Specifications

General information

Max. power consumption – Encoder power supply 5 V	P Module [mW] = 25 V * ((I Encoder [mA] * 0.42) + 0.45) (note: I Encoder ... Current consumption of the incremental encoder. The current consumption of the terminating resistors is already taken into account in the formula. A voltage drop on the encoder cable of max. 2x 1.5 V is also taken into account.)
Max. power consumption – Encoder power supply 24 V	P Module [mW] = 25 V * (I Encoder [mA] + 0.45) (note: I Encoder ... Current consumption of the incremental encoder. The current consumption of the terminating resistors is already taken into account in the formula.)
