Product Overview

The Siemens 6ES5454-7LB11 is an eight-channel digital output module for SIMATIC S5-115U-series systems. Each output switches a 24 V DC load at a rated current of 2 A. Unlike the 16-output 7LA12 version, this model provides eight outputs with optocoupler isolation per channel. Siemens also specifies a 10 W maximum lamp load per output.

Technical Specifications

Parameter	Value
Manufacturer	Siemens
Model	6ES5454-7LB11
Product Family	SIMATIC S5
Module Type	Digital output module
Number of Outputs	8
Rated Load Voltage	24 V DC
Permissible Load-Voltage Range	20–30 V DC
Rated Output Current	2 A per output

Features

• Eight digital outputs
• 24 V DC rated load voltage
• 2 A rated output current per channel
• Individually isolated outputs
• Fuse-based short-circuit protection for each output group

Model Benefits
• 2 A per output: Handles suitable DC field devices with higher current demands than a 0.5 A output card.
• Channel-level isolation: Each of the eight outputs forms its own isolated group.
• Clear channel count: The 8-output configuration distinguishes 7LB11 from the 16-output 7LA12.
• Defined lamp capacity: Siemens rates lamp loads up to 10 W per output.

Industries Served

Industry	Typical Application
• Manufacturing	Drives suitable 24 V DC machine auxiliaries and discrete production-line control circuits.
• Water Treatment	Provides on/off outputs for suitable valves, indicators and pump-control auxiliaries.
• Power Generation	Handles discrete DC signals for auxiliary equipment in S5-based plant controls.
• Chemical Processing	Controls suitable 24 V DC field devices across separate output channels.

Frequently Asked Questions

1. How many outputs does 6ES5454-7LB11 provide?
It provides eight digital outputs.
2. What is the rated current of each output?
Siemens specifies 2 A per output at a rated load voltage of 24 V DC.
3. Are the outputs isolated individually?
Yes. The manual lists optocoupler isolation in groups of one.
4. Is this a relay-contact output module?
No. It is a 24 V DC digital output module; the Siemens block diagram shows optocoupler and electronic output circuitry rather than relay contacts.
