Yaskawa JACP-317120 PLC Power Supply Module (PS-01)

Yaskawa JACP-317120 PLC Power Supply Module (PS-01)

The Yaskawa JACP-317120 (often identified by its model code PS-01) is a high-reliability power supply module designed for the CP-317 and CP-9200SH series control systems. 

It provides the necessary regulated DC power to the CPU, communication interfaces, and backplane I/O modules.

This module is a core component of the Control Pack Series, which Yaskawa developed as a functionally-distributed hierarchical control system for large-scale industrial plants.

Technical Parameter Table

Product Advantages and Features

Wide Input Range: Capable of handling both AC and DC 100V inputs, providing flexibility in different industrial power environments.1

High Reliability: Specifically designed for the "Control Pack" architecture, which is famous for its "100% market share" in critical applications like domestic blast furnace plants in Japan.

Redundant Capabilities: In certain chassis configurations, these modules can be paired to ensure that a power supply failure does not result in a system-wide shutdown.

Industrial Hardening: Features robust noise filtering and surge protection, essential for maintaining stable logic levels in high-EMI environments like steel mills.

Status Monitoring: Typically includes LED indicators for "Power OK" and "Fault" conditions for rapid visual diagnostics.

Application Cases

The JACP-317120 is almost exclusively used in high-availability industrial systems:

Blast Furnace Control: Powering the master control units in metallurgical plants where continuous operation is safety-critical.

Water Treatment Facilities: Providing power to the main CPU racks managing large-scale pump and filtration sequences.

Complex Assembly Lines: Used in the master controllers of automotive body shops that synchronize hundreds of I/O points across multiple racks.

Retrofit Projects: Often sold as a replacement part for legacy CP-317 systems that have been in operation for decades but require new power components for continued service life.
