Table 36: PT1001-A1 'PACE-Bus' (RS485) connector - 'X2'

The PT1001-A1 provides 4 logic control outputs on the connector 'X3'.
The logic control outputs are used to activate LEDs or communicate a status
change of the system.
The logic control outputs are open collector outputs which switch to IO-GND. A
power source is required to use the outputs.
●
Max. current per output is 200 mA.
●
Max. current on internal 12 V power source is 250 mA.
