MeloAuto-Trusted PLC & DCS Parts Supplier
Board Overview
This standard I/O module combines analog input and output capabilities in one unit. You can install FUJI NP1AYH4V-MR directly into FUJI SPH series PLC racks. The unit accepts four analog sensor signals and generates two analog control outputs. It eliminates the need for separate input and output modules in small systems.

Board Layout and Components
The PCB separates analog input circuits from output drive sections. Four multiplexed input channels share a single 14-bit ADC. Additionally, 156 discrete components include precision voltage references and output buffers. Tantalum capacitors provide stable power for accurate conversions. Consequently, measurement errors stay below 0.2% of full scale.
Installation Process
You can mount FUJI NP1AYH4V-MR into any standard SPH series rack slot. The backplane connector supplies power and communicates with the CPU. Furthermore, a front panel screw terminal block accepts field wiring for all six channels. Clear labeling identifies each input and output terminal for easy connection.
Performance Advantages
This module completes all six channel conversions within 2 milliseconds. Each input channel independently selects voltage or current mode through software. Therefore, you can mix sensor types without external signal conditioners. The 12-bit outputs also provide smooth control for actuators and valves.
Safety and Compliance
FUJI NP1AYH4V-MR meets CE and RoHS industrial standards. The board stores minimal electrical energy after system power-down. Hence, technicians face no capacitor discharge hazards during routine maintenance.
