Connecting Sensors
Connecting Sensors
Connectable Sensors
The Communication Unit can be connected with the following Sensors.
An optional reduced-wiring connector (i.e., slave connector or cordless connector) is
required to connect the Sensor.
• If the Sensor is connected using a connector with a cable, external noise may prevent correct
communication of ON/OFF signals to the Communication Unit.
• Note that prewired models cannot be connected. Connecting these units will disable the power reset
function.
• E3X-DA-N series cannot be connected.
• Lot No. of E3X-DRT21-S must use it since November 1, 2008 when you use the function only of shape
E3X-DA7 and E3X-DA9.
