Product Description: Siemens 6ES7355-0VH10-0AE0

The Siemens 6ES7355-0VH10-0AE0 is the FM 355 C module for the SIMATIC S7-300 automation system. It integrates four universal analog inputs, eight digital inputs and four analog outputs in a single 80 mm-wide module. Designed for continuous operation, it consolidates mixed-signal I/O and control functions—eliminating the need for separate modules and reducing cabinet footprint.

Key Features

• Mixed-Signal I/O: 4 analog inputs, 8 digital inputs, 4 analog outputs
• Analog Input Flexibility: Supports voltage (±10 V, 0–10 V) and current (0–20 mA, 4–20 mA) signals
• Digital Inputs: 24 V DC, high- speed sensing for switches and sensors
• Analog Outputs: Configurable 0–20 mA or 4–20 mA with 12-bit resolution
• Continuous Operation: Industrial-grade design for 24/7 use
• Hot-Swap Capability: Module can be replaced under power without interrupting the rack bus
• On-Board Diagnostics: Status LEDs for power, bus integrity, and channel faults
