Eaton easyE4 DC 4PE1 RTD Input Expansion Module, 4 Channels, Pt100/Pt1000/Ni100/Ni1000, Screw Terminals, DIN Rail, 24 V DC

Temperature monitoring in industrial automation often requires more RTD inputs than a basic PLC can provide. The Eaton EASY-E4-DC-4PE1 expansion module adds four RTD input channels to your easyE4 control system, enabling precise temperature measurement for process control, HVAC, and machine monitoring.

Who is it for

Automation engineers and panel builders who need to expand the analog input capability of an Eaton easyE4 PLC with reliable RTD temperature sensing. Ideal for applications requiring multiple temperature points without replacing the entire controller.

Main features
