APU 8-13 : the Perfect I/O extender
APU 8-13 is the most suitable I/O extender for control of common electrical functions. It comes as a slave in an architecture mastered by a Safety Power Unit (SPU). APU 8-13 comes with a library to integrate into the master application software, that manages the protocol for communicating over a dedicated CAN with the slaves. As the I/Os are directly controlled in the SPU application, there is no need for additional development.
