Panasonic is part of a large worldwide groupselling relays and associated switching products under different brand names in different territories.The conditions of use in some territories may differ from those customary in Europe. In particular there are often major differences in regard to national and international specifications, such as UL, CSA, VDE, SEV, EVE, SEMKO, etc. Thus, when considering contact loads as stated in this catalogue (e.g. 10 A, 30 VDC for the SP relay) its hould be understood that these values are not necessarily an absolute maximum but tested ratings. Mostly the stated value has been tested for a certain life expectancy as stated by the manufacturer or the respective test house. Thus, under different conditions, the stated “maximum” may, in practice, be safely exceeded.
2) models
When connecting coil surge protection
circuit these relays, recommend a
Zener diode least resistor
(2,800Q 4,700Q). Please check the circuit and make
sure the diode not connected parallel
with the coil drive circuit.
3.
Please sure not use the product
until you have evaluated under actual
load conditions. Part numbers with diodes
Since these relays use diode the coil
surge protective element, the reset time
is slower and reduction expected life
is possible compared part numbers
without protective elements and part
numbers with resistors. Please check the circuit and make
sure the diode not connected parallel
with the coil drive circuit.
.
When the diode connected parallel
to the coil, the reset time will slow down,
which may lead shortening expected
life. Part numbers without protective
elements
1) models
When connecting coil surge protection
circuit these relays, recommend a
Zener diode least resistor
(680Q 1,000Q). Part numbers with resistors
Since these part numbers use resistor
in the coil surge protection circuit, an
external surge protection element not
required.
When the diode connected parallel
to the coil, the reset time will slow down,
which may lead shortening expected
life.
2.CAUTIONS FOR PROTECTIVE ELEMENTS
1. Please note that connecting a
diode parallel with the coil will
decrease the reset time and possibly
reduce the expected life the product.
