Protection The FIO expander has two fast acting, 5mm x 20mm glass fuses:
• A 2A fuse for the FIO expander’s power
• A 4A fuse for the I/O bus edge connector
The power and network ports comply with the EMC requirements
EN50491-5-2.
Status indicators LEDs indicate status of communications, system state (running or errors),
outputs, and power
Environmental operating
