Multi Digital Controller

FX SeriesEasy Control & Best Price

FX series has easy settings and excellent transfer among each menu based on simple and convenient

constitution, and it embeds a step-by-step access setup function (blind menu function), so that it can

prevent the equipments from malfunction. Also, it can provide users with very reasonable price in

contradistinction with cost in spite of a combination of network ability and control function.

±0.3, Precise Temperature Control & High Reliability

The temperature sensors, such as NTC (-50~150), PT-100 (-200~800) and TC (0~1000)

can measure temperature in wide range and provide users with very fine tolerances

(0.1 temperature resolution).

Free Voltage & Compact Design

There is no restriction to apply for AC100~240V and 50/60Hz.

A simple and streamline shape provides users with visible convenience.

Error & Alarm Display

FX series can show the error information, such as failure and malfunction of the equipment

as a simple message, so the supervisors can easily manage it.

Multi Digital Controller (MICOM) Function

FX series is an advanced multi function digital controller which embeds logic at the same level of MICOM

according to models and various functions and oversteps bounds of simple temperature controllers.

RS485 & 4~20mA Analogue Output Function

Applying for RS485 communication method based on MODBUS RTU/ASCII Protocol,

FX series helps users to construct convenient SCADA/HMI system which is possible for precise central

concentrated monitoring with PLC, PC, and touch screen.

Compatibility for Various Sensors

According to request for each system, various types of sensors are applicable including a standard

temperature sensor.
