MeloAuto-Trusted PLC & DCS Parts Supplier
This Siemens monitoring module provides comprehensive supervision for critical system parameters. The Siemens 6ES5313-3AA12 continuously tracks voltage levels and temperature conditions within control cabinets. Its design prioritizes early fault detection to prevent unplanned production stoppages. This module suits applications requiring constant vigilance over power supply integrity. The Siemens 6ES5313-3AA12 offers adjustable threshold settings for flexible system protection. Its compact form factor allows integration into existing S5 rack configurations.
Physical Dimensions and Mounting Details
The module measures 232 mm in height and 25 mm in width. Its overall depth reaches 160 mm including the front connector assembly. This unit weighs approximately 0.45 kilograms without additional accessories. The housing supports standard 35 mm DIN rail installation within the rack. Its narrow profile conserves valuable space in densely populated cabinets. The Siemens 6ES5313-3AA12 features a 20-pin front connector for all wiring connections. This connector accepts conductor cross-sections from 0.5 mm² to 2.5 mm².
Monitoring Functions and Electrical Specifications
This module supervises two independent 24 V DC supply circuits simultaneously. Each channel includes a built-in comparator for precise voltage deviation detection. The monitoring range spans from 18 V to 30 V DC with 0.1 V resolution. A temperature sensor tracks ambient conditions within the enclosure. This sensor covers a range from -25°C to 85°C for comprehensive coverage. The Siemens 6ES5313-3AA12 draws a typical current of 80 mA from the backplane. An internal energy storage capacitor holds 1000 µF for brief power dips. This capacitor provides a hold-up time of approximately 5 milliseconds.
Outputs and Status Indication
Two relay outputs signal alarm conditions for each monitored parameter. Each relay handles up to 2 A at 24 V DC or 250 V AC. The module provides a collective fault indicator on the front panel. An LED array shows the status of each individual monitoring channel. The Siemens 6ES5313-3AA12 includes a reset input for manual fault acknowledgment. This reset input accepts a 24 V DC pulse of at least 100 milliseconds.

Application and Configuration Guidelines
Install this module in any slot of the S5 series rack system. Connect the monitored power supplies to the designated input terminals. Set the upper and lower trip points using the onboard potentiometers. Use the relay contacts to trigger audible alarms or shutdown sequences. The Siemens 6ES5313-3AA12 operates effectively between 0°C and 60°C. Ensure proper airflow around the module for accurate temperature measurement. Test the alarm functions after installation to confirm correct wiring. Periodically verify the threshold settings during routine maintenance schedules. The module’s diagnostic LEDs simplify troubleshooting during system checks.
