Omron Fiber Amplifier Sensor Communication Unit 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
