The voltage supplied to the "IN" connector of the Q5B reaches 4.75 VDC or higher on the condition that the voltage drop (V)
at the extension cable between the main base unit and Q5B is 0.15 VDC or lower.
When connecting GOT by extension cable that is 13.2m or longer, the bus extension connector box A9GT-QCNB is
required.
Since the A9GT-QCNB is supplied with 5VDC from the power supply module loaded on the main base unit, 30mA must be
added to "Im" as the current consumption of the A9GT-QCNB.
For details of the method for GOT bus connection, refer to the following.
