The High Transistor Logic (HTL) is a type of Push Pull. So VW3A3405 or 06 or 07 Encoder option Board, depending on the excitation power required, can be used for HTL Signal Encoders.

The power consumption of the HTL Encoder should be in accordance to 175mAmps maximum up to 15V and 100mAmps up to 24V, or else external excitation will have to be added.
