ATTENTION
The
ioPAC RTU controller only supports up to 2 85M-5401-T modules.
Block Diagram
Below is the 85M-5401-T modules block diagram. This module communicates with the modular head by USB
and UART. The MCU processor accesses I/O information through the GPIO pin. The 85M-5401-T has isolation
protection up to 3K VDC or 2K Vrms, and magnetic isolators between the I/O and the MCU processor.
