6ES7455-1VS00-0AE0 Siemens | FM 455 S Step and Pulse

Product Overview

The Siemens 6ES7455-1VS00-0AE0 is an FM 455 S control module for SIMATIC S7-400 systems, providing 16 step and pulse control channels. It combines 16 analog inputs, 16 digital inputs, and 32 digital outputs in a single module. Weighing approximately 1,400 g, this controller supports thermocouples, Pt100 resistance thermometers, and standard signals for comprehensive process control with pulse output capability.

Technical Configuration

This module operates from 24 V DC load voltage with a permissible range of 20.4 to 28.8 V. It draws a maximum of 400 mA (typical 330 mA) from load voltage without load. The 16 analog inputs accept thermocouples or 2-wire connections, while 8 channels support Pt100 or 4-wire connections. The 32 digital outputs feature electronic short-circuit protection and inductive shutdown voltage limitation to L+ (-1.5 V). Potential separation between channels and backplane bus uses optocouplers, tested at 500 V DC isolation.

Technical Specifications

Installation Guide

Install the FM 455 S module in a compatible S7-400 rack slot and secure both 48-pin front connectors. Connect 24 V DC load voltage within the 20.4-28.8 V range. Use shielded cable for analog signals with maximum 200 m length (50 m for 80 mV and thermocouple inputs). Verify digital output loads fall within the 240 Ω to 4 kΩ resistance range. Internal or external Pt100 temperature compensation is parameterizable for thermocouple measurements.

Engineering Advantages

This module integrates 16 closed-loop controllers with 16 AI, 16 DI, and 32 DO in a single unit, combining step/pulse control with analog measurement. The 32 digital outputs provide twice the output density of the FM 455 C, reducing module count in high-channel applications. Electronic short-circuit protection and inductive shutdown voltage limitation safeguard connected loads. Parameterizable 12-bit or 14-bit resolution suits both standard and precision measurement tasks. Optocoupler isolation between channels and backplane bus protects the system from field transients.
