Spare part for harsh environments
The 6AG1140-4DL04-4AB3 is a spare part SIPLUS IPC 427D based on 6AG4140-4DL04-3AB0, with conformal coating rated for 0…+55 °C. It ships with a Core i3-3217UE processor, 2x Gbit Ethernet (IE/PN), PROFIBUS DP 12, and an RS-232 port. The unit includes 4 GB NVRAM, a 32-bit Windows Embedded Standard 7 on 8 GB CFast, and WinAC RTX 2010 SP2 for soft PLC runtime.
Lifecycle and service posture
The spec field reads 'current', and the description explicitly labels it as a spare part. This combination indicates it is the designated replacement unit for the standard 6AG4140-4DL04-3AB0, intended for service in existing installations rather than new system builds.
Mounting and environment readiness
Mounts to the wall — no PCIe expansion. The conformal coating protects against condensation and mild chemical splash, making it a candidate for food processing environments where standard electronics corrode. PROFIBUS DP 12 and dual Ethernet ports keep it compatible with existing Siemens automation networks. The Windows Embedded 7 environment runs WinAC RTX, so a soft PLC can coexist with HMI or data logging.
