The standard setting of the encoder power supply is 5V; when operating with HTL interface board without

subsequent electronics 12V.

Current consumption of PWM 8 when powered via DC-IN socket:

(measured with 11µApp interface board)

Voltage at DC-IN 10 V 12 V 15 V 20 V 24 V 30 V

PWM 8 current consumption 500 mA 420 mA 350 mA 270 mA 230 mA 200 mA

PWM 8 current consumption

with encoder (100 mA)

580 mA 480 mA 400 mA 310 mA 260 mA 220 mA

6.1.2 Power Supply of PWM 8 and Encoder via the Encoder Output

(OUT) of the Interface Board

PWM 8 can be integrated into the encoder circuit. For this purpose the subsequent elec-tronics must be

connected to the encoder output (OUT) of the interface board. The supply voltage for PWM 8 is taken from

the subsequent electronics. In order to reduce the power consumption of the subsequent electronics, the

background lighting of the display is auto-matically switched off!
