Product Description: 6ES7332-5HF00-0AB0

The 6ES7332-5HF00-0AB0 is a high-resolution analog input module (SM 332) for the SIMATIC S7-300 PLC system. It provides eight galvanically isolated, 4-wire 0…20 mA current inputs with 12-bit resolution, enabling precise measurement of process signals. Plug-in mounting on the S7-300 backplane delivers power and data without additional wiring. This module supports per-channel diagnostics (open-circuit, overrange), configurable filtering, and status LEDs, making it ideal for medium-complexity process and machine automation tasks.

Key Features

• Eight isolated 0…20 mA current inputs, 12-bit resolution
• 4-wire input topology for highest measurement accuracy
• Per-channel diagnostics: open-circuit and overrange detection
• Configurable input filtering (STEP 7/TIA Portal)
• Status LEDs for each channel and module health
• 40 mm module width for high I/O density
