5 Inputs and Outputs
The following chapter introduces the Input and Output Channels.

5.1 Input Channels

The M 60 provides diverse analog inputs which allows the direct connection of a multipli-
city number of sensors.
The M 60 analog inputs accept an input signal of 0 to 5 V. A 3.01 kOhm pull-up resistor
can be activated by software.
The digital inputs of the M 60 accept 0 V to 5 V signals of Hall-effect sensors by default.
Connect the output of the Hall-effect sensor to the REVn_P pin and leave the REVn_M pin
open. Support of inductive speed sensors is available as a hardware option. Inductive
sensors are connected to the REVn_P and REVn_M pins.

5.2 Output Channels

This chapter describes the PMW Output and Sensor Power Supply of the M 60.
The M 60 has 4 low side switch outputs controlled by pulse width modulation (PWM).
Each switch is rated 1 A maximum current. Maximum PWM switch frequency is 1 kHz with
a 0 % ... 100 % duty cycle. Each output is short circuit protected to GND and battery
voltage. It is mandatory to connect the LS_PWM pins to vehicle GND as indicated in the
circuit diagram when using the PWM outputs.
The M 60 has three types of sensor power supply:
– 12 V unregulated battery voltage
– 5 V regulated voltage
– 10 V regulated voltage
The 12 V unregulated output is fused and rated 1 A max. The regulated 5 V and 10 V out-
puts can deliver 350 mA each. They are short circuit protected to battery voltage and
GND.
