Operating Instructions

3. Do not use a contact protection circuit as shown below:

Power

C

Load

This protection circuit is very effective in arc suppression

when opening the contacts. But, the capacitor is charged

while the contacts are opened. When the contacts are

closed, the capacitor is discharged through the contacts,

increasing the possibility of contact welding.

C

Load

Power

This protection circuit is very effective in arc suppression

when opening the contacts. But, when the contacts are

closed, a current flows to charge the capacitor, causing

contact welding.

Generally, switching a DC inductive load is more difficult than switching

a DC resistive load. Using an appropriate arc suppressor will improve the

switching characteristics of a DC inductive load.

3. Usage, transport, and storage conditions

1. Temperature, humidity, atmospheric pressure during usage,

transport, and storage.

 

Temperature: –40°C to +85°C (no freezing)

Humidity: 5 to 85%RH (no condensation)

The humidity range varies with temperature. Use within the

range indicated in the chart below.

2. Condensation

Condensation occurs when there is a sudden change in

temperature under high temperature and high humidity

conditions. The relay insulation may deteriorate due to

condensation.

3. Freezing

Condensation or other moisture may freeze on the relay when the

temperatures is lower than 0ºC. This causes problems such as

sticking of movable parts or delay in operation.

4. Low temperature, low humidity environments

Plastic parts may become brittle when used in low temperature

and low humidity environments.

4. Panel Mounting

When mounting DIN rail mount sockets on a panel, take the following

into consideration.

• Use M3.5 screws, spring washers, and hex nuts.

• For mounting hole layout, see dimensions on

• Keep the tightening torque within 0.49 to 0.68 N·m. Excessive

tightening may cause damage to the socket.

5. Others

1. General notice



To maintain the initial characteristics, do not drop or shock the

relay.



The relay cover cannot be removed from the base during

normal operation. To maintain the initial characteristics, do not

remove the relay cover.



Use the relay in environments free from condensation, dust,



The RF1V relay cannot be washed as it is not a sealed type.

Also make sure that flux does not leak to the PC board and

enter the relay.

2. Connecting outputs to electronic circuits:

When the output is connected to a load which responds very

quickly, such as an electronic circuit, contact bouncing causes

incorrect operation of the load. Take the following measures into

consideration.



Connect an integration circuit.



Suppress the pulse voltage due to bouncing within the noise

margin of the load.

3. Do not use relays in the vicinity of strong magnetic field, as this

may affect relay operation.

4. UL and CSA ratings may differ from product rated values

determined by IDEC.

6. Notes on PC Board Mounting

• When mounting 2 or more relays on a PC board, keep a minimum

spacing of 10 mm in each direction. If used without spacing of 10

mm, rated current and operating temperature differs. Consult IDEC.

• Manual soldering: Solder the terminals at 400°C within 3 sec.

• Auto-soldering: Preliminary heating at 120°C within 120 sec. Solder

at 260°C±5°C within 6 sec.

• Because the terminal part is filled with epoxy resin, do not excessively

solder or bend the terminal. Otherwise, air tightness will degrade.

• Avoid the soldering iron from touching the relay cover or the epoxy

filled terminal part.

• Use a non-corrosive resin flux.
