PD47] as necessary. This pin is available only with MRJ5-_A_-RJ.
This is available as an input device of a sink interface. If using it, assign the input
device with [Pr. PD43] to [Pr. PD46] as necessary. In addition, supply + of 24 V DC
to the CN3-12 pin.
This is available as an input device of a source interface. If using it, assign the input
device with [Pr. PD43] to [Pr. PD46] as necessary.
