CHAPTER 1 INTRODUCTION

Fonctioning:

The temperature control relays are equiped with a sensor input that permits to use multiple types of

sensors (PT100 probe, thermocouple, current or voltage sensors depending the model), one or two

process outputs (relay, solid state relay interface or analog) for heating, cooling or heating and

cooling regulation based on PID algorithm.

The measured temperature and the setpoint can be displayed in °Celsius or °Fahrenheit.

Advanced functions are embedded: Ramps (up to 16), hysteresis, fuzzy logic, auto tuning, soft

start, alarms.

The temperature controllers can be setup using the front face interface or through a common

software by a communication port and the integrated Modbus.

This communication port provides intergartion capability in an itelligente architecture supervised by

Magelis terminal or controled by PLCs(Twido, M340 or Premium) to exchange setpoints, process

values and alarms.

Application examples:

The temperature controllers Zélio control REG provide a solution for temperature control in the

following applications:

- Ovens and furnaces,

- Extrusion lines,

- Plastic and rubber presses,

- thermo-forming,

- Production of synthetic fibres an polymerisation,

- Food and drink processing lines,

- Moulding presses,

- Environmental chambers, overhead furnaces and test benches,

- UV &laser technologies,

- Cabin of painting,

- Cold rooms,

- Horticultural and livestock farms,

- Maintening the temperature of a colour bath…
