Eaton EASY-E4-UC-16RE1P Smart Relay Expansion Module, 8 Digital Inputs, 8 Relay Outputs, DIN Rail 197511

When a control system needs more I/O than the base unit provides, this expansion module adds eight digital inputs and eight relay outputs to an Eaton EASY-E4 smart relay. It eliminates the need for a larger, more expensive controller by extending the existing system with screw-terminal connections and DIN rail mounting.

Who is it for

Panel builders, machine OEMs, and maintenance technicians who already use Eaton EASY-E4 base units and need additional I/O for small automation tasks such as conveyors, pumps, lighting, or access control. It suits applications where space is limited and wiring must remain simple and serviceable.

Main features

• 8 digital inputs, usable as 24 V DC digital or 0–10 V analog inputs
• 8 relay outputs with normally open contacts, rated up to 8 A (AC-15/DC-13) or 10 A (AC-1)
• Powered directly from the EASY-E4 base unit—no separate supply needed
• DIN rail mounting for quick installation in control cabinets
• Screw terminals for secure, maintenance-friendly wiring
• IP20 protection, suitable for clean, enclosed environments

Tips

Check the I/O count of your existing EASY-E4 base unit before ordering. This module is not a standalone controller—it requires a compatible base unit. For high-current loads, use external contactors or relays to protect the module outputs.
