Relay Output Features and Protection Systems

The FUJI NB2W36R uses sixteen Form A relays for discrete output control. Specifically, each relay switches up to 2 amps at 250 VAC or 30 VDC. In addition, internal flyback diodes protect the relay coils from inductive back EMF. Moreover, each channel includes an independent green LED for visual status monitoring. Furthermore, a replaceable fuse provides overcurrent protection for all output circuits. Thus, this module protects both the PLC and connected field devices effectively.

High-Density Output Configuration

Sixteen relay output channels fit into a single rack slot with this module. For instance, you can control up to sixteen solenoid valves or contactors with one module. In addition, the relay type allows switching of AC or DC loads without polarity concerns. Moreover, the removable terminal block accepts 18-22 AWG stranded or solid wires. Therefore, this module saves valuable rack space in large control systems.

Energy Storage and Operational Stability

This PLC module stores energy using four onboard capacitors for power filtering. Specifically, two electrolytic capacitors smooth the 5 VDC supply for stable relay coil operation. In addition, two tantalum capacitors provide high-frequency noise suppression for logic circuits. Furthermore, these capacitors maintain relay status during brief power interruptions. Consequently, the FUJI NB2W36R continues operating through minor supply dips reliably.

Installation and Diagnostic Indicators

Eighteen LED indicators provide operational status at a glance on this module. First, sixteen green LEDs light when each corresponding output channel turns on. Second, a green Power LED indicates the presence of backplane operating voltage. Third, a red Fault LED illuminates during overcurrent or fuse failure events. Additionally, the module includes a locking lever for secure rack attachment. Thus, you can diagnose system status instantly without external tools.
