Omron, E3X-DRT21-S VER.3

• ON/OFF signals and incident light levels can be sent to the host PLC without any need for programming (DeviceNet communications slave functionality).

• Threshold values and function settings can be read, written, or taught (using the Message Communications function).

• Simply connect the communication cables and slide the Amplifiers from the side for wire-saving.

• Up to 16 Sensor Amplifiers can be connected.

*1. When any of the following Sensors is connected, two words are allocated per Sensor and each Sensor is counted as
two Sensors for the number of connected Sensors.
E3X-DA[]-S ([]: 7/9), E3X-DA[]TW-S ([]: 6/8), E3X-MDA[] ([]: 6/8), E3C-LDA[] ([]: 6/8), E2C-EDA[] ([]: 6/8)
*2. Communications is possible for the ON/OFF output data from 13 Units. One word is allocated as the input area in the
Master.
*3. Communications is possible for the ON/OFF output data from 16 Units and the number of connected Sensors. Two
word sare allocated as the output area in the Master.
*4. Communications is possible for the ON/OFF output data from 16 Units, the number of connected Sensors, and the
detection levels for the connected Sensors.
Two words are allocated as the input area and one word is allocated for the number of connected Sensors in the
Master.
*5. Connection cannot be performed if the response speed of the Sensor is set to super-high-speed mode.
*6. This does not include the current supplied to the Sensor.

Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
