Chapter 4: eMotionBlox-40M XIO Output Signals The eight digital outputs share a common, high-side (sourcing) driver IC. The driver is designed to supply any kind of load with one side connected to ground. It is designed for a range of user-provided voltages from 10 to 24 VDC, and each channel is capable of up to 0.7 A of current. This driver has overtemperature protection, current limiting, and shorted-load pro- tection. In the event of an output short or other overcurrent situation, the affected output of the driver IC turns off and back on automatically to reduce the temperature of the IC.
The driver draws power from the primary 24 VDC input to the eMB-40M through a self-resetting poly- fuse. The outputs are accessed through direct connection to the XIO connector (see XIO Signal Desig- nations on page 34), or through the optional XIO Termination Block. See the documentation supplied with the Termination Block for details. 19148-000 Rev.
