Compact Instrumentation System PD-N01

Hitachi compact instrumentation system, “PD-N01” is a newly conceived instrumentation system that enables advanced and complex analog control of temperature, flow rate and pressure by implementing an operation module of the distributed control system (DCS) for the programmable controller (PLC).
New concept instrumentation that utilizes the inheritance of the advantage of DCS such as powerful analog control function, rich monitoring and control software group and software assets and is compactified for the easy availability of hardware.

Feature

1.Full-scale Instrumentation System Composed of a General-purpose Computer and a PLC

The system adopts a general-purpose PC and a PLC, so it can be introduced at a lower initial cost. Further, maintenance costs can be reduced since the customer handles the maintenance and replacement of spare parts.

2.Supports Complicated Analog Control with a DCS Operating Module

Complicated loop control and sequence control is made possible with a PLC equipped with a DCS operating module. The system can achieve a high-level of continuous control and batch control, which conventional PLC instrumentation was said to be poor at.

3.Full Monitoring Operation Software and Engineering Tools are Available

A complete set of monitoring operation software necessary for handling graphics, trend and logs is available as standard. The engineering tools come equipped with the instrumentation oriented language SLC, which has a good track record in the Hitachi EX series, allowing the customer to construct a system easily.
