Product description
Digital tachometers with different voltage levels can be connected to the "digital tachometer interface" (DTI). The
inputs are electrically isolated (floating).
♦ HTL tachometers (high-voltage transistor logic, 11 V to 30 V)
♦ TTL tachometers (transistor- transistor logic, 5 V)
An additional 24 V DC power supply is required for the board.
♦ 0.3 A power supply module (option)
The current drain is a function of the encoder type.
