Siemens 6ES5244-3AA22 Temperature Control Module

This temperature control module manages thermal processes for SIMATIC S5 systems. It reads thermocouple sensors and adjusts heating or cooling outputs accordingly. Therefore, this component suits injection molding, ovens, and heat treatment applications.

Physical Dimensions and Weight Specifications

The Siemens 6ES5244-3AA22 occupies one standard slot in the S5 rack. Its housing measures 233 mm in depth for backplane connectivity. The module weighs approximately 0.45 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Siemens 6ES5244-3AA22 provides a 48-pin front connector for sensor wiring. A separate 20-pin backplane connector supplies power and data signals. The front panel carries LED indicators for each control channel. Hence, operators can monitor heating and cooling status at a glance.

Component Count and Channel Configuration

This module contains one main board with four independent PID control loops. Each channel includes a 16-bit analog-to-digital converter for temperature readings. You will also find four digital outputs for actuator control. An onboard cold junction compensates for thermocouple reference errors.

Energy Storage and Power Consumption

The Siemens 6ES5244-3AA22 draws 140 mA from the 5V backplane supply. A small capacitor bank stores calibration data for 24 hours. This storage retains sensor linearization tables during brief power interruptions. Therefore, the module resumes accurate control without recalibration after restarts.

Control Performance and Sampling Rate

The module samples each temperature channel every 200 milliseconds. It updates the PID outputs at the same interval for smooth regulation. Users can configure independent setpoints and alarm limits per channel. This flexibility supports mixed thermal zones within a single machine.
