Product Overview
The Siemens 6ES5 452-8MR11 is a four-channel relay output module in the SIMATIC S5 range. It turns controller commands into relay-contact signals for discrete field circuits. Its contacts are rated for DC and AC loads, while each output is galvanically isolated. The module is listed for S5-90U, S5-95U and S5-100U controllers, plus ET 100U and ET 200U distributed I/O.

Features
• Four relay-contact outputs
• Galvanic isolation for each output
• AC and DC load-switching capability
• 24 V DC supply for the relays
• Contact protection using switching varistors
Model Benefits
• Four independent control points: Handles separate on/off signals within one module.
• Relay flexibility: Suitable for discrete circuits with differing AC or DC load requirements.
• Individual isolation: Each relay output is isolated, supporting separation between field circuits.
• Defined load ratings: Siemens specifies different switching limits for resistive and inductive loads.
Industries Served
Industry
Typical Application
• Manufacturing
Provides discrete relay signals for machine auxiliaries, indicators and production-line control circuits.
• Water Treatment
Supports on/off control signals for pump-related and plant auxiliary circuits.
• Power Generation
Handles discrete switching signals in S5-based auxiliary control systems.
• Chemical Processing
Connects controller commands to suitable AC or DC field-control circuits.
Frequently Asked Questions
1. How many relay outputs does 6ES5 452-8MR11 have?
It has four relay outputs—not eight. Siemens identifies this exact model as a four-output module.
2. Can it switch both AC and DC loads?
Yes. Siemens specifies contact switching capacities for both 250 V AC and 30 V DC loads. The allowable current depends on whether the load is resistive or inductive.
3. What powers the module’s relays?
The rated relay supply is 24 V DC, with a permissible range of 20–30 V DC.
4. Which S5 systems is this module associated with?
Siemens lists it for S5-90U, S5-95U, S5-100U, ET 100U and ET 200U systems.
