Ratings and Specifications
Fiber Amplifier Units
*1.
The E3X-DA0-S Amplifier Unit allows you to use an E3X-ECT EtherCAT Sensor Communications Unit or E3X-CRT CompoNet Sensor Communications Unit.
*2.
Only for Pre-wired models.
*3.
The following details apply to inputs.
*4.
The communications function and mutual interference prevention function are disabled if the detection mode is set to Super-high-speed mode.
*5.
Mutual interference prevention is enabled if Fiber Amplifier Units are connected together. It is also enabled in the same way if E3X-DA-S-series
Units and E3C-LDA-series Units are used together. If power tuning is enabled, mutual interference prevention can be used for up to six units.
*6.
For the standard models E3X-DA
@
-S (
@
: 21/51/7/9/0), the rated sensing distance is approximately 1/2 and the incident level is approximately
1/3 of the normal levels when ECO mode is enabled.
