Key Features
-
All-in-One Compact Design – Integrates CPU, 24V DC power supply, and I/O into a single compact housing (135 × 145 × 150 mm), reducing cabinet space and eliminating the need for a separate rack and backplane
-
Dual AS511 Programming/Communication Interfaces – Two serial interfaces for simultaneous connection to a programmer (PG) and an operator panel/terminal (OP), enhancing system versatility
-
Comprehensive Onboard I/O – 16 digital inputs (24V DC sinking), 16 digital outputs (24V DC sourcing, 0.5A each), 8 analog voltage inputs (0–10V), and 1 analog output (0–10V / 0–20mA, switchable)
-
Interrupt and Counter Functions – 4 interrupt inputs and 2 counter inputs (Counter A: 5 kHz, Counter B: 2 kHz) integrated into the digital inputs
-
Expandable Architecture – Supports expansion with up to 32 peripheral modules from the S5-100U series
Technical Parameters
Core Advantages
1. Dual AS511 Interfaces for Flexible Connectivity
The -8MC02 provides two independent AS511 serial interfaces on the front panel. This allows simultaneous connection to a programming device (PG) for online monitoring and program modifications, and to an operator panel (OP) or terminal for HMI functionality — without needing to disconnect one to use the other. This dual-port capability makes the 6ES5095-8MC02 particularly valuable in applications requiring both programming access and operator interface on the same controller.
2. All-in-One Architecture for Compact Control
The S5-95U integrates the CPU, 24V DC power supply, and all onboard I/O into a single compact housing. This eliminates the need for a separate rack, power supply module, and I/O cards, significantly reducing cabinet space and simplifying installation. The turnkey design makes it ideal for OEM machinery, standalone control panels, and building services applications where panel space is at a premium.
3. Comprehensive Onboard I/O
The 6ES5095-8MC02 provides a versatile I/O mix directly on the CPU: 16 digital inputs (including 4 interrupt and 2 counter inputs), 16 digital outputs (0.5A sourcing, short-circuit protected), 8 analog inputs, and 1 analog output that can be switched between voltage (0–10V) and current (0–20mA) modes. This onboard capability handles many applications without requiring additional expansion modules.
4. Expandable for Larger Applications
Despite its compact size, the S5-95U can be expanded with up to 32 peripheral modules from the S5-100U series, including digital I/O, analog I/O, and special function modules. This scalability makes it suitable for a wide range of application sizes, from simple standalone control to more complex systems.
5. Proven Legacy Platform with Migration Path
The SIMATIC S5 series has a long track record of reliable operation in demanding industrial environments. For new installations or major redesigns, the closest modern equivalent is the S7-1200 (CPU 1214C for compact applications) or S7-1500 (CPU 1511 for higher performance). However, STEP 5 programs do not auto-convert to STEP 7 — migration requires manual porting guided by Siemens migration documentation.

Frequently Asked Questions (FAQ)
Q1: What is the Siemens 6ES5095-8MC02?
It is a compact central processing unit from the SIMATIC S5-95U series. It integrates the CPU, 24V DC power supply, and I/O into a single housing, featuring two AS511 serial interfaces for connecting a programming device and an operator terminal simultaneously.
Q2: What distinguishes the -8MC02 from other S5-95U variants?
The -8MC02 is a later revision of the -8MC01, offering the same two AS511 serial interfaces — one for a PG (programming device) and one for an OP (operator panel). Other variants offer a single programming port plus PROFIBUS (MB), PROFIBUS-DP slave (MD), or PROFIBUS-DP master (ME) functionality.
Q3: What I/O does this module provide?
It provides 16 digital inputs (24V DC sinking, including 4 interrupt and 2 counter inputs), 16 digital outputs (24V DC sourcing, 0.5A each, short-circuit protected), 8 analog inputs (0–10V DC), and 1 analog output (0–10V / 0–20mA, switchable).
Q4: How much program memory does the 6ES5095-8MC02 have?
It has 16 KB of memory total, with the full capacity available for user program instructions.
Q5: Can I expand the S5-95U with additional I/O?
Yes. The S5-95U can be expanded with up to 32 peripheral modules from the S5-100U series, including digital I/O, analog I/O, and special function modules. These modules mount on the same standard rail and connect via a special connector on the right side of the CPU.
Q6: Is this a genuine Siemens product?
Yes. This is a genuine Siemens module manufactured in Germany. Depending on availability, units may be new original or professionally refurbished.
Q7: Is the SIMATIC S5 series still in production?
No. The SIMATIC S5 series has been discontinued by Siemens and replaced by the S7 series. The S5-95U is available only through third-party suppliers and remaining stock.
Q8: What is the modern replacement for the S5-95U?
The closest functional equivalent is the S7-1200 (CPU 1214C for compact applications) or S7-1500 (CPU 1511 for higher performance). Both are programmed in TIA Portal with STEP 7. STEP 5 programs do not auto-convert — migration requires manual porting.
Q9: What is the weight of this module?
Approximately 1.38 kg.
Q10: What should I verify before ordering?
Always verify the exact part number (6ES5095-8MC02), confirm your system requirements (dual AS511 ports for PG and OP), and check whether your application requires onboard analog I/O, counters, or expansion modules.
