Introduction:

ELC2 is the newer version PLC in Eaton ELC series. There are some hardware differences between ELC
and ELC2 PLCs. This application note shows these differences in I/O terminals, wiring, memory maps
and other technical specifications. Other changes and differences between the ELC and ELC2 are
summarized below:

 The ELC2 models are 32-bit CPUs vs the ELCs that are 16-bit CPUs so they are faster and more

powerful

 The ELC-PC12NNAR has been obsoleted and there is no ELC2 replacement for this CPU
 The ELC-PA10AADR and ELC-PA10AADT will remain as being available as 16-bit controllers be-

cause of their 37mm width

 The ELC2-PA20 is a new addition which is 70mm wide and consisting of the ELC2-PA20AADR,

ELC2-PA20AADP and ELC2-PA20AADT

 All of the ELC2-PC controllers include high-speed 100kHz inputs as standard
 The ELC-PH will be replaced by an ELC2-PC model as there is no need to have separate high-

speed input models

 The ELC2-PE is a new CPU model (37mm wide) with on-board Ethernet communications consisting

of the ELC2-PE12NNDR and ELC2-PE12NNDT

 New PNP transistor output models for the ELC2-PB and ELC2-PV are available consisting of the

ELC2-PB12NNDP (12 vs 14 I/O - 8I/6O) and ELC2-PV28NNDP
