PURPOSE OF MANUAL

This manual (Issue 2.0) describes the Basic Version and all options for 7100S series

solid state contactors with current ratings of up to 250 A.

General information about the digital communication option is presented in the

technical specifications (section 1).

The operation of 7100S units with this option and the operation of the digital

communication are described in the ‘7000 Series. Digital Communication’ manual

(part number HA176664ENG available later).

Applicable standards

EUROPEAN DIRECTIVES AND APPLICABLE STANDARDS

COMPLIANCE WITH PRODUCT STANDARD

7100S products comply with the terms of product standard EN 60947-4-3

‘Contactors and motor-starters - AC semiconductor controllers and contactors for non-

motor loads’. The number of this standard is indicated on the front panel label.

CE LABELLING

7100S products, installed and used in accordance with their user manual, bear CE labelling

to indicate compliance with the essential requirements of:

• the European Low Voltage Directive 73/23 EEC dated 19 February 1973

Applicable standards

EMC FILTER conducted emissions)

For facilities required to comply with the levels stipulated under the generic standard for

conducted emissions, EN 61000-6-4, Eurotherm Automation can provide optional internal

filters (code FILT) on units up to 100 A.

EMC GUIDE

To help you deal with installation-dependent electromagnetic interference effects,

Eurotherm provides an ‘Electromagnetic compatibility’ installation guide

(ref. HA025464) which sets out best current practice regarding EMC.

Chapter 1 IDENTIFICATION

GENERAL PRESENTATION

7100S series solid state contactors are used to control the electrical power of single phase

industrial loads. The load controlled may comprise low temperature coefficient resistive

loads or short wave infrared (SWIR) elements.

Current ratings vary from 16 A to 630 A (see coding), at voltages of 100 V to 690 V.

7100S series power thyristor units (rating of up to 100 A) comprise two channels, one

controlled by thyristors and one direct internal channel.

7100S units rated 125 A and above only comprise a single controlled channel.
