The 140EHC20200: It draws 4.0 W from the backplane, carries CE and UL 508 marks, and is rated for FM Class 1 Division 2 hazardous locations.
The 140EHC20200 has 2 channels; the 140DAI55300 discrete input module has 4 channels and 32 inputs, but lacks high-speed counting and FET outputs — choose the 140EHC20200 when encoder feedback or fast pulse capture is needed.
