field (sensors, switches) into the internal signal level of the PLC.

Key Benefit

• Space-Efficient Design: Compact S7-300 form factor allows for high-density configurations in control cabinets.

• High Voltage Compatibility: Directly connects to 120V or 230V AC industrial power without needing additional signal converters.

• Galvanic Isolation: Ensures the safety of the CPU and internal electronics by isolating the field signals from the backplane bus.

• Proven Reliability: Part of the globally trusted SIMATIC S7-300 family, ensuring long-term availability and support.

Functionality

• Signal Processing: Converts 120/230 V AC binary signals into digital logic for the S7-300 CPU.

• Status Indication: Features green LEDs on the front panel to indicate the switching status of each of the 16 input channels.

• Easy Installation: Mounts easily onto the S7-300 DIN rail and connects via a standard 20-pole front connector.
