GUIDELINES FOR SIGNAL RELAYS USAGE

Long term current carrying

A circuit that will be carrying a current continuously for long periods

without relay switching operation. (circuits for emergency lamps, alarm

devices and error inspection that, for example, revert only during

malfunction and output warnings with form B contacts) Continuous,

long-term current to the coil will facilitate deterioration of coil insulation

and characteristics due to heating of the coil itself.

For circuits such as these, please use a magnetic-hold type latching

relay. If you need to use a single stable relay, use a sealed type relay

that is not easily a󰀨ected by ambient conditions and make a failsafe

circuit design that considers the possibility of contact failure or

disconnection.

DC coil operating power

Steady state DC current should be applied to the coil. The wave form

should be rectangular. If it includes ripple, the ripple factor should be

less than 5%.

However, please check with the actual circuit since the electrical

characteristics may vary. The rated coil voltage should be applied to

the coil and the set/reset pulse time of latching type relay di󰀨ers for

each relays, please refer to the relay's individual specications.

Coil connection

When connecting coils of polarized relays, please check coil polarity

(+,-) at the internal connection diagram (Schematic). If any wrong

connection is made, it may cause unexpected malfunction, like

abnormal heat, re and so on, and circuit do not work. Avoid

impressing voltages to the set coil and reset coil at the same time.

Maximum allowable voltage and temperature rise

Proper usage requires that the rated coil voltage be impressed on the

coil. Note, however, that if a voltage greater than or equal to the

maximum continuous voltage is impressed on the coil, the coil may

burn or its layers short due to the temperature rise. Furthermore, do

not exceed the usable ambient temperature range listed in the catalog.

Maximum allowable voltage for coil

In addition to being a requirement for relay operation stability, the

maximum continuous impressed coil voltage is an important constraint

for the prevention of such problems as thermal deterioration or

deformity of the insulation material, or the occurrence of re hazards.

Temperature rise due to pulse voltage

When a pulse voltage with ON time of less than 2 minutes is used, the

coil temperature rise bares no relationship to the ON time. This varies

with the ratio of ON time to OFF time, and compared with continuous

current passage, it is rather small. The various relays are essentially

the same in this respect.

Operate voltage change due to coil temperature rise

(Hot start)

In DC relays, after continuous passage of current in the coil, if the

current is turned OFF, then immediately turned ON again, due to the

temperature rise in the coil, the pick-up voltage will become somewhat

higher. Also, it will be the same as using it in a higher temperature

atmosphere. The resistance/temperature relationship for copper wire

is about 0.4% for 1°C, and with this ratio the coil resistance increases.

That is, in order to operate of the relay, it is necessary that the voltage

be higher than the pick-up voltage and the pick-up voltage rises in

accordance with the increase in the resistance value. However, for

some polarized relays, this rate of change is considerably smaller.

Dew condensation

Condensation occurs when the ambient temperature drops

suddenly from a high temperature and humidity, or the relay

and microwave device is suddenly transferred from a low

ambient temperature to a high temperature and humidity.

Condensation causes the failures like insulation deterioration,

wire disconnection and rust etc.

Panasonic Corporation does not guarantee the failures caused

by condensation.

The heat conduction by the equipment may accelerate the

cooling of device itself, and the condensation may occur.

Please conduct product evaluations in the worst condition of

the actual usage. (Special attention should be paid when high

temperature heating parts are close to the device. Also please

consider the condensation may occur inside of the device.)

Icing

Condensation or other moisture may freeze on relays when the

temperature become lower than 0°C.This icing causes the sticking of

movable portion, the operation delay and the contact conduction failure

etc. Panasonic Corporation does not guarantee the failures caused by

the icing.

The heat conduction by the equipment may accelerate the cooling of

relay itself and the icing may occur. Please conduct product

evaluations in the worst condition of the actual usage.

Low temperature and low humidity

The plastic becomes brittle if the switch is exposed to a low

temperature, low humidity environment for long periods of time.

High temperature and high humidity

Storage for extended periods of time (including transportation periods)

at high temperature or high humidity levels or in atmospheres with

organic gases or sulde gases may cause a sulde lm or oxide lm to

form on the surfaces of the contacts and/or it may interfere with the

functions. Check out the atmosphere in which the units are to be

stored and transported.

Package

In terms of the packing format used, make every e󰀨ort to keep the

e󰀨ects of moisture, organic gases and sulde gases to the absolute

minimum.

Cleaning

1) Although the environmentally sealed type relay (plastic sealed type,

etc.) can be cleaned, avoid immersing the relay into cold liquid (such

as cleaning solvent) immediately after soldering. Doing so may

deteriorate the sealing performance.

2) Surface mount terminal type relay is sealed type and it can be

cleaned by immersion. Use pure water or alcohol-based cleaning

solvent.

3) Cleaning with the boiling method is recommended (The temperature

of cleaning liquid should be 40°C or lower).

Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may

cause breaks in the coil or slight sticking of the contacts due to the

ultrasonic energy.

Please refer to "the latest product specications"

when designing your product.

•Requests to customers:

https://industrial.panasonic.com/ac/e/salespolicies/

Storage requirements

Since the SMD type is sensitive to humidity it is packaged with tightly

sealed anti-humidity packaging. However, when storing, please be

careful of the following.

1) Please use promptly once the anti-humidity pack is opened.(Signal

relay: within 3 days, Max. 30°C/70%RH). If left with the pack open,

the relay will absorb moisture which will cause thermal stress when

reow mounting and thus cause the case to expand. As a result, the

seal may break.

2) When storing for a long period after opening the anti-humidity pack,

you must take measures to prevent humidity, for example, by storing

in the open location of a promptly re-sealed anti-humidity pack after

it is used or in a humidity controlled desiccator. You may also store

it in an anti-humidity bag to which silica gel has been added.

* If the relay is to be soldered after it has been exposed to excessive

humidity atmosphere, cracks and leaks can occur. Be sure to mount

the relay under the required mounting conditions

3) The following cautionary label is a󰀩xed to the anti-humidity pack.

Silicon

When a source of silicone substances (silicone rubber, silicone oil,

silicone coating materials and silicone lling materials etc.) is used

around the relay, the silicone gas (low molecular siloxane etc.) may be

produced.

This silicone gas may penetrate into the inside of the relay. When the

relay is kept and used in this condition, silicone compound may adhere

to the relay contacts which may cause the contact failure. Do not use

any sources of silicone gas around the relay (Including plastic seal

types).

NOx Generation

When relay is used in an atmosphere high in humidity to switch a load

which easily produces an arc, the NOx created by the arc and the

water absorbed from outside the relay combine to produce nitric acid.

This corrodes the internal metal parts and adversely a󰀨ects operation.

Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use

at high humidity is unavoidable, please contact our sales

representative.
