Why Choose the Unitronics USC-P-B10 UniStream CPU-for-Panel?

The Unitronics USC-P-B10 is a powerful PLC CPU module designed for the UniStream® modular automation platform. It acts as the processing core of a UniStream system and is designed to attach directly to the back of a compatible UniStream HMI panel, forming a complete PLC + HMI industrial control solution.

Unlike conventional PLCs, the USC-P-B10 cannot operate independently. Instead, it plugs into a UniStream touchscreen panel which supplies power and provides the operator interface. Together with optional Uni-I/O™ and Uni-COM™ modules, the system forms a flexible modular controller suitable for complex industrial automation systems.

The UniStream architecture enables engineers to configure the controller with exactly the I/O and communication modules required. Local I/O modules can snap directly onto the controller, while remote expansion is possible via expansion kits and network connections, allowing systems to scale to thousands of I/O points in large automation installations.

UniStream Modular Automation Platform

The UniStream platform combines a touchscreen HMI, powerful PLC CPU and modular I/O expansion into a single scalable automation system. The USC-P-B10 CPU serves as the central processing unit, while UniStream HMI panels provide the operator interface and power supply.

Programming is performed using the Unitronics UniLogic development environment, which integrates PLC programming, HMI design and communication configuration in a single software platform.

Typical Applications

Industrial machine automation.
Process control systems.
Large OEM automation equipment.
Manufacturing production lines.
Industrial systems requiring scalable I/O expansion.

Frequently Asked Questions

What is the USC-P-B10 used for?

It is the main CPU module used in Unitronics UniStream modular PLC systems and must be installed on the back of a UniStream HMI panel.

Can the CPU operate without an HMI panel?

No. The CPU-for-Panel must connect to a UniStream HMI, which supplies power and provides the operator interface.

How many I/O points can the system support?

Depending on configuration and expansion modules, UniStream systems using the USC-P-B10 can support up to approximately 2048 I/O points.

Which software is used to program the controller?

The controller is programmed using Unitronics UniLogic software for PLC logic, HMI screens and communications configuration.
