Multi Loop Controller

1. BEFORE STARTING

1.1 Overview

■ML Series product family

Multi-channel temperature control system (ML-D, ML-D2H), event output (ML-E)

■ Module composition method (Individual product is called “Unit”)

ML Series products can be made up as one module by connecting maximum of 31 units without wiring

work, and only one Unit is connected to power cable and communications line (RS485). Event output

(ML-E) is not included in maximum connection quantity, and only one Unit is connected during module

composition and used.

■ Product run through communications connection

For RS232C and RS485 communications method, this product supports PC-Link, PC-Link with SUM,

Modbus, ASCII/RTU protocols. Through individual communication with product, it is operated with

reading/writing of Register address defined based on function. Basic functions such as control and

monitoring can be tested or operated using operating program provided in the computer.

RS485 communications : For use, connect to communications terminal at low part, and this standard is

used when operating multiple units since communications are achieved only

through address set as switch in front side.

RS232C communications : For use, connect to Loader Jack at front part, and only connected unit is

communicated regardless of front side switch setup. It is for unit’s initial setting.

■ Input type

Thermocouple (12 types) : K, J, E, T, R, B, S, L, N, U, W, PL2

RTD (2 types) : Pt100, KPt100

DC voltage (3 types) : 0 – 10 V, 1 -5 V, 0 – 100 mV

Direct current (4 – 20 mA) : Set input type as direct current (1 -5 V), attach 250 Ω of electric resistance

at both ends of input terminal

Current Transformer (CT) : 2 channel, AC 1 – 50A (primary current measuring range), apply only to ML-D2H

■ Control output type

Depending on output type of model composition, fixed in one among REALY, voltage pulse (SSR), and

current output (SCR).

■ Control method

2 DOF (Degree of Freedom) PID control (auto tuning support), ON/OFF control

ML-D2H: 2 Channel, Universal control (Selectable Heating or cooling control) or Heating/Cooling

simultaneous controlling

ML-D4: 4 Channel, Universal control (Selectable Heating or cooling control)

■ Installation

Can attach onto panel by fixing in DIN 35 mm standard rail or using screw

1.2 Product verification

For product purchase, please first verify desired specifications, and then damages in exterior and parts
insufficiency. And contact sales department of this company if found different specifications, exterior damage, or
parts insufficiency.
