Eaton easyE4 DC 8TE1 Digital I/O Expansion Module, 4DI/4DO, 24V DC, Transistor PNP

The Eaton easyE4 DC 8TE1 expansion module stands apart by delivering a compact, all-in-one digital I/O solution tailored for easyE4 control relays. Unlike generic add-ons, it integrates four 24 V DC inputs and four transistor (PNP) outputs in a single DIN-rail unit, simplifying wiring and reducing cabinet clutter. Its plug-in design enables seamless expansion of your automation system without complex configuration, making it a practical choice for machine builders and panel designers who need reliable, high-density I/O in a small footprint.

Highlights

• 8 digital channels: 4 inputs and 4 outputs, all 24 V DC
• Transistor outputs with PNP switching, 0.5 A per channel
• DIN rail mounting for quick installation
• IP20 protection, suitable for control cabinets
• Wide operating temperature range: -25 °C to +55 °C
• Global certifications: CE, UL, cUL, EAC, RCM, KCC, DNV GL

In daily use

In practice, the module connects directly to an easyE4 base unit via the expansion interface, instantly adding I/O capacity for tasks like sensor monitoring, actuator control, or signal conditioning. The screw terminals accept wires up to 1.5 mm², ensuring secure connections even in vibration-prone environments. Because the outputs are transistor-based, they switch silently and withstand frequent operations—ideal for solenoid valves, indicator lamps, or small DC motors. The module's compact width of 35.5 mm conserves rail space, allowing multiple units to be mounted side by side.
