Sensor Port 24VDC (Pin 1) and GND (Pin 3)
Pin 1 of each Sensor Port provides 24V for powering up a sensor device and/or for supplying the load for
the Aux I/O (Pin 2) when configured as an output. The available current for the two control ports on the
module is limited internally by a solid-state fuse. The maximum combined current consumption for the two
sensor ports is 100 mA.
Motor Port
Supported motor types Senergy Ai
PWM frequency* 25 kHz +/- 0.1%
Maximum starting current 8A
Maximum rated current 3A
Motor Protection**
Coil-to-coil short, coil-to-Vcc short, overheating, over-voltage, under-voltage,
stall sensing and protection
• The PWM frequency is firmware version dependent
Current in excess of 100mA drawn from the sensor port’s 24V pin may cause permanent
damage to the sensor detection circuit. Care should be taken to avoid excess loads, short
circuits and miss-wiring of the sensor port.

**During normal operation as an MDR port, the internal protection circuitry is not capable of
detecting a short-circuit between a BLDC coil output and ground. Such a short-circuit will
