RELAYS Panasonic

| Kategorie: Katalog  | Tento dokument chci!

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.

The coil impressed voltage the switching tests rectangular wave at the rated voltage. Coil ON voltage OFF — ON Form A contact OFF Form B ON contact OFF J T Operate time Relay release time for Form A contact only 5. Operate Time The elapsed time from the initial application power the coil, until the closure the Form (normally open) contacts. 3.DEFINITION RELAY TERMINOLOGY ELECTRICAL PERFORMANCE 1. Insulation Resistance The resistance value between all mutually isolated conducting sections of the relay, i. - Between coil and contacts - Between open contacts - Between contact sets 2. 5. Except where otherwise specified, the tests above are conducted under standard temperature and humidity (15°C 35°C 59°F 95°F, to 85%). Electrical Life The minimum number times the relay can operated under nominal conditions with specific load being switched the contacts. 2) Destructive The vibration which can withstood by the relay during shipping, installation or use without suffering damage, and without causing change its operating characteristics. (With multiple pole devices the time until the last contact closes. Release Time The elapsed time from the initial removal of coil power until the reclosure the Form (normally closed) contacts (last contact with multi-pole). However, test was performed total of times, six times each three-axis directions. Usually the stated value VAC (RMS) for one minute duration. Expressed an acceleration G's displacement, and frequency range. 6. Release time MECHANICAL PERFORMANCE AND LIFE 1. Contact Bounce (Time) Generally expressed time (ms), this refers the intermittent switching phenomenon the contacts which occurs due the collision between the movable metal parts contacts, when the relay operated released. Shock Resistance 1) Functional The acceleration which can tolerated by the relay during service without causing the closed contacts open for more than the specified time. Mechanical Life The minimum number times the relay can operated under nominal conditions (coil voltage, temperature, humidity, etc. This value usually expressed as “initial insulation resistance” and may decrease with time, due material degradation and the accumulation of contaminants. 4. Usually expressed in “G”s. 2.e. 2. Notes: 1. 168 ds_x61_en_relay_technical_information_010113J . However, test was performed total six hours, two hours each three-axis directions.) This time does not include any bounce time. Breakdown Voltage (Hi-Pot or Dielectric Strength) The maximum voltage which can be tolerated the relay without damage for a specified period time, usually measured the same points as insulation resistance. 4. Maximum Switching Frequency This refers the maximum switching frequency which satisfies the mechanical life electrical life under repeated operations applying pulse train at the rated voltage the operating coil. Vibration Resistance 1) Functional The vibration which can tolerated by the relay during service, without causing the closed contacts open for more than the specified time. This time does not include any bounce time.
