Detailed Specifications

Understanding Timer Functions

The FCT18-X multifunction timer relay offers 10 different timing modes, each designed for specific control applications:

ON-Delay Functions (Ak, As, Je, A)

In ON-delay mode, the timer begins counting when the trigger signal is received, and the output relay activates after the preset time period. This is useful for delayed equipment startup sequences or staged process initiations.

OFF-Delay Functions (Q, Gr, B)

With OFF-delay modes, the output relay activates immediately when the trigger signal is received and deactivates after the preset time period once the trigger signal ends. This function is ideal for applications requiring equipment to continue running temporarily after the control signal stops.

Repeat Cycle Functions (Ck, Dk)

Repeat cycle modes provide automatic cycling between ON and OFF states according to preset time intervals. Ck starts with the OFF state while Dk starts with the ON state. These functions are perfect for applications needing repeated operations like irrigation systems or periodic sampling.

ON-OFF Delay Switching (L)

This specialized function combines ON and OFF delay features, allowing for complex timing sequences in a single function. It’s particularly useful in applications requiring precise control of both activation and deactivation timing.
