Can the single phase signal of a rotary encoder be branched into three signals?

You can modify the input resistance of the PA-330Z into 1.5kΩ (charged optional).

 

Standard specification for input resistance of the PA-330Z is 470Ω. Also, one signal of RP series rotary encoder is matching to one input terminal of the PA-330Z (load resistance for RP series is 470Ω or more). In this reason, it is impossible to connect one signal of RP series into three input terminal of the PA-330Z with parallel circuit wiring. You can branch into three signals by modifying the input resistance for the PA-330Z from 470Ω into 1.5kΩ (optional). The following is schematic chart.

 

 

The above way to branch signal is applicable to each series of the RP-732, the RP-721 and the RP-704Z roller encoder.
