Terminal block ................................................................................................................ X59
Terminal number ................................................................................... 1
Driver type .............................................................................................................. Push/Pull
Logic ................................................................................................................ PNP or NPN
Voltage level ....................................................................................................... 0 - 24 V DC
Max. output current (sink or source) with internal power supply (total ) ..............................40 mA
Max. output current (sink or source) with external power supply (per output) ..................... 100 mA
1) Terminals X59-1 and X59-2 can be programmed as input, parameter 33-60.
2) Selected in parameter 5-00 Digital I/O mode.
Combined digital inputs/outputs
