This standard specifies general technical requirements for hybrid and solid-state time relays with a maximum load current of 10A and a switching power below 300W DC or 1200VA AC. These relays are used in delay conversion circuits such as electronics, communication equipment, and automatic and motion devices. This standard is the basis for the design, production and use of electronic time repeaters, and is also the basis for formulating product standards.
