Siemens 6ES5182-3KH61 SIMATIC S5 ER 182 Expansion Rack

The 6ES5182-3KH61 provides additional I/O slots for the S5-115U system. This expansion rack connects to a central controller using a standard interface module. It allows engineers to add up to eight extra modules per unit. Consequently, you can scale your automation system without replacing existing hardware.

You will need an IM312 or IM313 interface card for proper operation. The 6ES5182-3KH61 accepts all standard S5-115U I/O modules. These include digital, analog, and communication processors. Therefore, this rack offers complete flexibility for system expansion.

Physical Construction and Slot Configuration

This expansion rack features eight module slots in a single row. The 6ES5182-3KH61 measures 250 mm in height, matching all S5 hardware. A built-in power supply provides the necessary 5V and 24V DC. Below is a complete breakdown of its technical characteristics.

Interface Connection and Module Compatibility

A single 20-pin connector sits on the right side of the rack. The 6ES5182-3KH61 uses a flat ribbon cable for interface communication. This cable can extend up to 10 meters from the central rack. Eight green LEDs indicate active power delivery to each slot position.

This expansion unit does not contain any logic or processing capability. The 6ES5182-3KH61 simply provides mechanical support and electrical distribution. You can mix any S5-115U modules across the eight available slots. Therefore, configuration remains highly adaptable for various applications.

Operational Benefits for System Scalability

This expansion rack allows you to distribute I/O across a factory floor. The 6ES5182-3KH61 requires no additional programming for basic operation. You just need to configure the interface module correctly. Maintenance teams appreciate the modular design for quick troubleshooting.
