Smart relays, or Logic relays, are essentially a simplified PLC with limited functionality. They are designed to replace a number of standard electromechanical and electronic relays as found in machine automation where the task does not require a full PLC.

Typically, a smart relay is programmed in a simplified ladder logic or function block format.
Ladder logic is generally a better understood programming format in New Zealand, so we have chosen the ladder logic programming format. The smart relays include input coils and output contacts, internal coils and contacts, timers, counters, time clocks and messages.

Smart relays can be used to provide control functions requiring multiple timers, counters and relays and replace a moderate circuit with multiple components with a single component at a fraction of the price.
