Eaton - Cutler Hammer ELC2-PE12NNDR PLC, 24VDC, 5mA, 8Digital In, 4 Relay Out, Ethernet, RS232/485, ELC2 Series

ELC2 is the newer version PLC in Eaton's ELC Series. There are some hardware differences between ELC and ELC2 PLCs:
• 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 Because of Their 37 mm Width
• The ELC2-PA20 Is a New Addition Which Is 70 mm Wide and Consisting of the ELC2-PA20AADR, ELC2-PA20AADP and ELC2-PA20AADT
• All of the ELC2-PC Controllers Include High-Speed 100 kHz 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 (37 mm 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 — 8 I/6 O) and ELC2-PV28NNDPThere are many new instructions for ELC2 series:
• Basic Instructions Can Be Used to Manipulate the Bits in a Word Device, e.g. BLD D0 K7 (LD D0.7)
• Basic Instructions Can Be Used with Index Devices, e.g. LD X0E1
• Floating-Point Comparison Input Instruction: FLD>, FLD?, FLD
