E3NC
Amplifier Units
*1. Two sensor outputs are allocated in the programmable logic controller PLC I/O table.
PLC operation via Communications Unit enables reading detected values and changing settings.
*2. Applicable Sensor Head is the series of E3NC-LH@@ (Input/Output 10-30V DC Class 2)
*3. At Power Supply Voltage of 10 to 30 VDC.
Normal mode: 1,650 mW max. (Current consumption: 55 mA max. at 30 VDC, 115 mA max. at 10 VDC)
Eco ON: 1,410 mW max. (Current consumption: 47 mA max. at 30 VDC, 95 mA max. at 10 VDC)
Eco LO: 1,530 mW max. (Current consumption: 51 mA max. at 30 VDC, 105 mA max. at 10 VDC)
*4. The total for both outputs of a model with 2 outputs is 100 mA max. (Residual voltage: Load current of less than 10 mA: 1 V max., Load current of 10 to 100 mA: 2 V max.).
*5. The following details apply to the input.
*5-1.Input time is 25 ms (ON)/(OFF) only when (in tUnE) or (in PtUn) input is selected.
*6. The mutual interference prevention function is disabled if the detection mode is set to super-high-speed mode.
*7. When connected to an OMRON NJ-series Controller.
*8. The bank is not reset by the user reset function or saved by the user save function.
*9. Eco LO is supported for Amplifier Units manufactured in July 2014 or later.
