7.1.8 Logic outputs
The PT2001-A1 provides 4 logic outputs. They are open collector transistors
switching to GND.
The 4 logic outputs can be used to switch lamps, relays or other devices with a
current draw of max. 200 mA.
The output can be powered with the DC 10 V provided on pin 12 of the connector,
or with a voltage of max. DC 36 V.
