The Pulse Encoder Interface module offers a differential or single ended interface for a digital pulse encoder. The module is capable of operating from either a 15 or 24VDC signal with a max frequency of 200kHz. This option uses 55 mA of the available 250 mA power supply. When the drive’s internal power supply is used to power the encoder, additional options may not be installed. Check the encoder’s power supply requirements prior to installation.
