1 Introduction
This manual is intended to provide guidance for the installation, operation and maintenance of the HiD 2000 range
of intrinsic safety isolators.
To avoid damage, failure or improper operation, carefully read this manual before installing and operating the unit.
This manual and the related equipment should not be used by untrained personnel unless they are fully acquainted
with the principles of intrinsically safe system.
Elcon Instruments has published a complete tutorial entitled “Guide to Intrinsic Safety” covering most aspect of
intrinsic safety. The book can be obtained from Elcon Instruments free of charge.
1.1 Overview
The Elcon HiD 2000 Series is designed to be used in connection with process instrumentation system and consist
of a range of compact I.S. isolating interface modules to handle the input and output signals of a process plant.
Moreover a range of standard and custom made Termination Boards are available where the modules can be
plugged and quickly secured.
With this new full line of modular plug-in I.S. isolator a significant cost reduction is achieved in project planning,
plant design commissioning and service.
The module pack one, two or four isolated channels into a compact housing which can be inserted or removed
from the Termination Board without disturbing any of the wiring, no specialist knowledge is required, thereby
eliminating a frequent source of errors. The new “Quick Lok” method of fixing the module without the need for
tools reduces installation time and is very ease to operate. Pushing down a tab on each side of the module rotates
a securing foot which locks the unit to the Termination Board; to remove the modules simply lift the tabs. For
servicing, only the defective module needs to be removed and the replacement module plugged into the
Termination Board and locked by the quick mechanism. No special knowledge is required, the signal cables don’t
need to be detached and re-connected, eliminating a frequent source of errors.
Polarisation on the Board securely prevents modules from being swapped inadvertently.
The HiD 2000 Series product range has:
• high packing density, due to innovative circuit design using advanced surface mount components
• high performance, with high signal transfer accuracy and repeatability, low consumption, low heat
dissipation
• wide functionality, with a wide range of I/O signals, galvanic isolation, line fault alarm
• HiD 2000 Series products are Intrinsic Safety Certified according to CENELEC, CSA, FM, GOST, SEV,
SABS, SAA and other world-wide standards. Moreover, they meet European directives on EMC, and all
modules carry the CE marking.
