Product Description

The NFPW444-50 is a specialized DC-to-DC power converter module within the Yokogawa control system family. Designed as a high-efficiency power interface, this module accepts a standard 24V DC field supply and converts it into a precision-regulated +5.1V DC rail. This low-voltage output is critical for powering internal logic circuits, backplane communications, and microprocessor components within industrial controller racks.

Engineered for reliability in non-hazardous environments, the NFPW444-50 features a compact form factor that allows for high-density installation. Its wide input tolerance ensures that system logic remains stable even during common industrial DC bus fluctuations. As a “Basic Type” module (-50 suffix), it provides essential power distribution without explosion protection, making it a cost-effective choice for standard control room applications.

Technical FAQ

Can the NFPW444-50 be used in hazardous (Ex) areas?
No. The NFPW444-50 is a standard-type (code 5) module without explosion protection. For hazardous environments, an intrinsically safe or explosion-proof variant must be used.

Does this module support 110V AC input?
No. The NFPW444-50 is strictly a DC-input module and requires a stable 24V DC source. If AC power is the primary source, an upstream AC-to-DC rectifier is required.
