Panasonic relay classification
Classification of Panasonic relays and their selection conditions
  Relay protection can be divided into: unilateral steady state type, single coil self-holding type, and double coil self-holding type.

Unilateral steady state type (common relay):

When the unilateral steady state relay coil is energized, the relay is set, and when the coil is powered off, it is reset.

Single-coil self-retaining type:

The single-coil self-locking relay has a self-sustaining structure, the relay will keep its position unchanged after a forward pulse is input on the coil, and the reverse pulse relay will be reset.

Dual-coil self-retaining type:

The self-protection structure of the double-coil self-retaining relay is composed of two coils, the set coil and the reset coil, the relay is set after the set coil is added to the pulse, and the relay is reset after the reset coil is added to the pulse.

Select the conditions for the Panasonic relay

The first thing to do is to understand the necessary conditions. the mains voltage of the control circuit that can provide current; voltage and current in the controlled circuit; How many sets of contacts are required for the controlled circuit. When selecting a relay, it can be selected according to the power supply voltage of the general control circuit. The controller should be able to provide sufficient operating current to the relay, otherwise the relay engagement is unstable. After referring to the relevant information to determine the conditions of use, you can search for the relevant information to find the model and specification number of the required relay. If you already have a relay, you can check if it can be used based on the data. See if the size is appropriate. Check the capacity of the instrument. If it is a general electrical appliance, in addition to considering the volume of the box, the installation layout of the circuit board is mainly considered for small Panasonic relays. For small electrical equipment such as toys and remote control, ultra-small relay products should be selected.

The above are the classification and selection conditions of Panasonic relays.
