When is the Omron NX-PD1000 power supply unit required?
The built-in NX unit power supply of an NX controller (NX1P2, NX102) or EtherCAT coupler provides up to 10 W. When the cumulative NX bus power consumption of connected NX units reaches this 10 W budget, an NX-PD1000 additional power supply unit must be inserted to refresh the bus voltage and initiate a new power segment.
What is the difference between NX-PF0630 and NX-PF0730?
Both units supply 24 VDC I/O power to connected output and input terminals. The NX-PF0630 supports up to 4 A maximum I/O current, whereas the NX-PF0730 supports up to 10 A. They are required when field sensor/actuator currents exceed base unit ratings or when isolating voltage zones.
How many NX modules can be connected to an Omron NX1P2 PLC?
The NX1P2 compact controller supports up to 8 NX I/O units directly on its internal bus. For larger configurations, expand via EtherCAT with an NX-ECC Coupler (supporting up to 63 units) or upgrade to the NX102 series (supporting 32 units).
How many NX modules can be connected to an Omron NX102 PLC?
The NX102 series controller supports up to 32 NX units mounted directly to the CPU base. Additional units can be connected as remote I/O via EtherCAT couplers (up to 63 units per node).
Is the NX-END01 end cover unit mandatory?
Yes, an NX-END01 or NX1-END02 end cover (12 mm width) is mandatory at the rightmost end of every Omron NX rack to protect bus contacts and secure the assembly.
