Siemens 6ES5095-8MB03 SIMATIC S5 Compact Unit

This compact unit combines a CPU and I/O interfaces in a single housing. It serves small-scale automation tasks without requiring additional rack components. Therefore, this solution saves valuable space inside control cabinets.

Physical Dimensions and Mounting Specifications

The Siemens 6ES5095-8MB03 features a slim base housing for direct panel mounting. Its total width measures 100 mm for tight installation spaces. The unit depth reaches 120 mm including all connectors. Consequently, technicians can place this device near existing machinery.

Interface Types and Connector Layout

The Siemens 6ES5095-8MB03 provides one RS-232 serial port for programming. A second RS-422/485 interface supports networked communication with other controllers. The front panel carries a 20-pin I/O connector for field devices. Hence, users can wire sensors and actuators directly to this unit.

Component Count and Onboard Features

This compact unit contains one main circuit board with surface-mounted components. The board holds a 8-bit microprocessor running at 10 MHz. You will also find 8 digital inputs and 6 digital outputs onboard. These components eliminate the need for separate I/O modules.

Energy Storage and Power Requirements

The Siemens 6ES5095-8MB03 requires a 24V DC external power supply. It draws 200 mA under normal operating conditions. An internal supercapacitor retains user data for 72 hours after power loss. This energy storage eliminates the need for a separate backup battery.

Operating Conditions and Durability

The unit withstands ambient temperatures from 0°C to 55°C. Its housing carries an IP20 protection rating for dry indoor use. Therefore, this compact unit performs reliably in control rooms and clean factory floors.
