How can I convert an existing industrial relay into a time relay?

There are two ways to retrofit an existing industrial relay with timing functions.
Time cubes are ideal when a socket and relay are already installed and only a single timing function needs to be added. The time cube is simply plugged between the socket and the relay and adjusted via DIP switch or potentiometer. It is available for industrial relay series C2 and C3, as well as for the Long Life series C2x and C3x.

Alternatively, time modules can be used. These modules are inserted into the socket’s module compartment and, compared to time cubes, offer more timing functions and longer setting ranges. They are available for sockets S3-M0, S3-M0R, S3-M1, S3-M1R, S5-M, and S5-MR and are compatible with industrial relays C3 and C5, as well as Long Life relays C3x.

Both solutions allow time relays to be configured with up to three changeover contacts – more than is usually possible with standard time relays.
