Precautions
When mounting a number of relays on a PCB, be sure to provide a minimum mounting space of 5 mm between the two juxtaposed relays as shown below.
The above minimum mounting space is necessary due to mutual thermal interference generated by the relays. This restriction may be ignored, however, depending on the operating conditions of the relays. Consult OMRON for details.
There is no restriction on the mounting direction of each relay on the PCB.
When using this circuit, confirm the set and reset states and then take into account the circuit constant.
