EM4-101-DD1 is Eaton Moeller easy400 EM4 series compact PLC controller. It integrates digital input and output points, powered by DC24V, supports basic logic, timer, counter and simple function block programming. It can connect expansion modules and touch panels via communication port, widely used for small automation equipment, conveyor systems and packaging machinery control. It is an end-of-life spare part for legacy Moeller easy400 automation systems.

This DIN rail mounted module adopts IP20 protection class, installed inside control cabinet. Built-in program memory and data memory, program developed with Moeller easySoft software. Front panel LED indicators show input, output, power and running/fault status for quick on-site diagnosis. Equipped with digital I/O terminals and communication interface for HMI or other controllers. Supports pulse output for simple positioning tasks.

Built-in EMC protection circuit resists interference from inverters and servo drives. Operating temperature range 0~55℃, suitable for general factory cabinet environment. It supports password protection for user program, backup and restore function for project files.

EM4-101-DD1 is obsolete Moeller PLC spare part. Many legacy small automation machines adopt this CPU for logic control. When the original module fails, replacement with identical EM4-101-DD1 can reuse DIN rail installation, I/O wiring and existing PLC project. Technicians install the module, download program and test input/output logic, so machine control system resumes operation and reduces production downtime.

Before shipment, every EM4-101-DD1 undergoes comprehensive functional inspection including power-on self-test, I/O point test, communication port verification and program read-write inspection. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, program download and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, EM4-101-DD1 is reliable spare compact PLC CPU for legacy Moeller easy400 control systems. It restores machine logic control function, guarantees equipment normal operation, extends service life of automation assets and avoids whole control cabinet renovation.
