Product Description

Product Description

475 Field Communicator

A handheld operator, also known as a handheld controller, is a portable device designed to control various electromechanical equipment and systems. It serves as a convenient and user - friendly interface for operators to interact with machinery, enabling precise control over different operations.

Product name	Esito 475 Field Communicator
Brand	Esito
Output signal	2-20ma
Company website	Korei (Weifang) Automation Equipment Co., Ltd.

  

Powerful Processor and Sufficient Memory
The handheld operator communicates with the connected equipment or control system through specific communication protocols. It receives control commands input by the operator, such as start, stop, acceleration, and deceleration instructions. These commands are then transmitted to the target device, which could be a machine tool, crane, conveyor, or valve. In the case of controlling valves, for example, the handheld operator may receive a control signal from a regulator or a DCS (Distributed Control System). It calculates based on this signal and the feedback signal from the valve position, and then outputs an appropriate control quantity to drive the valve to the desired position.

 

Field Service and Commissioning
The hard handheld operator is a non - automatic control device. It only receives the valve signal. Through human - machine interaction, it controls the output. The output signal can be either forward and reverse electrical signals (D - type hard handheld operator) or linear current/voltage signals (Q - type hard handheld operator). By receiving the valve position signal, it can display the valve position, allowing the operator to determine the opening degree of the valve. This type is often used in situations where a simple and reliable manual control is required, such as in some small - scale industrial plants.

 

 

It can be equipped with different output types. For example, it may have one - way analog control output, which can be used to precisely adjust the operation of certain devices in a continuous manner. A one - way switch - quantity control output is suitable for applications that require on - off control, such as starting or stopping a pump. Some models also have relay forward and reverse control, which is useful for controlling motors that need to rotate in both directions. Additionally, an analog output is available, making it adaptable to various measurement and control occasions.
