The PA-330Z receives the square wave signals from the rotary encoder, and converts it to low impedance signals suitable for long distance transmission after wave-shaping and amplifying via photo couplers which provide isolation between input and output.

A 12VDC external power supply is provided for use with the DC powered RP series encoder.

The case is sealed construction which allows closely mounting to the encoder.

  Modifying item Modified specification Standard specification
1 Open Collector output Maximum rating Collector output
2 Change of power-supply voltage AC 110 V AC 100 V
AC 200 V
AC 220 V
3 Change of input resistance 1.5 kΩ 470 Ω
47 kΩ *
4 Change of output resistance 220 330 Ω (3-phase)

* When using C specification of the RP-1700 Series (collector output/pull-up resistor 470 Ω) ,
it is necessary to modify the input resistance to 47 kΩ.
