Galvanic coupling Galvanic coupling generally develops between two circuits
using a common cable. Typical interference sources are
starting motors, static discharge, clocked devices and
potential difference between the component enclosure and
their common power supply.
GND Abbreviation for “GROUND” (0 potential).
hexadecimal Numerical system with the base 16. The count starts at 0 to
9 a continues with the letters A, B, C, D, E and F.
I/O Abbreviation for “Input/Output“.
Impedance Alternating current-resistance of a component or of a circuit
consisting of several components at a specific frequency.
Low-impedance connection Connection with low alternating-current resistance.
Inactive metallic parts Touch-protected conductive components, isolated electri-
cally from active metallic parts by means of an insulation,
but subject to fault-voltage.
Inductive coupling Inductive (magnetic) coupling develops between two
current-carrying conductors. The magnetic effect generated
by the currents induces an interference voltage. Typical
interference sources are, for example transformers, motors,
mains cables installed parallel and RF signal cables.
Capacitive coupling Capacitive (electrical) coupling develops between two
conductors carrying different potentials. Typical interfer-
ence sources are, for example parallel signal cables,
contactor relays and static discharge.
Coding element Two-part element for the unambiguous allocation of elec-
tronic and basic module.
Command modules Command-capable modules are modules with an internal
memory that are capable of executing particular commands
(such as output substitute values).
Configure Systematic arrangement of the I/O modules of a station.
short-circuit proof Property of electrical equipment. Short-circuit-proof equip-
ment has the ability to withstand the thermal and dynamic
loads that may occur at the location of installation on
account of a short-circuit.
