The RTN-2 relay has one normally closed contact.
The relay uses a PLC-9 type pad, i.e. like a finger 9-pin lamp.
Contacts 3 and 4 are closed to each other. It’s the same with contacts 8 and 9.
These pairs open when the bimetallic plate is heated.
The plate is heated by applying voltage to contacts 1 and 6.
The heater voltage is 6.6 volts.
The response time is 4 seconds.
The switched voltage is 220V DC or 115v AC.
The switching current is 0.2 A DC or 1A AC with a frequency of 50 Hz.
