UniStream 5″ built-in
Compact all-in-one PLC + HMI with built-in I/O.
- 5″ colour touch, 800×480
- Built-in I/O depending on variant + expansion
- Ethernet, USB, RS485
Scalable control with integrated or modular HMI, advanced communication and motion in one development environment.


Compact all-in-one PLC + HMI with built-in I/O.

The most popular size for machine builders – display, PLC and I/O in one unit.

Large operator interface with built-in I/O for complex machines.

The largest built-in: 15,6″ PLC + HMI without built-in I/O – expand with Uni-I/O via a rear adapter or Remote I/O.

HMI panel + snap-in CPU. Build exactly the I/O configuration the machine requires.

Compact HMI panels from 5″ to 21,5″, IP66/NEMA4X when panel-mounted.

DIN-rail CPU for control without a local HMI – operate via web or a remote panel.

Compact DIN-rail PLC with built-in I/O and Virtual HMI – operated from web, PC or a Light panel.
Modular and PLC without display: Uni-I/O and Uni-COM snap directly onto the CPU. Built-in (5″, 7″, 10,1″): have I/O in the housing; extra Uni-I/O requires a local expansion kit (UAG-CX) for DIN rail, and Uni-COM must be the CX type.

Snap-in I/O for UniStream – directly on the CPU or in a local expansion on DIN rail.
Fits: Modular & PLC: snaps directly onto the CPU · Built-in: via local expansion kit

Extra RS232, RS485 and CANbus ports plus EtherCAT master for UniStream.
Fits: Choose module series by controller: CX for built-in, CB and EtherCAT master for PLC without display (USC-B5/B10), standard for modular CPU (CPU-for-Panel)

Move Uni-I/O out onto DIN rail and add more modules than there is room for on the controller.
Fits: UAG-CX for built-in · UAG-XK for modular & PLC

Spare fronts for UniStream built-in and modular HMI panels – with or without Unitronics logo.
Fits: UniStream built-in 5″/7″ and modular HMI panels
