Maximal permitted electrical Load
• Max. current (track handling): 1.0 A.
• Max. current (supplied by EPOS2 Module 36/2):
Note
*1) Voltage level “low” = 0 V, “high” = 3.3 V, connected directly to the DSP
*2) EIA RS232 Standard
*3)Total ampacity on voltage 5 VDC is 150 mA and divides as follows:
• Encoder supply v5 VDC/100 mA
• Hall sensor supply v5 VDC/30 mA
• Auxiliary output v5 VDC/20 mA
