Per input
3.7.5 Input Circuit
(1) 12-24V is externally supplied to EXT-P. 5V cannot be used.
(2) When using sensors that require multiple power supply voltages, the voltage can be divided in
units of 8 bits.
(3) Fuses are provided by units of 8 bits.

3.7.6 Fuses and LEDs
This module is provided with a fuse for every unit of 8 bits to prevent burnout by overcurrent.
When a fuse blows, the corresponding P0 to P3 LED (Green) located above and below the connector goes
OFF.
(When a fuse blows, turn OFF the power and check the circuit. Then, turn ON the power after a while)
